Question

Diseases caused by expanding nucleotide repeats may become more severe in each generation, which may account for the process known as:

A) Anticipation
B) Translocation
C) Polymorphism
D) Epistasis

Answer 1

Expanding nucleotide repeats can lead to diseases that become more severe in each generation, a process known as anticipation. This is often seen in diseases caused by trinucleotide repeat expansions, such as Huntington's disease.

Step-by-step explanation:

Expanding nucleotide repeats can lead to diseases that become more severe in each generation, a process known as anticipation. Anticipation refers to the phenomenon where the symptoms of a genetic disorder become more pronounced or appear at an earlier age with each successive generation. This is often seen in diseases caused by trinucleotide repeat expansions, such as Huntington's disease.
