Cell Reproduction

True/False Indicate whether the sentence or statement is true or false.
	1.	The information needed by a cell to direct its activities and to determine its characteristics is contained in molecules of deoxyribonucleic acid (DNA).
	2.	Gametes are diploid so that when fertilization occurs, the resulting zygote will have the characteristic number of chromosomes for that species.
	3.	A karyotype is a type of gene.
	4.	Cell division in bacteria and eukaryotes takes place in precisely the same manner.
	5.	Cells spend most of their lifetime in interphase.
	6.	After the replication of a cell’s chromatids, there are twice as many centromeres as there are chromosomes.
	7.	Asexual reproduction occurs by mitosis.
	8.	During telophase, a nuclear envelope surrounds each new set of chromosomes.
	9.	Chromatids separate from each other during telophase.
	10.	After mitosis and cytokinesis, each new cell has a complete set of the original cell’s chromosomes.
Completion Complete each sentence or statement.
