What else can I help you with?
If a DNA sequence consists of 12 nucleotides how many mRNA codons will there be?
A DNA sequence consisting of 12 nucleotides will produce 4 mRNA codons. This is because each codon is made up of 3 nucleotides, so you can divide the total number of nucleotides (12) by the number of nucleotides per codon (3), resulting in 12 ÷ 3 = 4 codons.
How many bases are needed to specify an mRNA codon?
3 bases are needed to specify an mRNA codon.
How many MRNA nucleotides make up a codon?
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.
If there are 12 nucleotides how many mrna codons are there?
If there are 12 nucleotides, the number of mRNA codons can be calculated by dividing the total number of nucleotides by 3, since each codon consists of 3 nucleotides. Therefore, with 12 nucleotides, there would be 12 / 3 = 4 codons.
How many amino acids does each condon code for?
No they are not. For a codon, there are 4^3 = 64 codon combinations, but only 20 [common] amino acids. The 4 represents the 4 nitrogenous bases, and the ^3 represents the arrangement into a codon (3 bp). An example of an amino acid that is specified by more than one amino acid is Alanine, which is specified by any of the following combinations: GUU, GUC, GUA, GUG. Because most amino acids have more than one codon, the genetic code is called "degenerate".
How many nucleotides are in a codon?
A three-nucleotide sequence makes up a codon.
How many letters make up a codon?
A codon is made up of three nucleotides, or three letters (A, C, G, or T) in the genetic code. Each codon codes for a specific amino acid in a protein sequence.
How many nucleotides are required to encode one amino acid?
A codon, or a 3-base code is required to code for one amino acid.
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 nucleotides are needed to specify one codon?
three.
How many different codon combinations are there in the genetic code?
There are 64 different codon combinations in the genetic code.
How many codons are there in an mRNA with 75 nucleotides?
Every codon is three nucleotide pairs, so you would have 25 codons.
A polypeptide found in the cytoplasm of a cell contains 12 amino acids How many nucleotides would be required in the mRNA for this polypeptide to be translated?
Since each amino acid is coded for by a specific triplet of nucleotides (codon), and there is a start codon and a stop codon, we need 15 nucleotides in the mRNA (3 nucleotides for each amino acid + 3 for start codon + 3 for stop codon).
How many bases on a strand of mRNA code for one amino acid?
3 nucleotides
How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?
A minimum of 600 nucleotides is necessary to code for a polypeptide that is 200 amino acids long because each amino acid is coded for by a sequence of three nucleotides in mRNA. This is due to the genetic code being triplet, where every three nucleotides represent one amino acid.
If a DNA sequence consists of 12 nucleotides how many mRNA codons will there be?
A DNA sequence consisting of 12 nucleotides will produce 4 mRNA codons. This is because each codon is made up of 3 nucleotides, so you can divide the total number of nucleotides (12) by the number of nucleotides per codon (3), resulting in 12 ÷ 3 = 4 codons.
How many different nucleotides would have to be present in a codon to code for 14 different amino acids?
2
