Answer:

Explanation:

The gal80 gene that blocks the ability of gal80 protein to interact with gal3p by the activation of gal80 gene.

In Saccharomyces cerevisiae, galactose turns on the allosteric sign transducer Gal3 protein (Gal3p), which in flip inactivates the repressor Gal80p, thereby activating the Gal4p-established transcriptional activation of GAL genetic switch.

If the GAL80 gene product can not engage with Gal3p, there may be no interplay with the Gal4p/Gal80p complicated and consequently no GAL1 transcription. In the absence of galactose, Gal80 binds to and inhibits the transcriptional activation domain (AD) of the GAL gene activator, Gal4, stopping GAL gene expression. Galactose triggers an affiliation among Gal3 and Gal80, relieving Gal80 inhibition of Gal4.

The correct level of aromatase activity at a temperature of 33°C is "100%". The correct option is (b).

This is because, during the TSP, the sex of the offspring is determined by the incubation temperature, which is within the range of the female-producing temperature, the developing embryos are more likely to become female.

Aromatase is an enzyme that converts testosterone into estradiol, a form of estrogen that is essential for female development. Therefore, it is expected that the level of aromatase activity would be high during this period to ensure the production of sufficient levels of estrogen for the development of female offspring.

Several studies have demonstrated that incubation temperature affects the activity of aromatase in reptiles. High incubation temperatures have been found to increase aromatase activity, while low temperatures reduce it.

Therefore, the correct answer is an option (b).

The US's faster rate of industrialization, coupled with its larger population, meant that it had a greater impact on its natural resources than Canada did.

There are various differences between the United States and Canada in terms of human influence on the biome and habitat by 1900. The main difference between the two countries in this context is the rate of industrialization and its impact on natural resources.

The following points explain this difference in more detail:

Canada's rate of industrialization was slower than that of the United States, which meant that it had less impact on the environment.

In Canada, logging, fishing, and agriculture were the primary industries, while in the United States, manufacturing and mining were dominant. This made the US's impact on its natural resources far more significant than that of Canada.The United States had a larger population than Canada, which led to more pressure on natural resources such as land and water.

The population of the US was around 76 million in 1900, compared to Canada's population of around 5 million.In conclusion, the main difference between the United States and Canada in terms of human influence on the biome and habitat by 1900 was the rate of industrialization.

The US's faster rate of industrialization, coupled with its larger population, meant that it had a greater impact on its natural resources than Canada did.

The process of translating mRNA into the chain of amino acids occurs on ribosomes in the cytoplasm of the cell, where mRNA is read.

Polypeptide chains are produced from the amino terminus to the carboxy terminus of all mRNAs, which are read in the 5' to 3' direction. According to universal genetic code, the mRNA specifies each amino acid by three bases (a codon).

During translation, the second critical stage in gene expression, the mRNA "reads" the genetic code, which links the DNA sequence to the amino acid sequence in proteins. Each codon in mRNA denotes a particular amino acid, and each codon is a trio of nucleotides.  As a result, the mRNA sequence serves as a template for the assembly of the chain of amino acids that constitutes a protein.

Explanation:

Though the parents have blood group A and B , still their son is of blood group and colorblind aswell is possible due to codominance.

What is codominance?

In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.

Red blood cells with blood type A have a specific antigen (class of protein) on their membrane. Red cells in type B blood have a unique antigen on their membrane, but neither is present in type O blood.

The type O gene is "recessive" because if you only have one copy of the O gene and one copy of the A gene, you will still have A antigens on your cell membranes. You must have two O parent cells in order to belong to group O. However, group O continues to be more prevalent merely because it is the ancestor form.

The X chromosome is where color blindness is most frequently inherited as a recessive trait. In genetics, this is referred to as X-linked recessive inheritance. As a result, men tend to be affected by the illness more frequently than women (8% male, 0.5% female). Males only get one X chromosome, thus even while the recessive trait is present, there isn't another X chromosome that would provide a dominant trait of normal color vision. On the other hand, most female offspring have a propensity to develop into what are known as "carriers," which are people who have the recessive gene (color blindness) as well as the dominant gene (normal color vision), resulting in the expression of the dominant feature.
