What was marshall nirenberg and heinrich matthaei’s contribution to our current understanding of the genetic code?

Marshall Nirenberg and Heinrich Matthaei’s contribute to the current understanding of the genetic code by discovering the genetic code.

Further Explanation:

In TRANSLATION processes, mRNA is converted to protein. To translate mRNA it goes under A codon different processing before translating into protein mainly in eukaryotes. Transfer ribonucleic acid is a kind of RNA that helps in decoding a messenger RNA sequence into a specific protein. A codon is mainly present on the mRNA molecule and anti-codon is present on the tRNA molecule. A codon is actually a sequence of three nucleotides, which specifies to each amino acid in the chain of the polypeptide.

Marshall Nirenberg, a young biochemist at the National Institute of Arthritic and Metabolic Diseases, discovered the first "triplet"—a sequence of three bases of DNA that mainly codes for the twenty amino acids that help in serving the building blocks of the protein. Heinrich Matthaei and Marshall Nirenberg experimentally decode the first sixty-four codons present in our biological system.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
