Total questions: 20
Worksheet time: 10mins
What is the significance of crossing over during meiosis?
No impact on genetic variation
Causes mutations
Genetic recombination and increased genetic diversity
Decreased genetic diversity
Explain the events that occur during metaphase I of meiosis.
The nuclear envelope breaks down
The chromosomes replicate to form sister chromatids
Homologous chromosomes line up at the metaphase plate and are attached to the spindle fibers at their centromeres.
The cell divides into two daughter cells
What is the end result of meiosis?
One daughter cell with double the number of chromosomes
Two daughter cells with the same number of chromosomes
Eight daughter cells with the same number of chromosomes
Four daughter cells with half the number of chromosomes
95% of the cells life cycle
Stage where DNA is copied
Interphase
Metaphase
Telophase
Prophase
Nuclear membrane disappears
Chromosomes can now be seen
Centrioles move to opposite sides
Metaphase
Interphase
Telophase
Prophase
in the cell cycle, what is the next stage after TELOPHASE (most of the time)?
Metaphase
anaphase
cytokinesis
interphase
Put the following stages of the cell cycle in order: G2, S, G1, M.
S, G1, G2, M
G1, S, G2, M
G1, M, G2, S
M, G1, S, G2
True or False: Viruses are the smallest living cells.
True
False
True or False: Viruses contain DNA or RNA genetic material.
True
False
True or False: Viruses have their own cell membrane and cytoplasm.
True
False
Viruses can sometimes hide their DNA within a cell's DNA and reactivate later.
True
False
Viruses attach only to a particular host because of the presence of
DNA
magnetic attraction
surface receptors
other viruses
viruses are non-living because
they cannot reproduce on their own
they do not evolve
they have no DNA
they cannot be destroyed
The organism that a virus enters and uses to reproduce is called a
host
parasite
guest
