Studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.
Diano4ka-milaya [45]

The question is incomplete. The correct question is as following:

__________ studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.

Answer:

Marshall Nirenberg and Heinrich Matthaei

Explanation:

Marshall Nirenberg and Heinrich Matthaei are two biochemist and geneticist who studied the functional importance of RNA in the process of translation (protein synthesis) experimentally in E.Coli.

Nirenberg and Matthaei discovered the first codon out of 64 codons present in RNA and they successfully performed translation (protein synthesis) in E.coli in a test tube. They decoded the first codon UUU (phenylalanine) by using synthetic RNA having only uracil nucleotides in a E.Coli and later they decoded further codons.

So, the correct answer is  Marshall Nirenberg and Heinrich Matthaei.

Which of the following statements regarding membrane protein function is FALSE?A) membrane proteins serves as enzymesB) membrane
Sever21 [200]

Answer: D)

Membrane proteins produce phospholids

Explanation:

Membrane proteins in the mitochondria do more than just generate cellular energy. The proteins in the membranes of the mitochondria are complex machines in the nanoworld that mediate the oxygen-coupled generation of energy in cells. Their role in this process is not yet understood in detail.

Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
