BIOD 210 Portage BIOD Module 4 Latest Update 2024-2025 Actual Exam Questions and 100% Verified Correct Answers Guaranteed A+
5' (five prime) end and 3' (three prime end) of DNA - CORRECT ANSWER: 5: phosphate group
3: hydroxyl group
Anaphase - CORRECT ANSWER: 1. Separation of the sister chromatids 2. Movement
of the separated chromatids toward the centrosome pole 3. Elongation of the cell
Arrangement of DNA - CORRECT ANSWER: antiparallel arrangement, the strands are
oriented with one strand being in the 5'→3' orientation and the other strand in the 3'→5' orientation
Autosome - CORRECT ANSWER: Any chromosome that is not a sex chromosome ( 22
autosome and 1 sex chromosome)
Cell cycle definition - CORRECT ANSWER: The process of a parent cell replicating its genetic information and physically dividing into two new daughter cells
Centrosome - CORRECT ANSWER: Organizes microtubules; participates in spindle
formation during cell division. Is composed of several filament and microtubules fibers with a pair of centrioles.
Chromatin - CORRECT ANSWER: Sequences and proteins that are in the nucelus of
the cell
Codominance - CORRECT ANSWER: A condition in which both alleles for a gene are
fully expressed
- / 2
Cohesions - CORRECT ANSWER: Specialized proteins that hold together the
chromatids
Complete dominance - CORRECT ANSWER: The phenotype for a dominant trait is
exhibited regardless of genotype EX PP and Pp both result in purple phenotype
Egg cell and sperm cell chromosomes - CORRECT ANSWER: Egg: X Sperm X or Y
XX= females XY= male
Example of internal signaling regulation - CORRECT ANSWER: M checkpoint because
the protein complexes needed to activate telophase will only occur when the spindles are properly attached
G0 phase - CORRECT ANSWER: A nondividing state occupied by cells that have left
the cell cycle
G1 checkpoint - CORRECT ANSWER: Checks the surroundings to make sure the
conditions are favorable and the cell is healthy enough to enter the next stage. once the cell proceeds through this checkpoint, it has committed to division.
G1 phase, S phase, G2 phase events - CORRECT ANSWER: Gap phase 1: Growth phase. Messenger RNA and proteins needed for DNA synthesis are produced during this phase
S phase: DNA synthesis. DNA is duplicated
Gap phase 2: Cell growth + cell synthesis of proteins and organelles needed for mitosis
G2 checkpoint - CORRECT ANSWER: asses if DNA replication has occurred, go ahead
signal triggers mitosis. this checkpoint focuses on ensuring the quality and completion of DNA replication
