Question

2. Classify each of the following statements as true (T) or false (F).
(a) _____ Each gene is responsible for only one visible trait.
(b) _____ Every trait is potentially affected by many genes.
(c) _____ The sequence of nucleotides in a gene specifies the sequence of amino acids in

a protein encoded by the gene.
(d) _____ There is one-to-one correspondence between the set of codons in the genetic

code and the set of amino acids encoded.

Answer 1

A single gene can be responsible for many traits.
hence given statement is FALSE

Yes, a particular trait can be affected by mutliple genes.
The statement is TRUE.

The sequence of nucleotides in gene specifies the sequence of mRNA, which
in turn specifies the amino acids in a protein.
The statement given is FALSE.

No. Multiple codons can give rise to same amino acid.
Example: CUU, CUC, CUA and CUG all can encode for leucine.
Hence the given statement is FALSE.
