Teas 7 Prep Latest Exam Update
With All Correct Answers
Centrosome - ✔✔✔ANSWER-Assists in moving chromosomes throughout
the entire process. NOT the same as Centromere. Remember it like this,
chromosome ends with "some", so centro"some" refers to chromosome. They
have the same ending.
The cell cycle is divided into - ✔✔✔ANSWER-TWO major phases (Interphase
and mitosis)
At the beginning of S phase the cell has - ✔✔✔ANSWER-46 total chromatin
(23 maternal, 23 paternal)
Maternal - ✔✔✔ANSWER-From the mother
Paternal - ✔✔✔ANSWER-From the father
Interphase has _____ phases - ✔✔✔ANSWER-3
,G2 phase - ✔✔✔ANSWER-Cell continues to grow, centrioles begin to
elongate
G1 phase - ✔✔✔ANSWER-Cell is performing its normal task, begins to
replicate organelles
S phase - ✔✔✔ANSWER-DNA replication begins, after replication the cell
has 2x the amount of chromatin
Prophase - ✔✔✔ANSWER-First phase of mitosis.
- Chromatin becomes chromatids
- nuclear envelope begins to dissolve
- Centrosomes migrate to ends of cell
Cells spend 3/4 of their time in - ✔✔✔ANSWER-interphase
Metaphase - ✔✔✔ANSWER-- Kinetochores form at the centromere, holds
onto the microtubule and locks it in place.
- Microtubule spindles connect to centromere
- Chromosomes line up in the middle along the metaphase plate
- Nuclear envelope has completely dissolved
, Anaphase - ✔✔✔ANSWER-- Cell begins to elongate
- Sister chromatids are pulled apart from each other, leaving 46 on both sides
Telophase - ✔✔✔ANSWER-- Cleavage furrow pinches parent cells into two
identical daughter cells in a process called cytokinesis.
- Nuclear envelope is reformed
- Microtubules release chromosomes
G0 phase - ✔✔✔ANSWER-Cell resting phase
Mitosis produces - ✔✔✔ANSWER-2 diploid cells
Quiescent state - ✔✔✔ANSWER-Cells are dormant until stimulated. For
example liver cells only divide when there is some kind of viral stress, toxic stress,
or trauma to the organ occurs.
Senescent state - ✔✔✔ANSWER-Cells permanently do not enter the cell
cycle. For example a cell that is old or has permanently damaged dna.
Apoptosis - ✔✔✔ANSWER-Cells that are programmed to die after they
complete their task. For example, cells that line the digestive tract die every 2 to 3
days after completing their task
