BIOXII06: MOLECULAR BASIS OF INHERITANCE

342727 The salient features of genetic code are as follows:
i. The codon is triplet. 61 codons code for amino acids and 3 codons do not code for any amino acids, hence they functionas stop codons.
ii. One codon codes for only one amino acid, hence, it is ambiguous and specific.
iii. Some amino acids are coded by more than one codon, hence the code is generate.
iv. The codon is read in mRNA in a contiguous fashion. There are no punctuations.
v. AUG has dual functions. It codes for Methionine (met), and it also act as initiator codon.
Select the incorrect options

1 i & iii are incorrect
2 i, ii & iii are incorrect
3 i, ii ,iii & iv are incorrect
4 ii & iii are incorrect

342728 If there are 999 bases in an RNA that codes for a protein with 333 amino acids, and the base at position 901 is deleted such that the length of the RNA becomes 998 bases, how many codons will be altered?

BIOXII06: MOLECULAR BASIS OF INHERITANCE

342729 A segment of DNA has the triplet base sequence. AAG, GAC, AGC, CGC, ACA and AAA. Due to mutation the first base only got deleted. Then the likely effect of this on the coding of DNA segment is that

1 There will be complete change in the types and sequence of amino acids
2 Polypeptide will have one amino acid less
3 There will be no change in polypeptide chain formed
4 The first amino acid will be different

1 UUA - valine
2 AAA - lysine
3 AUG - cysteine
4 CCC - alanine
