Front

What type of mutation is represented by the DNA segments: TTACGCATC (original) and TTACGCAAC (mutated)?

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion mutations add one or more nucleotides to the DNA sequence, while deletion mutations remove nucleotides.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, coded for by sequences of nucleotides in DNA.
