How many codons are needed to code 50 amino acids?
150 codons
Hence, there will be minimum 150 codons for 50 amino acids. Cistron is a part of mRNA that codes for a particular amino acids including a start codon and a stop codon.
How many nucleotides are needed to encode a protein 50 amino acids long?
The genetic code is the relation between the sequence of bases in DNA (or its RNA transcripts) and the sequence of amino acids in proteins. Experiments by Francis Crick, Sydney Brenner, and others established the following features of the genetic code by 1961: 1. Three nucleotides encode an amino acid.
How many codons are needed for 30 amino acids?
Three codons are needed to specify three amino acids. Codons can be described as messengers that are located on the messenger RNA (mRNA).

How many codons are in an amino acid?
64 codons
Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis. Because there are only 20 different amino acids but 64 possible codons, most amino acids are indicated by more than one codon.
How many codons would be needed to code for a protein that has 45 amino acids?
(d) 45, (e) 75? (a) 1, because 4^1 = 4 codons, which is more than enough to specify 2 different amino acids.
How many nucleotides are needed to code for a protein with 100 amino acids?
Answer: Every three nucleotides in an mRNA specifies the addition of one amino acid in a protein. Each three-letter “word” (combination of nucleotides) is called a codon. Therefore, amino acids are coded by a series of three-letter “words” – a 300 nucleotide mRNA will code for a 100 amino acid protein.
How many codons are needed for an amino acid?
three
Figure 1: In mRNA, three-nucleotide units called codons dictate a particular amino acid.
Why do only 61 of the 64 codons code for an amino acid?
Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis. Because there are only 20 different amino acids but 64 possible codons, most amino acids are indicated by more than one codon.
How does a codon code for an amino acid?
Codons are made up of any triplet combination of the four nitrogenous bases adenine (A), guanine (G), cytosine (C), or uracil (U). The other 18 amino acids are coded for by two to six codons. Because most of the 20 amino acids are coded for by more than one codon, the genetic code is called degenerate.
How are the Order of codons determined?
Also, the order of codons in the gene specifies the order of amino acids in the protein. It may require anywhere from 100 to 1,000 codons (300 to 2,000 nucleotides) to specify a given protein. Each gene also has codons to designate the beginning ( start codon) and end ( stop codon) of the gene.
How many bases are needed to code for amino acids?
How many bases are needed to make 3 amino acids? Explanation: Each amino acid is coded by 3 bases , and so three amino acids would need: 3 ⋅ 3 =9 bases . 35 Related Question Answers Found
How many base codes are there for one amino acid?
Four nitrogenous bases and three nucleotides together form a triplet codon which codes for one amino acid. Thus, the number of possible amino acids would be 4 x 4 x 4 = 64.
How many nucleotides make a codon?
A codon is like a three letter word in the language of molecular biology. Three nucleotides of RNA are one codon. Since codons do not overlap, a sequence of 12 nucleotides will contain 4 codons.
