AS Biology Quarterly Exam Review

Front

What is the sequence of amino acids coded by the mRNA codons CGG GCC CCG CGG?

Back

Ala-Arg-Gly-Ala

Front

What type of fatty acid is described as unsaturated with 18 carbon atoms?

Back

Fatty acid 2 of the 56:4 triglyceride.

Front

What is the effect of a mutation that prevents the formation of disulfide bonds in a protein?

Back

The protein will lose its tertiary structure and become nonfunctional.

Front

What does the process of translation require?

Back

mRNA, ribosomes, amino acids and tRNA.

Front

What are the bonds that join amino acids called?

Back

Peptide Bonds.

Front

Define translation in the context of protein synthesis.

Back

Translation is the process by which ribosomes synthesize proteins using mRNA as a template.

Front

What is the role of tRNA in translation?

Back

tRNA transports specific amino acids to the ribosome during protein synthesis.

Front

What is the primary structure of a protein?

Back

The primary structure is the linear sequence of amino acids in a polypeptide chain.

Front

What is the difference between saturated and unsaturated fatty acids?

Back

Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds.

Front

What is the significance of disulfide bonds in protein structure?

Back

Disulfide bonds help stabilize the tertiary structure of proteins.
