ANSWER ALL QUESTIONS IN THIS SECTION
QUESTION 1
What is binary fission? - ANSWERS-A form of asexual reproduction in which the
parent divides into two identical halves.
QUESTION 2
What is cytokinesis? - ANSWERS-The division of cytoplasm into two identical
daughter cells, which occurs during the telophase stage of mitosis.
QUESTION 3
What is a haploid cell? - ANSWERS-A cell that contains one set of chromosomes

QUESTION 5
What is chromatin? - ANSWERS-The substance of which eukaryotic
chromosomes are composed, consisting of mostly proteins, DNA, and RNA.
QUESTION 6
What is a centriole? - ANSWERS-a cylindrical organelle near the nucleus in
animal cells, occurring in pairs and involved in the development of spindle fibers
in cell division.
QUESTION 7
What is a chromosome? - ANSWERS-A structure carrying genes is a linear
sequence, found in the nucleus, consisting of DNA and protein.
QUESTION 8
What is DNA? - ANSWERS-A double-stranded, helical nucleic acid molecule
capable of replicating and determining the inherited structure of a cell's proteins. It
makes up the genetic material of most living organisms and plays a role in
determining heredity.

QUESTION 9
What is RNA? - ANSWERS-A single-stranded nucleic acid molecule involved in
protein synthesis. It is responsible for carrying the genetic code transcribed for
DNA to specialized sites within the cell where the information is translated into
protein composition.
QUESTION 10
What is a nucleotide? - ANSWERS-A nucleotide is the basic building block of
nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A
nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in
DNA) attached to a phosphate group and a nitrogen-containing base.
QUESTION 11
What is transcription? - ANSWERS-Transcription is the process by which the
information in a strand of DNA is copied into a new molecule of messenger RNA
(mRNA). ... This complex initiates transcription, and the RNA polymerase begins
mRNA synthesis by matching complementary bases to the original DNA strand.
