Question

1) Answer True or False for each questions

a) Each amino acid is coded by a single combination of three nucleotides. (T/F)

b) Several amino acids can be coded by the same combination of three nucleotides. (T/F)

c) Non-conventional nucleotides in anticodon can correspond to the first position of codon. (T/F)

2) For reading frames (potentially) for each RNA sequence, is it 1? I'm not sure if its one or three.

Answer 1

ANSWER 1:-)

A) TRUE

Each amino acids are coded by single combination of three nucleotides called codon.There are 64 codon combinations and out of these 61 codons code for amino acids and the rest are stop codons UAA, UAG AND UGA.

B) FALSE

There are 61 possible codons that code for aimo acids.

C) The statement is true.

2) There are 6 ways in which DNA sequence can be read, Three reading frames in one direction and three reading frames in opposite direction.

Basically three frames are there.
