DNA Rep/Transcription/Translation Review

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What are the three main components of a nucleotide?

Back

Sugar, Phosphate, and Nitrogenous Base.

Front

Where does transcription occur in eukaryotic cells?

Back

Transcription occurs in the nucleus.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation, matching them to the codons on the mRNA.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that specify a particular amino acid.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins by linking amino acids together.

Front

What are the stop codons in mRNA?

Back

The stop codons are UAA, UAG, and UGA, which signal the termination of protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is the significance of the genetic code?

Back

The genetic code is the set of rules by which information encoded in mRNA is translated into proteins.
