<span>The protocell's fatty acid membrane allows chemical compounds, including the building blocks of DNA, to enter into the cell without the assistance of the protein channels and pumps required by today's highly developed cell membranes</span>
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.
DNA acts as a sort of set of instructions for building an organism.
In that way, different types of organisms--plants, animals, bacteria, etc.--can all be differentiated through their DNA because it is directly linked to how they function.
Exchanging oxygen and carbondioxide between air and lungs because it just involves breathing system but everything else involves hormones.........
