Question

Which type of mutation helped lead to the understanding that the genetic code is based on triplets?

1) Point mutation
2) Frameshift mutation
3) Silent mutation
4) Chromosomal mutation

Answer 1

Frameshift mutation is the type of mutation that helped lead to the understanding that the genetic code is based on triplets.

Step-by-step explanation:

The type of mutation that helped lead to the understanding that the genetic code is based on triplets is frameshift mutation. Frameshift mutations occur when bases are either inserted or deleted in a DNA sequence, causing a shift in the reading frame. This shift changes the way the codons are read, resulting in a completely different sequence of amino acids.
