Which of the following is NOT a primary function of mitosis?
Generate genetic diversity
Which of the following is NOT a primary function of meiosis?
Growth
Using the figure below from your booklet and your understanding of mitosis
and meiosis, select the biological process that occurs at each point during
the human life cycle.
Meiosis - chromosome number is halved to produce haploid gametes
Fertilization > egg and sperm fuse to produce a diploid zygote
Mitosis > cells with the same set of DNA divide and develop into an
organism
Mitosis AND Meiosis > multicellular adults use mitosis for repair and
growth; adults produce sperm and egg via meiosis
Based on what you've learned in class, why is generating genetic diversity
important from an evolutionary perspective?
Meiosis generates genetic diversity in eggs and sperm. This diversity
results in offspring containing slight differences in DNA from their parents,
allowing for genetic diversity between generations.
One way this diversity is important for survival and reproduction of
individuals in populations is that organisms have a better chance of
surviving in a changing environment.
Some women use ovulation kits to determine when they are ovulating.
Ovulation kits work by detecting the amount of luteinizing hormone (LH) in
a woman's urine.
A woman took an ovulation test and the levels of LH were high in her urine.
Based on what you know about the female reproductive cycle from class
and your booklet, why do you think ovulation kits are designed to detect
, follicle-stimulating hormone. The peak of LH triggers the release of the egg
from the follicle about 1-2 days following the surge.
High levels of LH signify that ovulation is about to occur, so this woman will
ovulate in the next day or two.
Which of these investigations could NOT be addressed using gel
electophoresis?
WRONG ANSWER - Checking for genomic DNA contamination and purity
of samples
Use the figure below to determine which biological concepts are
represented by the punnet square tool used in class.
1. Meiosis
2. Independent Assortment
3. Fertilization
4. Genotype
5. Phenotype
Which of the following is TRUE regarding the types of macromolecules?
(see table 7-1 in your lab manual)
Nucleic acids store, transmit, and help express genetic information.
Cells produce energy using glucose in a process known as cellular
respiration (See figure above). Which of the following BEST describes how
this process is related to macromolecules?
Glucose is an essential carbohydrate for life. Carbohydrates are critical for
biological functioning because they provide energy (ATP) to cells as well as
storage and support to cellular structure.
Which of the following BEST describes the flow of information in the central
dogma in biology?
DNA > RNA > Protein
