Front

What is the function of messenger RNA (mRNA)?

Back

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

Front

Back

The process by which a DNA molecule makes a copy of itself.

Front

What are codons?

Back

Sequences of three nucleotides in mRNA that specify an amino acid.

Front

What is the role of transfer RNA (tRNA) in protein synthesis?

Back

To bring amino acids to the ribosome during translation.

Front

What is the significance of complementary base pairing in DNA?

Back

It ensures accurate replication and transcription of genetic information.
