A typical eukaryote protein might be amino acids long and could be produced in less than _ in translation.

a. 50 ... 5 minutes

b. 50,000 ... 5 hours

c. 5 ... 5 seconds

d. 400 ... 2 minutes

e. 4,000 ... 4 minutes

Adv.

Answer:

Translation is the process of synthesizing a protein by using mRNA as template. The building blocks of proteins are the amino acids. The site of translation is ribosome. The ribosome can add 4 amino acids to the growing polypeptide chain per second. Thus, a typical eukaryote protein of 400 amino acids long can be produced in less than 2 minutes.

Hence, the correct option is (d) 400…2 minutes.
