mRNA and Protein Synthesis Concepts Pret Test

Front

What are amino acids?

Back

The building blocks (monomers) of protein.

Front

What is the function of mRNA?

Back

To transmit the code for making proteins from DNA to the site of protein synthesis and to carry the information necessary to make a protein from the nucleus to the ribosome.

Front

What happens at the ribosome?

Back

Protein synthesis occurs, where mRNA codons and their complementary tRNA anti-codons match up, and amino acids are joined together by peptide bonds to make a polypeptide (protein).

Front

What is the job of mRNA?

Back

To serve as instructions for making proteins at the ribosome.

Front

What is translation?

Back

The making of a protein using the codons on mRNA as instructions.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches its anticodon with the corresponding codon on the mRNA.

Front

What is a codon?

Back

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

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where mRNA is translated into protein, facilitating the binding of tRNA and the formation of peptide bonds.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of making mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is a peptide bond?

Back

A covalent bond that links amino acids together in a protein.
