In order to add nucleotides to an expanding strand of RNA, RNA polymerase unwinds the double helix.

RNA Pol I: It synthesizes the pre-rRNA subunits that make up ribosomes, which is one of many forms of RNA Pol enzymes found in eukaryotes. RNA Pol II: It creates mRNA, snRNA, and microRNA precursors. RNA Pol III: It produces short RNAs, other rRNA precursors, and tRNA.

According to the DNA wrapping model of transcription, DNA bending and wrapping around RNA polymerase results in the DNA helix being unwound at the enzyme's catalytic site, which induces strand separation both before and during transcript elongation.

Answer:

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with an infinitely hot, infinitely dense singularity, then inflated — first at unimaginable speed, and then at a more measurable rate — over the next 13.8 billion years to the cosmos that we know today.

Because current instruments don't allow astronomers to literally peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.

While the majority of the astronomical community accepts the theory, there are some theorists who have alternative explanations besides the Big Bang — such as eternal inflation or an oscillating universe..

The global circulation patterns, specifically the North Pacific High in summer and the westerlies in winter, greatly influence the climate of Southern California.

In Southern California, the global circulation patterns have a significant influence on the climate, with variations between the summer and winter seasons. Here's how it affects the weather:

1. Summer Circulation:

During the summer, the region is influenced by the North Pacific High-pressure system, also known as the Pacific High. This semi-permanent subtropical high-pressure system develops over the northeastern Pacific Ocean, off the California coast. The Pacific High brings about stable, warm, and dry conditions to Southern California during the summer months. The clockwise circulation around the high-pressure system leads to the development of offshore winds, commonly known as Santa Ana winds, which can further amplify dry and warm conditions.

2. Summer Weather:

Due to the influence of the Pacific High, Southern California experiences hot and dry summers. The high-pressure system blocks the intrusion of marine air from the nearby ocean, resulting in limited cloud cover and minimal rainfall. The dry conditions, combined with the offshore winds, contribute to increased fire risk and elevated temperatures in inland areas.

3. Winter Circulation:

In winter, Southern California is influenced by the westerlies, which are prevailing winds that blow from west to east. The westerlies are part of the mid-latitude circulation patterns and are responsible for the movement of weather systems across the region. The jet stream, a high-speed river of air in the upper atmosphere, plays a significant role in steering storm systems during the winter months.

4. Winter Weather:

The westerlies and the associated jet stream play a crucial role in bringing precipitation to Southern California during the winter season. Storm systems from the Pacific Ocean travel eastward along the jet stream, reaching the region and bringing rainfall. The intensity and frequency of storms can vary from year to year, impacting the amount of precipitation received. These winter storms are crucial for replenishing water resources and contributing to the overall seasonal rainfall in the area.

Overall, the global circulation patterns, specifically the North Pacific High in summer and the westerlies in winter, greatly influence the climate of Southern California. Understanding these circulation patterns and their seasonal variations helps in predicting and understanding the region's weather patterns, including temperature, precipitation, and wind conditions.

Answer:

The nucleic acid DNA is an organic compound. DNA is made up of repeating subunits called nucleotides . Each DNA molecule consists of 2 long chains of nucleotides. A DNA nucleotide has three parts: a sugar molecule called deoxyribose ; a phosphate group, and a molecule that is referred to as a nitrogenous base because it contains nitrogen atoms. The deoxyribose sugar and the phosphate group are identical in all DNA nucleotides. However, the nitrogenous base may be any one of 4 different kinds. The four nitrogenous bases found in DNA nucleotides are adenine, thymine, cytosine, and guanine. The two strands of a DNA molecule are held together by hydrogen bonds.

Water is attracted to the sides of a glass cylinder is an example of cohesion.

Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you're demonstrating strong cohesion.

Cohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress.

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

1. In gel electrophoresis, DNA strands are sorted based on their size and charge. The gel matrix creates a barrier that impedes the movement of larger molecules, allowing smaller molecules to move faster and migrate farther from the starting point. The electric field applied to the gel causes the negatively charged DNA strands to move towards the positive electrode.

2. The fact that the DNA strands move towards the positive charge indicates that the strands themselves are negatively charged. The negatively charged DNA molecules are attracted to the positive electrode, allowing them to be sorted based on their size and charge during gel electrophoresis.

3. Gel electrophoresis involves placing the DNA mixture in a well at one end of a porous gel matrix and applying an electric field to the gel. The negatively charged DNA molecules move towards the positive electrode, with smaller fragments moving farther than larger fragments. As the DNA fragments move through the gel, they become sorted according to their size, with smaller fragments migrating farther from the starting point than larger fragments.

4. "Agarose chase" or simply "gel" are common slang terms used by scientists to refer to gel electrophoresis.

When conducting scientific experiments, researchers develop hypotheses to guide experimental design. A hypothesis is a suggested explanation that is both testable and falsifiable. You must be able to test your hypothesis, and it must be possible to prove your hypothesis true or false.

When it is said that the cell membrane has a difference in electrical charge between its inside and the outside, this means the membrane is Polarized.

The cell membrane is said to be polarized because there is a potential difference across the cell membrane. When the membrane potential becomes more positive than the resting potential, the membrane is said to be depolarized. When the membrane potential becomes more positive than the resting potential, the cell membrane is said to be depolarized.

When the membrane potential becomes more negative than the resting potential, the membrane is said to be hyperpolarized.

The resting membrane potential is determined by the uneven distribution of ions (charged particles) between the inside and outside of the cell and the differential permeability of the membrane to different types of ions.

The Y chromosome contains the SRY gene, which initiates embryonic development as a male. Other genes required for normal sperm production can be found on the Y chromosomes of humans and other mammals. There are, however, exceptions.

The SRY gene on the Y chromosome is a "male-determining gene" that causes testes to form in the embryo and results in the development of external and internal male genitalia. If the SRY gene is mutated, the embryo will develop female genitalia despite having XY chromosomes.

The Y chromosome is the one size of the X chromosome and contains approximately 55 genes, whereas the X chromosome contains approximately 900 genes.

Our total body weight accounts for about 7 to 8 % of blood. Blood is a mixture of around 55 percent plasma and 45 percent blood cells. Blood running through the veins, arteries and capillaries is called whole blood.

How does the blood change as it flows through the respiratory system?

Blood circulatory system, also called the cardiovascular system, delivers oxygen and nutrients to all the cells of the body.

The respiratory system consists of the respiratory passage and respiratory organ, that is the lungs.

Blood is carried to the lungs through the pulmonary arteries where it picks up oxygen. The blood then leaves the lungs and returns to the heart via the pulmonary vein. It then enters the left atrium. The blood then drops into the left ventricle through the mitral valve.

Transport of gases also occurs through blood.

For exchange or oxygenation, the deoxygenated blood is transported to the lungs from heart. Carbon dioxide is exchanged with oxygen as the blood flows through the respiratory system. For further circulation to various body parts, oxygenated blood is then transported to the heart.

Some amount of gases get dissolved in the blood plasma and get transported, whereas some amount of them is transported in the bound state.

So therefore, CO2 and oxygen bind with hemoglobin in RBC.
