HIV replication requires conversion of the genomic RNA present in the infecting virus to a double stranded DNA that integrates into a human chromosome. Unlike DNA polymerase, HIV reverse transcriptase catalyzes DNA chain elongation from either a DNA or RNA template. Azidothymidine (AZT) was the first effective drug used to inhibit HIV reverse transcriptase and went into clinical use in 1987 to treat AIDS. What best describes how AZT inhibits reverse transcriptase
Answers
Answer:
AZT inhibits reverse transcriptase enzyme.
Explanation:
AZT inhibits reverse transcriptase enzyme that is used by the virus to make a DNA copy of its RNA. This Azidothymidine prevent reverse transcriptase enzyme from doing its function properly. Due to absence of this enzyme, the HIV virus is unable to make copies of its DNA and this Azidothymidine stops the life cycle of the virus and slows the growth of AIDS disease so that's why this drug was considered effective against HIV virus and used in the treatment of AIDS disease.
4. Explain How can a pedigree help identify both phenotypes and genotypes? SC.7.L.16.2
Answers
A pedigree can help identify both phenotypes and genotypes by showing the inheritance patterns of traits within a family lineage.
A pedigree is a graphical representation of an individual's family tree that can be used to track the inheritance of traits or genetic conditions. It can help in identifying both phenotypes (observable traits) and genotypes (genetic compositions) by analyzing the patterns of inheritance within a family.
By studying a pedigree, one can observe the presence or absence of a particular trait across generations. This allows for the identification of phenotypes within the family members. For example, if a specific trait, such as a genetic disorder or a physical characteristic, is consistently seen in multiple individuals across generations, it suggests the presence of the phenotype.
In terms of genotypes, a pedigree can provide clues about the inheritance pattern of a trait. By analyzing the distribution of the trait in the family, one can make inferences about the underlying genotypes. Patterns such as autosomal dominant, autosomal recessive, X-linked dominant, or X-linked recessive inheritance can be identified, which can help determine the possible genotypes of individuals.
Additionally, when additional genetic information is available, such as genetic testing results, it can be integrated with the pedigree to further confirm or refine the identification of specific genotypes associated with the observed phenotypes.
Overall, a pedigree serves as a valuable tool in unraveling the relationship between phenotypes and genotypes within families, enabling the identification and understanding of inherited traits or genetic conditions.

The density of gas particles in a section of Earth's atmosphere decreases. Which of the following is the most likely explanation for this event?
The air pressure in that section of Earth's atmosphere decreased.
The air pressure in that section of Earth's atmosphere increased.
The total number of gas particles in Earth's atmosphere decreased.
O The total number of gas particles in Earth's atmosphere increased.
Answers
The most likely explanation for the decrease in the density of gas particles in a section of Earth's atmosphere is that the air pressure in that section of the atmosphere decreased.
Density is defined as mass per unit volume. In the case of a gas, density is directly related to the number of gas particles (molecules or atoms) present in a given volume. When the air pressure decreases, it means that there are fewer gas particles exerting force per unit area. As a result, the density of gas particles in that section of the atmosphere decreases.
Air pressure is the force exerted by the gas particles on the walls of the container or the surroundings. It is influenced by several factors, including temperature, altitude, and the presence of other gases. Changes in these factors can cause fluctuations in air pressure. For example, if there is a decrease in temperature, the gas particles lose kinetic energy, which leads to decreased pressure and density.
It is important to note that the total number of gas particles in Earth's atmosphere does not necessarily change significantly over short periods of time. The atmosphere is composed of a vast number of gas molecules, and while there may be variations due to natural processes, such as volcanic eruptions or biological activities, these changes are relatively small compared to the overall composition of the atmosphere.
Therefore, the most likely explanation for the decrease in density of gas particles in a section of Earth's atmosphere is a decrease in air pressure, which can occur due to various factors such as weather systems, changes in altitude, or movement of air masses.

For this discussion post, I read the article “A creator of ‘CRISPR babies’ nears release from prison, where does embryo editing stand?
This article explained how biophysicist He Jiankui, who used the genome editor CRISPR to create the world's first genetically engineered babies, may be released from prison this week.
His November 2018 announcement about gene editing was well received. Still, Fyodor Urnov sees no circumstance that would justify efforts to modify babies genetically. Urnov supports using CRISPR to fix disease-causing mutations after birth. The work has proceeded with little notice, and oversight measures to stop rogue experiments like He's have stalled. A study showed how CRISPR could get rid of a newly fertilized egg of an extra copy of a chromosome. This problem can lead to Down syndrome and other medical conditions. The initial concerns about designer babies centered on CRISPR's sloppiness. But a study of CRISPR-altered human embryos found 16% had these "unintended editing outcomes" at the targeted DNA, and genetic screening of edited IVF embryos might not catch these errors. Stem cell researcher Dietrich Egli hopes to find a way to start and stop CRISPR at the embryo's single-cell stage. In a preprint posted on bioRxiv on 10 March, Egli's group demonstrated a strategy for trisomy, an errant third chromosome, by targeting an extra paternal or maternal chromosome copy with a CRISPR cut at or near its centromere.
If CRISPR does not correct the trisomy in all of the cells in an early embryo, a natural "rescue mechanism" might eliminate the abnormal cells. However, there are still multiple obstacles to overcome. Researchers are trying to use CRISPR to edit human embryos but need help beyond science. Editing the DNA of egg or sperm precursor cells may avoid some of these hurdles, improving the odds of getting it right. Orwig's team is exploring a different route to creating edited sperm stem cells by reprogramming adult human cells into a stem cell state and trying to coax them partly down the pathway that produces sperm. However, reprogrammed adult cells only survive when placed into newborn animals, which is unrealistic for humans. Scientists say the increased awareness of CRISPR's shortcomings has underscored the recklessness of transplanting edited embryos with today's technology. Still, some scientists are openly advocating for the practice.
find something interesting and 1-2 questions about the summary
Answers
One interesting aspect of the article is the discussion around using CRISPR to edit disease-causing mutations after birth, rather than in embryos.
What is the authenticity if genetically modifying babies ?Fyodor Urnov supports this approach and believes that there is no circumstance that would justify modifying babies genetically. This raises the question of whether there is a moral or ethical line that should not be crossed when it comes to genetic modification of humans, even if it is done to prevent or treat disease.
Another interesting point is the potential use of CRISPR to edit the DNA of egg or sperm precursor cells to avoid some of the hurdles of editing embryos. This raises the question of how this approach would be implemented and regulated, as it involves altering the genetic material of potential future offspring before they are even conceived.
Overall, the article highlights the ongoing debate and ethical considerations around the use of CRISPR for genetic modification in humans, as well as the need for continued research and oversight to ensure that any such use is safe and ethical.

C The codon that is signaled
D The signaling sequence
2 What portion of the DNA is also known as a gene?
A The coding sections
B The non-coding sections
C The mRNA strand
D The polypeptide sequence
Answers
1. The correct answer is B.
2. The correct answer is A.
The codon sequence on the mRNA strand determines the amino acid sequence of the polypeptide.
The coding section is the portion of the DNA that is also known as a gene. Genes are the functional units of DNA that provide the instructions for making proteins. They are composed of coding cells, also known as exons, that contain the information needed to build the polypeptide, and non-coding sections, also known as introns, that do not.
The codon sequence on the mRNA strand is translated by the ribosome during protein synthesis. Each codon, which is a sequence of three nucleotides, corresponds to a specific amino acid. The ribosome reads the codon sequence on the mRNA strand and adds the corresponding amino acids to the growing polypeptide chain. This process is called translation.
In DNA, genetic information is encoded in the sequence of nucleotides, which are the building blocks of DNA. Genes are specific segments of DNA that contain the instructions for making a specific protein. These instructions are encoded in the sequence of nucleotides within the coding sections of the DNA, also known as exons. The non-coding sections, also known as introns, do not contain instructions for making proteins, but they play important roles in the regulation of gene expression.
