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

What are four bases in RNA carry instruction for 20 different amino acids?
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.
A certain protein is made up of 100 amino acids What is the smallest number of bases in the messenger RNA molecule that is needed to carry the code for the synthesis of this protein?
The smallest number of bases needed would be 300 bases, as each amino acid is coded for by a sequence of three bases (codon) in mRNA. Therefore, 100 amino acids x 3 bases per codon = 300 bases in the mRNA molecule to code for the protein.
Which part of a DNA molecule carries the genetic instructions that are unique th the sugar phosphate backbone or the nitrogen containing bases?
The nitrogen-containing bases, which are adenine, thymine, guanine, and cytosine, carry the genetic instructions in a DNA molecule. These bases form the rungs of the DNA ladder. The sugar-phosphate backbone of the DNA molecule provides structural support.
It became apparent to Watson and crick after completion of their model that DNA molecule could carry a vast amount of hereditry information in what?
Watson and Crick realized that the DNA molecule could carry a vast amount of hereditary information in its sequence of nucleotide bases. They discovered that the specific arrangement of these bases along the DNA strand encoded the genetic instructions necessary for the development and functioning of living organisms.
Some organisms do not have a DNA or RNA true or false?
False. All living organisms have either DNA or RNA (or both) as their genetic material. These molecules carry the instructions for the development, functioning, growth, and reproduction of living organisms.
What carry instructions for making proteins?
mRNA
How can only four bases in rna carry intructions for 20 different amino acids?
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.
How can only four bases in RNA carry instructions for 20 different amino acids?
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.
How can only 4 bases in rna carry instructions for 20 amino acids?
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.

How many bases are needed to specifiy an 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.
What is the function of the messenger rna?
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.

Does DNA code carry instructions the correct sequence of nucleic acids in a protein?
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.
What Cells carry amino acids?
All Cells carry, contain and control all sorts of proteins that are comprised completely from Amino acids.
