Chapter 9, Problem 3MCQ
Summary Introduction
Introduction:
The chromosomes are formed by the packing of the DNA (deoxyribonucleic acid) onto the protein molecules. The packing of the DNA condenses its length and allows it to fit into the nucleus. Most of the sexually reproducing organisms are diploid that is they have two sets of chromosomes in a cell.

Students have asked these similar questions
How many chromatids are visible in a human cell at the start of anaphase I? a. 23 c. 92 b. 46 d. 184
What is the purpose of mitosis?
a
It ensures that new nuclei have an exact copy of DNA.
b
It ensures the reproduction of mitochondria and chloroplasts.
c
It guarantees that each daughter cell has half the amount of DNA of parent cells.
d
It prevents the occurrence of cancer cells.
Why is there a need to produce diploid type of cell at the of cell division?
a.)So that the cells produced are exact copy of the parent cell
b.)So that abnormalities of the cell will be avoided
c.)So that the purpose of growth happens in the organism
d.)So that the copy of DNA is retained
