What are telomeres? - ✔✔✔ Correct Answer > ends of chromosomes
designed to protect from DNA shortening. Made of of 100s-1000s
of TTAGGG tandem repeats. Get increasingly short with each
division especially in somatic cells
Zygote - ✔✔✔ Correct Answer > a diploid cell resulting from the fusion
of two haploid gametes; a fertilized ovum.
Telomere shortening does not occur in which types of cell? - ✔✔✔
Correct Answer > gametes and stem cells. They contain telomerase, a
reverse transcriptase that binds to the ends of the tails and adds
repeats. Potentially useful for aging/cancer
Karyotype - ✔✔✔ Correct Answer > A display of the chromosome pairs
of a cell arranged by size and shape.
,Page 2 of 30
Ploidy - ✔✔✔ Correct Answer > number of sets of chromosomes in a
cell
Haploid vs diploid - ✔✔✔ Correct Answer > one set of chromosomes vs
two sets of chromosomes
Mitotic spindle - ✔✔✔ Correct Answer > a structure made of
microtubules that controls chromosome movement during
mitosis
Unlike animals, during cell division, plant cells do not contain
____ - ✔✔✔ Correct Answer > centrosomes (though they do have
mitotic spindle). Final location defines the poles.
Phragmoplast - ✔✔✔ Correct Answer > In dividing plant cells, a
structure formed by overlapping microtubules that guide vesicles
containing cell wall components to the middle of the cell.
Meiosis occurs in _______ - ✔✔✔ Correct Answer > most eukaryotes
Binary Fission steps - ✔✔✔ Correct Answer > -Initiated when proteins
attach DNA to plasma membrane
-Begins along ORI region
-Newly synthesized DNA also anchored to membrane
, Page 3 of 30
-Cell elongates until ~2 times its original size and two has two
chromosomes on opposite ends of the cell
-Cell splits in two
Quiescent stem cells, function - ✔✔✔ Correct Answer > Permanently
arrested in G0 phase. In adults: can replace non-reproducing
specialized cells) ex adult skeletal muscle/myofiber)
Steps of quiescent stem cell to myofiber - ✔✔✔ Correct Answer > -
Activated (reenter cell cycle)
-Proliferative (look over this one)
-Commitment to differentiation
-Fusion into myotube (precursor of myofiber)
-Myofiber
Steps of cell cycle - ✔✔✔ Correct Answer > G1 phase
S phase
G2 phase
M phase
~G0 phase~ perhaps
G1 phase - ✔✔✔ Correct Answer > growth phase, prepares cell for dna
synthesis
