Front

Where is RNA made into protein?

Back

Ribosome.

Front

Why are insertion and deletion (frameshift) mutations so harmful?

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein function.

Front

What is the difference between a frameshift mutation and a point mutation?

Back

A frameshift mutation alters the reading frame of the genetic code, while a point mutation changes a single nucleotide.

Front

What is the central dogma of molecular biology?

Back
