BIO 340 Exam 1 Questions And Answers
100% Pass


Mitosis - answer✔-Creates two daughter cells IDENTICAL to parent.



-Happens in Somatic cells



-Parent cells is diploid (2n). So if there are 3 pairs of chromosomes 2n=6.

Human karyotpye is 2n=46

What is function of mitosis and meiosis? - answer✔They ensure the genetic continuity of nucleated cells

What are the phases of the cell cycle? - answer✔G1: growth and metabolism



S: DNA synthesis and chromosome duplication



G2: preparation for mitosis



M: Divison

Steps of Mitosis - answer✔IPMAT

1. Interphase

2. Prophase

3. Metaphase

4. Anaphase

5. Telophase

6. Cytokinesis

Interphase (Mitosis) - answer✔Chromosomes duplicate to produce sister

chromatids.

Prophase (Mitosis) - answer✔-Chromosomes become paired chromatids and are

visible.

-The nuclear envelope also disappears.

-Duplicated chromosomes condense

Metaphase (Mitosis) - answer✔Chromosomes line up in the middle of the cell

and attach to spindle fibers.

Anaphase (Mitosis) - answer✔Chromosomes are pulled apart from each other

and towards the poles of the spindle

Telophase (Mitosis) - answer✔-the chromosomes have reached the opposite

ends of the cell and the nuclear envelope starts developing and separating

the chromosomes into two new cells

-Chromosomes de-condense

Cytokinesis (Mitosis) - answer✔the final stage where the two cells actually

separate.

What is present before replication (Mitosis)? - answer✔-1 chromosome

-1 chromatid

-1 piece of DNA

What is present after replication (Mitosis)? - answer✔-1 chromosome

-2 chromatids

-2 pieces of DNA

What are sister chromatids? - answer✔Identical copies

At which points in the cell cycle will you likely not see chromosomes but

uncondensed DNA?

i. During Gap 1

ii. During Synthesis

iii. During gap 2

iv. All of the above - answer✔iv. All of the above

Where are genes located? - answer✔-On chromosomes

-Each chromosome has a distinct set of genes in specific locations

What is the number of chromatids in an organism with 4 chromosomes in G1 and G2? - answer✔-G1: 4
chromatids

-G2: 8 chromatids

What are characteristics of eukaryotic chromosomes? - answer✔-DNA carries the genes



-The molecule is linear



-Most of the time it is present in the cell in its uncoiled form associated with

proteins and RNA (chromatin)



-Its fragile and diffuse, which is a problem for cell division

--The solution for this is to package by multiple condensation

How many centrioles do centrosomes in animal cells have? - answer✔2

Microtubules - answer✔-form around the centrosomes

-build the spindle

apparatus

-some attach to the kinetochores which are on the

centromeres of chromosomes during cell division.

-They help pull

the chromosomes apart during anaphase

Chromatin - answer✔-the DNA that makes up a chromosome

-Chromosomes are the pieces of DNA made up of chromatin

Chromatids - answer✔the identical pieces of DNA held together by
