Protein Synthesis & Mutations

Front

What is a silent mutation?

Back

A silent mutation is a type of mutation that does not change the amino acid sequence of the final polypeptide.

Front

What does each codon in messenger RNA specify?

Back

Each codon in messenger RNA specifies a particular amino acid.

Front

How is the DNA sequence GCTATA transcribed to mRNA?

Back

The DNA sequence GCTATA is transcribed to mRNA as CGAUAU.

Front

What amino acid is represented by the mRNA codon AUG?

Back

The mRNA codon AUG represents the amino acid Methionine.

Front

What type of mutation involves the replacement of one nucleotide with another?

Back

This type of mutation is called a substitution mutation.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template for translating the genetic code into a sequence of amino acids during protein synthesis.

Front

What is the process of translating mRNA into a protein called?

Back

The process of translating mRNA into a protein is called translation.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

What is the significance of the start codon in protein synthesis?

Back

The start codon (AUG) signals the beginning of translation and codes for Methionine.

Front

What are the three types of mutations?

Back

The three types of mutations are substitution, insertion, and deletion.
