Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of ribosomes in cells?

Back

Ribosomes are the sites of protein synthesis.

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 a gene and a chromosome?

Back

A gene is a segment of DNA that codes for a protein, while a chromosome is a structure that contains many genes.

Front

What is the function of enzymes in biological reactions?
