MUTATIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A mutation occurs to a gene in a body cell that results in tumors growing along a person’s nerves or under the skin. They increase the chances of the person having learning disabilities. The impact of this mutation on the organism is ____
A
beneficial.
B
harmful.
C
neutral.
Explanation: 

Detailed explanation-1: -A mutation occurs to a gene in a body cell that results in tumors growing along a person’s nerves or under the skin. They increase the chances of the person having learning disabilities. Analyze the impact of this mutation on the organism. The mutation is beneficial.

Detailed explanation-2: -Answer to: When a mutation occurs in a gene involved with cell growth or division, resulting in the uncontrolled growth of cells, this condition is called cancer.

Detailed explanation-3: -A genetic mutation is a change to a gene’s DNA sequence to produce something different. It creates a permanent change to that gene’s DNA sequence. Genetic variations are important for humans to evolve, which is the process of change over generations. A sporadic genetic mutation occurs in one person.

Detailed explanation-4: -If a mutation occurs in a germ-line cell (one that will give rise to gametes, i.e., egg or sperm cells), then this mutation can be passed to an organism’s offspring. This means that every cell in the developing embryo will carry the mutation.

Detailed explanation-5: -Mutations in somatic cells are called somatic mutations. Because they do not occur in cells that give rise to gametes, the mutation is not passed along to the next generation by sexual means.
