A gene is a short section of DNA. Your genes contain instructions that tell your cells to make molecules called proteins. Proteins perform various functions in your body to keep you healthy. Each gene carries instructions that determine your features, such as eye colour, hair colour and height.
Answer:
Somatic cells helps in healing and repairing damaged cells
Explanation:
Somatic cell division plays an important role in division of body cells. They help in healing and repairing the damaged cells. cell division is of two types, Mitosis and meiosis. Mitosis replicates and results in two identical daughter nuclei (genetically identical). Apart from these, they also act as adult stem cells which plays a major role in healing the damaged cells or repair the damaged cells. somatic cells are found all over your body except the germ cells.
Benefits of cell division in somatic cells:
- If you get hurt and eventually your blood will stop oozing out and get healed by the mitotic cell division found in the somatic regions of your body.
- Animals like lizards when get hurt, they get their cells automatically repaired by their somatic cells.
These are few important benefits other than the identical copies that are obtained by cell division.
Because most living things are made of or contain carbon. Living organisms need carbon to live, grow and reproduce.
Basically, all living organisms contain carbon and need it to survive and reproduce.
Answer:
- 100% of the girls are expected to be normal, X+X+ and X+X-
- 50% of the boys are expected to be normal, X+Y
- 50% of the boys are expected to be hemophilic, X-Y
- 75% of the whole offspring normal (X+X+, X+X-, X+Y)
- 25% of the whole offspring hemophilic (X-Y)
