It is possible to synthesize proteins in vitro (in a test tube) without the use of living cells. If starting from a mature mRNA transcript, which of the following components would not be needed to do this?
A. Adenine molecules.
B. Amino acids.
C. Ribosomes.

C (Ribosomes)

Explanation:

Ideally, protein synthesis is a process that occurs in living cells involving the transcription of DNA into mRNA molecule and a subsequent translation of the mRNA into amino acids, which encodes proteins.

However, in vitro (test tube) production of proteins can be done outside living cells, which means that the site of protein synthesis in living cells called RIBOSOME is not needed for the in vitro procedure.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
