Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits or characteristics.

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to variations in traits.

What is the significance of the double helix structure of DNA?

Back

The double helix structure of DNA allows for the stable storage of genetic information and the accurate replication of DNA during cell division.

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating messenger RNA (mRNA) into amino acid sequences.
