An mRNA codon is 3 bases long and can contain 4 different bases (A, U, C and G).
Therefore there are 64 (4 X 4 X 4) different combinations.
Many of these will code for the same amino acid. For example; UCA, UCU, UCC and UCG all code for the amino acid Serine.

How many bases are needed to specify an mRNA codon?
3 bases are needed to specify an mRNA codon.
How many nucleotides a genetic codon carries?
Three nucleotides makes up each codon. The codons consist of combination of 4 differing nucleotides A,G,T, and C.
How many bases are in an anti-codon?
3 bases make up an anti-codon, 3 bases also make up a codon
What are the molecule codes for protein?
RNA
How many types of messenger RNA exist?
mRNA-moves from nucleus to cytoplasm to get transcribed by ribosome. rRNA- ribosomal RNA that is in splicesomes tRNA-transfer RNA that brings nucleotide bases to the mRNA strand being coded. tRNA matches its anticodon with the mRNA codon to make the polypeptide. Source: AP Biology student
How many tRNA nucleotides form an anitcodon that will attach to the mRNA codon?
The codon and the anticodon interact with each other via hydrogen bonding, hence both the codon and anticodon are made up of the same number of nucleotides, which is three.
How many bases on a strand of mRNA code for one amino acid?
3 nucleotides
How many nucleotides are in a codon?
A three-nucleotide sequence makes up a codon.
How many codons are there in an mRNA with 75 nucleotides?
Every codon is three nucleotide pairs, so you would have 25 codons.
How many bases are needed to specify an mRNA codon?
3 bases are needed to specify an mRNA codon.
How many nucleotides a genetic codon carries?
Three nucleotides makes up each codon. The codons consist of combination of 4 differing nucleotides A,G,T, and C.
How many bases do codons have?
Codons are made up of three bases/nucleotides in DNA or mRNA. Each codon encodes an amino acid or signifies a stop signal. Hope that helps!
How many nucleotides are needed to specify one codon?
three.
How many different mrna correspond to methionine?
Only one mRNA codon codes for Methionine - AUG.
How many amino acids make a codon?
One codon specifies a specific amino acid. However, more than one codon can code for the same amino acid. For example, the codon GUU codes for the specific amino acid valine; and the codons GUC, GUA, and GUG also code for valine.
How many bases are in an anti-codon?
3 bases make up an anti-codon, 3 bases also make up a codon
If an mRNA is made up of 60 bases how many codons does it contain and how many amino acid does it code for?
A codon is exactly three bases long, so an mRNA strand with 60 bases would contain 20 codons. The first codon will encode for methionine (this is called the "start" codon) and the last codon will be a "stop" codon, which does not encode for an amino acid. Thus, an mRNA strand of 60 bases will code for 19 amino acids. Keep in mind, it is possible for a stop codon to be anywhere on the mRNA strand, and when a stop codon reaches the ribosome, translation must stop. For example, if an mRNA strand contained 30 codons, and the 15th were a stop codon, the mRNA would only code for 14 amino acids and then be done. The other 15 codons would go untranslated.
