B) a segment of a DNA molecule that contains the instructions for producing all the characteristics of an
organism
C) a segment of a DNA molecule found only in the gametes of an organism
D) a segment of a DNA molecule that contains the instructions for producing a trait in an organism
2 The processes of deletion, insertion, and substitution can alter genes in a skin cell. The altered genes will

D) a segment of a DNA molecule that contains the instructions for producing a trait in an organism

Explanation: A gene is a DNA segment which contains the information needed in producing a protein or an RNA molecule. The protein coded for by a gene is responsible for controlling a particular trait in an organism. Usually one gene codes for one protein and one protein controls one trait in an organism. A gene is a unit of hereditary.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.

answer: that would be cheating
