Question 1

description of what happens in each phase of mitosis

Question 2

Interphase

Answer 2

Cell cycle when the cell grows, copies it’s DNA, and prepares to divide.

Question 3

Prophase

Answer 3

DNA and proteins condense into tightly coiled chromosomes. The nuclear envelope breaks down, centrioles begin to move to opposite poles, and spindle fibers form

Question 4

Metaphase

Answer 4

spindle fibers attach to each chromosome. They align the chromosomes along the cell equator

Question 5

Anaphase

Answer 5

Chromatids separate to opposite sides of the cell. Cytokinesis usually begins in late anaphase or telophase

Question 6

Telophase

Answer 6

Nuclear membranes start to form, chromosomes begin to uncoil, and the spindle fibers fall apart

Question 7

description of what happens in each phase of the cell cycle

Answer 7

increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).

Question 8

what nucleotides contain

Answer 8

Sugar molecule
In DNA: deoxyribose
In RNA: ribose

Phosphate group

Nitrogen containing base
In DNA: ATCG
In RNA: AUCG

Question 9

the base pairing combinations for DNA and RNA

Answer 9

In DNA: ATCG
In RNA: AUCG
