Which of the following statements are true about mutations O
Solution
There are known hot spots in DNA where mutations are more than 100 times more likely to occur than in others places along the DNA
The majority of mutation are neutral and have no effect on the health of the living organism
Mutations occur more than 1000 time per day in mammals
All the above statements are true about mutations. Mutation is a change in the structure of a gene due to either addition, deletion or rearrangement of segments and it will result in a variant form and it will transmitted to the subsequent generation.
We know most of the mutation occurring in the cell will be neutral and will not produce any harmful effect on our health, and hot spot regions will have 100 times more chances of getting mutated, it has been estimated that in mammalian cell there is a chance of occurrence of a mutation 10,000 times per day per cell.
When it comes to the statement “Organisms have ways of proofreading and repairing DNA”, it is the statement about the DNA repair, the statement is true, but cannot be included under mutation category.
