BIOXII06: MOLECULAR BASIS OF INHERITANCE
342855
Mutations are responsible for
1 Variation in organisms
2 Increasing the population rate
3 Maintaining the genetic continuity
4 Change in the environment
Explanation:
Mutation is sudden change in chemical structure of gene or altering position of chromosomes. They occur in somatic cells or gametes genetic mutation. Hence they lead to variation in organisms.

Which of the of the following statements about mutations is false?
1 Mutations are the source of new alleles for genes.
2 Mutations are random events and can happen in any cell at any time.
3 Organisms are able to create mutations to meet their specific needs.
4 Most mutations random tend to be harmful or have no effect on organisms.
Explanation:
The false statement about mutations is: (3) Organisms are able to create mutations to meet their specific needs. • Mutations are typically random events that can occur in any cell at any time. •Organisms do not intentionally create mutations to meet specific needs. Mutations are changes in the DNA sequence that can result from various factors, including errors during DNA replication, exposure to mutagens, or other natural processes. • While mutations can sometimes lead to the creation of new alleles for genes, most mutations tend to be either harmful or have no significant effect on organisms, and they are not purposefully generated by organisms to meet specific needs.

Which of the following function of DNA is necessary for the purpose of evolution?
1 Replication
2 Transmission of heredity
3 Mutation
4 Genetic expression
Explanation:
Mutation of DNA is necessary for the purpose of evolution, which causes variations.

In sickle cell anaemia, which amino acid modification occurs in the \(\beta\)-chain of amino acid?
1 Glutamate \(\rightarrow\) Valine
2 Tyrosine \(\rightarrow\) Valine
3 Tyrosine \(\rightarrow\) Glutamate
4 Valine \(\rightarrow\) Glutamate
Explanation:
Glutamic acid at the 6th position is changed to valine in beta chain in \(\mathrm{Hb}\) in sickle cell anaemia.
Mutation is sudden change in chemical structure of gene or altering position of chromosomes. They occur in somatic cells or gametes genetic mutation. Hence they lead to variation in organisms.
