Which of the following is NOT a function of proteins?

A) transport, e.g. haemoglobin which transports O2 in the blood

B) storage, e.g. casein which supplies the nucleotides needed for baby mammals

C) catalysts, e.g. the digestive enzyme pepsin

D) structural support, e.g. collagen in connective tissue

E) defence against foreign substances, e.g. antibodies to combat foreign invaders

Expert Solution

B) storage, e.g. casein which supplies the nucleotides needed for baby mammals.

Casein is the chief milk protein. It does not supply the nucleotides needed for baby mammals. Casein supplies amino acids, carbohydrates, calcium and phosphorus.

Which of the following is not a characteristic of transcriptional activator proteins?

Which of the following is not a characteristic of transcriptional activator proteins? They can interact with other components of the transcriptional apparatus. They are capable of binding DNA at a consensus sequence in the protein-coding part of the gene. They contain one or more DNA-binding motifs. They are capable of binding DNA at a consensus sequence of a regulatory promoter. They can influence the rate of transcription.
