Answer:
C. tumor suppressor
Explanation:
Tumor suppressor genes encode for proteins which inhibit cell proliferation in some way. One copy of this gene is sufficient to control cell proliferation so both the alleles must be mutated to promote tumor development. Mutation may be a deletion or point mutation.
Tumor suppressor genes are known to code for five classes of proteins:
- Intracellular proteins which inhibit cell proliferation through specific stage of cell cycle
- Receptors for hormones that inhibit cell proliferation
- Apoptosis promoting proteins
- Enzymes involved in DNA repair
- Check point control proteins that arrest cell cycle on detecting any abnormality
Answer:
gain; 56 loss; 24.
Explanation:
Lotka‒Volterra dynamic is a kind of dynamic which shows the interaction between two organisms i. e. one is predator and the other is prey. Populations of both organisms are dependent on each other. If one population is increased the other organism population will be reduced due to more feeding. Rabbit population grows double than it is reduced due to feeding by foxes. Decrease occurs in the population of foxes due to death which increases the population of rabbit in that ecosystem.
