Question

Select the wrong statement about gene.

• A. It is the unit of inheritance in living organisms.
• B. It involved in the whole metabolism of cells.
• C. It controls the transfer of hereditary characteristic from parents to offspring.
• D. Different combination of genes result different characteristic.

Answer 1

Answer: (B)

It involved in the whole metabolism of cells.

Gene is the segment of DNA which consist the heredity information and are characterized by as follows:

1. Genes are the units of heredity.
   
2. They are arranged in a linear fashion along chromosomes.
   
3. Recombination can occur both between and within genes.
   
4. Mutations in different genes required for a phenotype will complement each other in a diploid. This is the basis for genetic dissection of a pathway.
   
5. A gene is composed of a series of mutable sites that are also sites for recombination (now recognized as nucleotides).
   
6. One gene encodes one polypeptide.
   
7. The gene and the polypeptide are co-linear.
   
8. Single amino acids are specified by a set of three adjacent mutable sites; this set is called as a codon.

Thus, the correct answer is option B.
