100
What does the complementary base pairing rule state in DNA?
A always binds to T
C always binds to G
100
What does RNA stand for?
Ribonucleic Acid
100
What happens at the end of mitosis when cytoplasm splits?
Cytokinesis
100
What is the purpose of Mitosis?
Mitosis produces 2 IDENTICAL daughter cells OR Growth and repair of cell tissue
100
True or False: The cell spends most of its life cycle in mitosis, not interphase.
False
200
What is the complimentary DNA strand for:
TACGGTACG
ATGCCATGC
200
What kind of sugar is present in an RNA molecule?
Ribose
200
In what part of the cell does DNA replication occur?
the nucleus
200
What phase occurs after anaphase?
Telophase
200
What occurs during S phase?
A cell replicates its nuclear DNA
300
What are each of these parts?
A: Deoxyribose Sugar
B: Phosphate
C: nitrogenous base
300
RNA is double or single-stranded?
Single stranded
300
What part of the cell cycle do cells spend most of their time?
Interphase!! (90%)
300
What happens after the chromosomes line up in the middle?
Spindle fibers separate chromosomes and pull them to either side of the cell
300
What occurs after G2?
Mitosis - Prophase
400
Describe the structure of a DNA molecule.
Double stranded and twisted. Double helix.
400
What is the function of messenger RNA?
Carry the genetic code in DNA inside the nucleus to ribosomes in the cytoplasm
400
During which phase of the cell cycle does DNA replication occur?
DNA in the cell is replicated during Interphase (S phase)
400
What happens after the chromosomes separate?
The cell pinches in the middle (cytokinesis) and 2 identical cells are produced
400
What occurs during G1?
The cell grows, duplicates organelles and creates proteins required for mitosis.
500
True/False?
DNA strands are parallel
FALSE - DNA strands are anti-parallel
500
What is the complementary RNA strand to the following DNA strand?
ATT GCC TGC AGT
UAA CGG ACG UCA
500
If a fly has 10 chromosomes in each of its body cells, how many chromosomes will be in each daughter cell after mitosis?
10
500
What structure(s) allow for chromosomes to separate and move during mitosis?
Centrioles and spindle fibers
500
What part of the cell cycle would cancer spend most of its time? (Interphase or Mitosis)
Mitosis - it's constantly dividing!
