Meiosis
How many chromosomes are in an adult human?

What would you find in chromatin?
DNA and histones
In order for a cell to divide, all of its genetic information has to be duplicated through a process called DNA ____________
Replication
What are the functions of mitosis in a multicellular organism?
Replace cells that are lost each day to normal wear and tear, allow growth from a zygote into an adult, and repair damaged tissue after injury.
What is fertilization?
Process that results in the union of sperm and an egg….
DNA replication occurs in what phase?

Mitotic spindle is composed of protein fibers called……
Microtubules
Apoptosis……
Cell death that is a normal part of development.
What is also known as “programmed cell death”?
Apoptosis
In a plant cell, what separates the daughter cells, marking the site where a new cell wall will form???
Cell plate
When an animal cell undergoes cytokinesis, what is formed and a contractile ring pinches the two cells apart?

What is the enzyme that adds new DNA nucleotides complementary to the bases on the exposed strand?
DNA polymerase
What forms covalent bonds between adjacent DNA segments?
Ligases

Mutation
An asexual process that replicates DNA and distributes it into two daughter cells is…..
Binary Fission
