A cell biologist found that two different proteins with different structures were translated from two different mRNAs. These mRN

As, however, were transcribed from the same gene in the cell nucleus. Which mechanism below could best account for this?

Answer:

Alternative splicing

Explanation:

One gene can lead to multiple proteins by the alternative splicing of the mRNA. The alternative splicing is the most common process that contributes to protein diversity at a pot-transcriptional level. This process is carried out by different combinations of including or excluding exons of the mRNA, obtaining proteins that differ in their amino acids sequence, consequently having different biological functions.

Hi

Before answering this question, we need to understand first that what a mutation is. <em>A mutation basically is a change in the DNA or genetic sequence of an organism that can significantly affect or not affect the function of a specific gene in organism. </em>

Now coming towards the question, yes ofcourse it is possible that a Norwar rats population carries a different genetic mutation than a population os same rats in Africa or any other region, Why? Because sometimes environmental factors of a certain area can cause the population of a region to undergo mutation (For example harsh UV rays) and the other population donot contains that mutation. This will cause a slight change in the genetic makeup of the population of rats of Norther America. However, if the changes in genetic makeup continues to happen in North American Norway rats, a time will come when they will be genetically very different from same rats in Africa and in this way they will become a separate or different specie, this phenomenon is called speciation.

Hope it helps!

In a population of heffalumps, there is a single gene that controls the presence of hair. The H allele, which is a complete domi

<h2>Frequency of allele </h2>

Explanation:

Hardy Weinberg Equilibrium is used to calculate the allelic as well as genotypic frequency

Allelic frequency of dominant and recessive allele is represented by p and q respectively whereas genotypic frequency of dominant genotype is represented by p2 and q2 respectively

Given:

H allele (p) = hairy heffalump (dominant)

h allele (q) = hairless heffalump (recessive)

36% of heffalump population is hairless represents the % of recessive genotype, hh (q2) =36%

Calculation of frequency of the h allele (q) :

Frequency of genotype hh (q2) will be: 36/100=0.36 or 0.6*0.6

Frequency of h allele (q) will be 0.6
