Chromosomal mutations

If break occurs within a gene the function might be lost • Broken ands do not have telomeres that prevent degradation but the broken end is “sticky” and can adhere to other broke ...

Quiz 3 Friday Answer Key
... Show all work for partial credit. 1. a) What are the likely effects of a single base pair insertion in the DNA near the N-terminus of a gene? Frameshift will probably result in early stop codon - no/very tiny protein. More severe effect on protein sequence than insertion near C-terminus. b) What if ...

Epistasis
Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually. It was originally a concept from genetics but is now used in biochemistry, population genetics, computational biology and evolutionary biology. It arises due to interactions, either between genes, or within them leading to non-additive effects. Epistasis has a large influence on the shape of evolutionary landscapes which leads to profound consequences for evolution and evolvability of traits.
