DNA vs. RNA and Protein Synthesis

Front

What is the primary function of DNA?

Back

DNA stores and transmits genetic information.

Front

Where is DNA primarily located in a cell?

Back

DNA is primarily located in the nucleus.

Front

What process produces mRNA from DNA?

Back

Transcription.

Front

Where does transcription occur in a eukaryotic cell?

Back

In the nucleus.

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 are codons?

Back

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

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches them to the codons in mRNA.

Front

What are anti-codons?

Back

Anti-codons are sequences of three nucleotides on tRNA that are complementary to the codons on mRNA.

Front

What is the genetic code?

Back

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

Front

Can a single amino acid be specified by more than one codon?

Back

Yes, some amino acids are specified by multiple codons.
