Proteins encoded by genes within the same gene family are often said to have modularity if structure because:
a) they are affected by the same transposons
b) gene duplication always shifts protein module around
c) gene families arise from gene fusion, which creates two distinct modules
d) gene families usually have similar DNA sequences and therefore similar protein structure

Respuesta :

The proteins encoded by genes within the same gene family have modularity if structure because : ( D ) gene families usually have similar DNA sequences and therefore similar protein structure.

A gene family is a group of genes with a high level of similarity amongst them. the level of similarity present within the genes is because they are formed from the duplication of a single Parent gene, also a gene family shares a similar biochemical function. natural selection affects the increase or decrease of a gene family.

Gene families have similar DNA sequence because the genes found in a gene family is from an ancestral gene, also their protein structure is similar

Hence we can conclude that gene families usually have similar DNA sequences and therefore similar protein structure.
