In what way does the DNA code for proteins?

Answer 1

DNA has four letters, ACGT.

strings of these letters code for strings of amino acids-of which we have 20-these 20 amino acids make up all the proteins in our bodies.

DNA is the repository for all the data needed to make these amino acids. using RNA as an intermediate, each string of 3 DNA letters codes for one amino acid. long strings of amino acids hooked together make up proteins.

Answer 2

Short answer

DNA to RNA to protein

Slightly longer answer. The DNA template is transcribed by RNA polymerase. After some modification (in eukaryotes), namely intron splicing, 5' capping and 3' polyadenylation, the mature mRNA is transported to the cytosol. Once there ribosomes read the mRNA strand starting from a start codon (A codon is a tri-nucleotide sequence that corresponds to a particular amino acid), AUG which encodes methionine. The ribosome then travels along the strand, reading the codons and assembling the polypeptide. After the translation process is complete the protein is folded into its final form.

Answer 3

What you asked is the process of CENTRAL DOGMA in molecular biology , i.e. DNA-> RNA-> PROTEIN
(transcription) (translation)
First DNA transcribes mRNA from its tenplate strand through transcription process. The mRNA contains codons( 3 adjacent bases able to code for a particular amino acid/s).During Translation, the two ribosomal subunits( 60s & 40s for eukaryote & 50s & 30s for prokaryote) bind to the mRNA strand with some cofactors.When Ribosome decode the 1st codon ( most of the case it is AUG) the initial tRNA comes with the formylated amino acid of METHIONINE( f-met) and bind to the 16s rRNA of ribosome. Thus INITIATION COMPLEX is made.Then ribosome slide along the mRNA reading the codons and orders the tRNA to bring the encoded amino acid from the amino acid pool of the system. The tRNA brings the amino acid and the new amino acid is joined to the formar one by peptide bonding between them. Several amino acids linked by peptide bonds make a peptide chain. One or several peptides make a polypeptide and when folded to perform a specific functoin is known as protein.

Answer 4

Proteins are formed from amino acid subunits. Each triplet nucleic acid, (called a codon) in a the D.N.A. molecule codes for a specific amino acid. There are about 23 different amino acids that humans use for protein synthesis. Some of the codons are redundant. That is several amino acids are encoded by more than one specific codon. Several have eight different codons that code for that amino acid.
There all also stop codons that instruct the ribosomes to terminate the amino acid chain.

Answer 5

E. DNA codes for amino acids making use of three bases said as codons that are then transferred to RNA to take out of the nuclues on anticodons (which correspond to the codons) to ribosomes with the teachings for the formation of amino acids.

Answer 6

The DNA codes for RNA, and then the RNA is used as a template for making protiens, It sort of resembles a zipper with each little metal part being like one 3 letter codon maybe.

Answer 7

mRNA copies a strand of DNA then the each section of 3 mRNA elements code for a certain amino acid to be put together into a protein on the ribosome

Answer 8

Replication-> transcription->.translation
