How are DNA RNA and proteins related?

Answer 1

The sequence of the bases on DNA is copied as a sequence of bases on RNA (messenger RNA). This is finally translatedinto a sequence of amino acids in the protein which determines the protein's structure and function.

Answer 2

RNA is the code that determines what proteins will be made. RNA attaches to a ribosome where the complementary tRNA anti-codon bonds to the RNA codon ( A bonds to U and G bonds to C). The codon or anti-codon is only three base pairs long. Every tRNA has one of twenty amino acids attached and so therefor every RNA codon codes for a specific amino acid. The amino acids attach to each other forming a chain then fold and twist to create different proteins.

Answer 3

DNA is not directly used to make proteins. Rather, it serves as the template from which an RNA message is transcribed. The RNA gets processed and a mature mRNA (messenger-RNA) moves from the nucleus to the cytoplasm of the cell.

RNA then is used in three ways to make proteins.

1) The mRNA from the nucleus provides the template which ribosomes read and translate into amino acids. The amino acid chain is the protein.

2) The amino acids are carried to the ribosome by tRNA (transfer RNA) molecules. Each tRNA carries one amino acid and a triplet of RNA bases. In order for the tRNA's amino acid to be included in the protein, its triplet needs to match the current triplet on the mRNA that is being translated by the ribosome.

3) Ribosomes themselves consist of proteins and rRNA (ribosomal RNA). In fact, rRNA makes up the most important section of the ribosome - the part that catalyses the chemical reaction for transferring amino acids from tRNAs to the protein-under-construction.

Answer 4

Proteins or amino acid are translated to RNA and RNA are transcripted to DNA.

Answer 5

The instructions for creating proteins are stored in DNA contained in the nucleus. This is then copied to mRNA (messenger RNA), which carries the instructions to ribosomes.

Answer 6

DNA is used as a template to synthesize RNA which helps bring the correct amino acids to synthesize proteins.

Answer 7

DNA makes RNA, and RNA makes proteins
