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?

Question: If 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) tRNAs

(d) Ribosomes

The correct answer is (a) Adenine Molecules.

Explanation:

Transcription can be explain as transfer of genetic information from DNA to RNA. During transcription, mRNA is produced as copy of gene to allow the genetic information go out of nucleus to form protein. Adenine molecules would not be needed for this process. Actually, It is formed when adenine is attached to a ribose ring and one of the bases used in forming  nucleotides of the DNA and RNA not in transcription.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
