Genetic change in the reproductive cells of the body (ovule or sperm) that is incorporated into the DNA of each cell in the body of the descendants. Hereditary mutations are transmitted from parents to children. It is also called germline mutation.
Answer:
elongation rate of strain of S.cerevisiae during transcription.
wild-type and experimental strain not treated with soultion of amanitin will be the control group. The elongation rate of mRNA of this group must be observed.
Explanation:
Dependent variable is one whose value depends on another value. Here effect of presence of mRNA polymerase enzyme and inhibtor on elnogatino rate of mRNA is being observed. So elongation rate is the dependent variable
Control group is one where independent variable whose effect is being observed can't influence the results. In experiment 2, the effect of inhibitor is being observed. So the control group must not have that inhibitor. Other conditions must remain same for experimentan and control group.
Gametes are mature haploid cells, or sex cells. When gametes unite with others from the opposite sex in the form of fertilization they create a zygote which then forms an embryo etc. At the end of meiosis the gametes only have <u>half</u> the chromosomes of the organism (only one copy of DNA)
Answer: C. It allows gametes to have half the original number of chromosomes of the organism.
