How many codons would be possible in a triplet code if only three bases a C and U were used?

To calculate the number of possible codons of a triplet code if only three bases are used, the following equation can be used: 3n, where n is the number of nucleotides within the codon. So, the number of possible codons is equal to 3^3, or 27 possible codons.

How many codons are possible from 3 bases?

64
However, a triplet code produces 64 (43 = 64) possible combinations, or codons.

What would be the effect if one of the bases were deleted?

What would be the effect if one of the bases were deleted in the very first mRNA codon? The deletion or addition of a nucleotide would change the rest of the sequence. The wrong protein or a nonfunctional protein would be made.

Why do we require 3 RNA bases to code for one amino acid?

The more bases there are per codon the more information you can code for. There are only 22 different amino acids, in consequence we need minimum 3 bases per codon.

How many different RNA sequences can encode the amino acid sequence Met Ala Leu Arg Cys?

Therefore, the number of potential sequences is the product of the number of different potential codons for this tripeptide, which gives us a total of (1 × 6 × 6 × 3) = 108 different mRNA sequences that can code for the tripeptide Met-Leu-Arg.

How many codons would be needed in an RNA to make a protein that has 50 amino acids?

50 because 150 nucleotides gives 50 codons, and each codon makes one amino acid – so 50 amino acids.

How many DNA or RNA nucleotides are in a codon?

three DNA
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids.

Why must a codon consists of three bases instead of two?

DNA is comprised of 4 different nucleotides (A, C, T, and G), whereas proteins are made of 20 amino acids. Codons are nucleotide triplets that encode for amino acids. Thus, in order for the 4 nucleotides to account for all 20 amino acids, a minimum of 3 base pairs are required.

What would happen if there was a substitution of one base for another in one Mrna codon?

Although a base substitution alters only a single codon in a gene, it can still have a significant impact on protein production. In fact, depending on the nature of the codon change, base substitutions can lead to three different subcategories of mutations.

What would be the effect of an addition or deletion of one of the bases in a codon?

When a nucleotide is wrongly inserted or deleted from a codon, the affects can be drastic. Called a frameshift mutation, an insertion or deletion can affect every codon in a particular genetic sequence by throwing the entire three by three codon structure out of whack.

How many different mRNA sequences could encode the amino acid sequence met Tyr Val His TRP?

From the table, we can see that the amino acid His has two potential codons, while the amino acids Met and Trp each have only one potential codon. Therefore, there are two different mRNA nucleotide sequences that could encode for the tripeptide.
