Front

What is the function of DNA?

Back

To store and transmit genetic information.

Front

What are the two main types of nucleic acids?

Back

DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is a codon?

Back

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