QUESTIONS WITH FULL SOLUTION GRADED
A+
◉ genome. Answer: a cell's genetic info
◉ chromosome. Answer: structure that holds all DNA
◉ sister chromatid. Answer: joined copies of original chromosomes
◉ chromatin. Answer: complex of macromolecules found in cells,
consisting of DNA, protein, and RNA.
◉ somatic cells. Answer: all body cells except the reproductive cells,
46 chromosomes
◉ gametes. Answer: reproductive cells, sperm and egg
◉ centromere. Answer: region of chromosomal DNA where
chromatid is attached most closely to sister chromatid
, ◉ mitotic (M) phase. Answer: division of genetic material in the
nucleus, includes mitosis and followed by cytokinesis, usually
shortest part of cell
◉ interphase. Answer: 90% of the cycle. it is divided into subphases-
longest phase of the cell cycle- contains G1,S, and G2 phases
◉ G1 phase. Answer: first gap- cell grows
◉ S phase. Answer: synthesis- copies DNA
◉ G2 phase. Answer: second gap- cell grows and has more
organelles
◉ prophase. Answer: first stage mitosis, in which the chromatin
condenses into discrete chromosomes visible with a light
microscope, the mitotic spindle begins to form, and the nucleoulus
disappear , centromsomes move away from each other.
◉ prometaphase. Answer: second stage of mitosis, in which the
nuclear envelope fragments and the spindle microtubules attach to
the kinetochores of the chromosomes
