Mitosis involves the
replication of DNA within the cell
the creation of a zygote
the division of one cell into two identical cells
the division of one cell into two unique cells
The picture depicts which process?
Mieosis
Mitosis
DNA replication
Fertilization
Bacteria reproduce by going through the process of
mitosis
meiosis
interphase
binary fission
After meiosis, we end up with
two gametes, each of which has the same number of chromosomes as the parent cell
two gametes, each of which has half the number of chromosomes as the parent cell
four gametes, each of which has the same number of chromosomes as the parent cell
four gametes, each of which has half the number of chromosomes as the parent cell
Gamete is the fancy word for
Sperm
Egg
Reproductive cells
Body cells
A zygote is a
skin cell
bone cell
fertilized egg
sperm cell
If a rat has 92 chromosomes (2n), how man chromosomes would each daughter cell have after undergoing meiosis?
92
46
184
How many chromosomes are in a human sex cell?
46
23
42
21
DNA replicates during which phase of the cell cycle
G1
S
G2
M
What is happening during interphase?
Cell develops a second nucleus
The cell is preparing for division
The cell shrinks and breaks apart
The cell divides into two new cells
During which stage of mitosis do the chromosomes align in the middle of the cell
Telophase
Anaphase
Metaphase
Prophase
During which stage of mitosis do the chromosomes move to opposite poles of the cell
Telophase
Anaphase
Metaphase
Prophase
Which is an advantage of sexual reproduction when compared to asexual reproduction?
Finding a partner
Takes more time
Genetic variation
During the cell cycle, DNA is replicated. This step takes place
after mitosis
during interphase
during mitosis
between interphase and mitosis
Binary fission, budding and fragmentation are all examples of (select all that apply)
asexual reproduction
sexual reproduction
mitotic process
meiotic process
This process results in more diverse offspring due to a combination of genetic material from the male and female parent
genetic recombination
binary fision
asexual reproduction
sexual reproduction
Which of the following pairs the type of reproduction and the cell process involved?
sexual reproduction: mitosis and binary fission
sexual reproduction: meiosis
asexual reproduction: mitosis and meiosis
asexual reproduction: meiosis
The cell cycle includes the following stages: G1, S, G2, mitosis and cytokinesis. When is DNA replicated?
G1
S
Miosis
Cytokinesis
Meiosis produces what kind of cells?
Skin cells
Stigmates
Gametes
Homologous osteocytes
UV Rays can cause mutations in the DNA of skin cells. Will this mutation have effect on future generations?
Yes, because skin cells play a role in reproduction
Yes, because DNA is passed from parent to offspring
No, because the changes have no effect on the gametes of the parents
No, because offspring are immune to changes in parental DNA
Will multiple insertion mutations affect genetic variability? Why or why not?
No, because inserted nucleotides are not translated along the original DNA sequence
Yes, because lengthening the DNA sequence will keep genetic information stable during meiosis
Yes, because changing the DNA sequence will alter the amino acid sequence that codes for traits
No, because adding more nucleotides in a DNA sequence does not alter the coding of proteins
Which of the following shows the correct sequence of the cell cycle?
G1 → S → G2 → mitosis
mitosis → G1 → G2 → S
G1 → G2 → S → mitosis
S → G1 → G2 → mitosis
Which of the following describes how both of these processes maintain genetic continuity?
Both processes create cells with twice the genetic material of the parent cell
Both processes involve the
replication and division of
identical genetic material.
Both processes creates cells with 1/2 the genetic material.
What led to to the development of herbicide-resistant weeds?
Spontaneous reproduction
Artificial selection
Genetic cloning
Genetic engineering
Who done it?!
Suspect 1
Suspect 2
Suspect 3
Which claim about crossing over in chromosomes is true?
Crossing over increases genetic diversity by creating new combos of genes.
Crossing over decreases genetic diversity by adding new nucleotides.
Crossing over increases genetic diversity through deletion.
Crossing over decreases genetic diversity through mutation.
