How many codons are in 300 amino acids?

100 codons
Explanation: Each amino acid corresponds to codons; sequences of 3 base pairs. If you have 300 base pairs, you get 100 codons.

How many nucleotides would be required to code for a protein which is 300 amino acids in length?

Each codon stands for a specific amino acid, so if the message in mRNA is 900 nucleotides long, which corresponds to 300 codons, it will be translated into a chain of 300 amino acids.

How many amino acids could be coded for if a codon consisted of just two bases?

(a) How many amino acids could be coded for if a codon consisted of just two bases? 20 amino acids which is possible with a 2 base codon. Traditionally, a gene was defined as a section of DNA coding for a polypeptide.

Which type of amino acids form polypeptide chain in proteins?

Polypeptide chains are formed by dehydration between the amino group of a L-amino acid4 with the carboxyl group of another. One hundred or more amino acids are linked together with covalent peptide bonds in various specific sequences in the polypeptide chain with polypeptide chains combining to form a protein.

Are amino acids amphoteric?

Characteristics. Amino acids are amphoteric, which means they have acidic and basic tendencies. The carboxyl group is able to lose a proton and the amine group is able to accept a proton.

Why are codons 3 bases long?

The order of the “beads” is determined by the order of the codons carried by the messenger mRNA. So, the reason codons are three nucleotides long is because four is too many; two is not enough.

What does a long chain of amino acids create?

A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides.

How many nucleotides are in 300 amino acids?

The answer is C, 1800 nucleotides. Here’s why: Each amino acid residue in a polypeptide chain was coded for by 3 nucleotides called a codon. With this in mind, a polypeptide with 300 amino acids would need a minimum of 900 nucleotides to code for it (3 x 300 = 900).

How many different amino acid sequences are possible in a polypeptide 146 amino acids long?

(c) How many different amino acid sequences are possible in a polypeptide 146 amino acids long? (a) “multiple codons that code for the same amino acid” 4^3 =64 possible combinations.

How many amino acids could be specified if codons consisted?

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
