Question

question 14
due to_____, the 20,000 - 25,000 genes of the human genome seem to encode as many as 120,000 different expressed mrnas.
o independent assortment
o recombination
o alternative splicing
o mutations

Explanation:

Alternative splicing is a process in which different combinations of exons within a gene are joined together during mRNA processing. This allows a single gene to produce multiple different mRNA transcripts. Mutations are changes in the DNA sequence. Recombination is the exchange of genetic material between chromosomes. Independent assortment is a principle in genetics related to the distribution of chromosomes during meiosis. Since the question is about how a relatively small number of genes (20,000 - 25,000) can encode a much larger number of mRNAs (up to 120,000), alternative splicing is the mechanism that best explains this phenomenon as it can generate multiple mRNA variants from one gene.

Answer:

alternative splicing
