UGA BIOLOGY 1107 FINAL PAPER
4 QUESTIONS WITH VERIFIED
ANSWERS
⩥ Chromatin. Answer: -DNA and protein complex found in eukaryotic
cells
-prokaryotes do not contain chromatin
-DNA is packaged into nucleosomes that have histone protein cores
⩥ Which of the following molecules are found in the chromatin of
eukaryotic cells?. Answer: protein, nucleic acids, and monosaccharides
⩥ Chromosome. Answer: -a single piece of chromatin
-a replicated set of chromatin pieces that remain attached at the
centromere
⩥ Does the number of chromosomes matter?. Answer: yes, such as
replication
⩥ Chromatids. Answer: two identical chromosomes that split and
contain the same genetic material
,⩥ Human somatic cells usually have 23 chromosomes in their nuclei.
How many sister chromatids will such a cell have after DNA replication
but before cell division?. Answer: 92
⩥ Cell Cycle. Answer: -the event sequence during which a eukaryotic
cell replicates DNA and divides
-lengths of gap phases vary by the type of cell
-interphase: G1, S, and G2
⩥ Mitosis. Answer: -division of the nucleus that results in 2 identical
daughter nuclei
-interphases (including DNA replication) and cytokinesis are not apart of
mitosis
⩥ Cytokinesis. Answer: -division of the cytoplasm that results in 2
daughter cells
-not apart of mitosis
⩥ If a fruit fly zygote goes through mitosis four times but never
undergoes cytokinesis, what do you predict will be the outcome?.
Answer: one cell that has 16 identical nuclei
⩥ Can a cell have more than one nucleus?. Answer: yes
, ⩥ Phases of mitosis. Answer: prophase, prometaphase, metaphase,
anaphase, telophase
⩥ Prophase. Answer: -chromatin is going from decondensed to
condensed structure
-spindle is being constructed
⩥ Prometaphase. Answer: -the nucleus is decomposing
-allows spindle to attach to centeromer of chromosome
⩥ Metaphase. Answer: Chromosomes move to middle of the cell and
line up
⩥ Anaphase. Answer: -chromatids are pulled to opposite ends by the
spindles
-2 sets of chromatids
⩥ Telephase. Answer: -mew nuclear envelopes are developing around 2
sets of chromatids
-spindle decomposes
⩥ Cytokensis during mitosis. Answer: -starts during the end of anaphase
and ends after mitosis is complete
