Front

What is the function of mRNA in protein synthesis?

Back

To carry genetic information from DNA to the ribosome for protein production.

Front

What is the difference between a body cell and a gamete?

Back

Body cells are diploid (2n) and contain two sets of chromosomes, while gametes are haploid (n) and contain one set.

Front

What is the process of transcription?

Back

The process of copying a segment of DNA into RNA.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins from amino acids.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.
