1. Which of the following is the best description of a genome?
a. All of the genes of an organism
b. A sequence of DNA bases that code for a particular protein
c. A single molecule of DNA
d. A duplicated chromosome formed by DNA replication
2. The end result of mitosis is
a. two cells, each with half the number of chromosomes as the mother cell.
b. two cells, each with twice the number of chromosomes as the mother cell.
c. two cells identical in genetic material, but one is smaller than the other.
d. two cells identical in size and genetic material.
3. In an adult human, where would you find active mitosis occurring?
a. Bone marrow
b. Brain
c. Muscles
d. Testes and ovaries
4. In an adult human, where would you find active meiosis occurring?
a. Muscles
b. Brain
c. Bone marrow
d. Testes and ovaries
5. If meiosis occurs in a cell with a diploid number of chromosomes of 16 how many chromosomes will be in each daughter cell?
a. 4
b. 16
c. 8
d. 2
1. Option a is the right answer as the genome is defined as total genetic material present in a cell or organism or total genes present in the cells or organism.
2. Option d is the right answer as at the mitosis one somatic cells divided into two cells with equal size and genetic material.
3. Option a is the right answer because bone marrow is highly proliferative tissue which generates the blood cells by the process of mitosis.
4. Option d is the right answer because of testis or ovary are the place where gametes are formed by the process of meiosis.
5. Option c is the right answer as at the end of the meiosis daughter cells contained half of the mother cell chromosomes.
