The genetic code consists of the sequence of nitrogen bases in a polynucleotide chain of DNA or RNA. The bases are adenine (A), cytosine (C), guanine (G) and thymine (T) (or uracil U, in RNA). The four bases make up the "letters" of the genetic code.

What would happen, if in a gene encoding a polypeptide of 50 amino acids. \(25^{ {th }}\) codon (UAU) is mutated to UAA?
1 A polypeptide of 49 amino acids will be formed
2 A polypeptide of 25 amino acids will be formed
3 A polypeptide of 24 amino acids will be formed
4 Two polypeptides of 24 and 25 amino acids will be formed
Explanation:
If in a gene encoding a polypeptide of 50 amino acids, \(25^{ {th }}\) (UAC) is mutated to UAA, a polypeptide of 24 amino acids will be formed because UAA is a stop codon. Thus the resultant polypeptide will have 24 amino acids.

Which one of the following codons codes for the same information as UGC?
1 UGU
2 UGA
3 UAG
4 UGG
Explanation:
UGU codes for the same information as UGC. The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins by living cells. UGC and UGU codes for cystine amino acids.

A mature mRNA consists of 900 bases without any stop codon in between. Calculate the number of amino acids coded by this mRNA during translation.
1 299
2 450
3 900
4 300
Explanation:
A mature mRNA consists of 900 bases without any stop codon in between. Calculate the number of amino acids coded by this mRNA during translation will be 300 .
