The bases A,G,C,T (there is also U which substitutes for T in mRNA ) code for amino acids in groups of three. Three bases equal a codon.
So...there are several codons that produce a specific amino acid. Some amino acids are produced by a single 3 letter codon others have several 3 letter codons that produce the same amino acid. The number of codons that produce the named amino acids are in () with one example for each. As you can see there are no
repeats even in this abbreviated table. There are even 3 Stop codons.
Isoleucine (3) ATT Asparagine (2) AAT
Leucine (6) CTT Histadine (2) CAT
Valine (4) GTT Glutamic Acid (2) GAG
Phenylalanine (2) TTT Aspartic Acid (2) GAT
Methionine (1) ATG Lysine (2) AAA
Cysteine (2) TGT Arginine (6) AGG
Alanine (4) GCT Glycine (4) GGG
Proline (4) CCC Threonine (4) ACT
Serine (6) TCC Tyrosine (2) TAT
Tryptophan (1) TGG Glutamine (2) CAA
The nitrogenous, nucleic acid, [four] bases.
for mRNA, it takes 3 bases (A codon) to signal that a specific amino acid should be used. In this case you would need 100x3 = 300 bases.
those are A (adenine) paired with U (uracil) and vice versa, and C (cytosine) paired with G (guanine) and vice versa. T (thymine) is replace by U in RNA. mRNA carries the transcribed DNA out from the nucleus and go to ribosomes which is then 'translated' by matching the codon with anticodons attached in the tRNA which carry the correct amino acid.
The mRNA molecules carry the coded instructions for making proteins from the nucleus out to the ribosomes.
Transfer RNA brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins.
The properties of proteins are determined by the order in which different amino acids are joined together to produce polypeptides. The genetic code is read three letters at a time, so that each "word" of the coded message is three bases long.
mRNA
Transfer RNA comes in sets of three bases. You can arrange four different things into a large number different sets of three. Each combination of bases in Transfer RNA codes for a different amino acid.
It takes a set of three RNA bases to code for one amino acid. Since there are 4 different bases in RNA, there are 4 x 4 x 4 = 64 possible combinations. This is many more combinations than is necessary to code for 20 amino acids. The reason that there are more than 20 is that some combinations code for the same amino acid.
I'm not fully sure of your question, but if you are asking how many nucleotide bases are needed, then the answer is 3. Three nucleotide bases of DNA will translate to mRNA and these will code for tRNA anticodons, which carry one amino acid with them.
The function of messenger RNA is to carry copies of the instructions for assembling amino acids into proteins to the rest of the cell or, more specifically, to the ribosomes.

Yes, DNA carries the instructions for the correct sequence of nucleic acids in a protein. These instructions are encoded in the DNA molecule as a specific sequence of nucleotide bases (adenine, thymine, cytosine, and guanine). Through a process called transcription, the DNA sequence is transcribed into a messenger RNA (mRNA) molecule, which is then translated into a specific sequence of amino acids to form a protein.
All Cells carry, contain and control all sorts of proteins that are comprised completely from Amino acids.
