BIOL133 K006 MITOSIS LAB COMPLETE STUDY
GUIDE WITH SOLVED QUESTIONS
◉ gene.
Answer: A segment of DNA on a chromosome that codes for a
specific trait
◉ genome.
Answer: All the genetic information in an organism; all of an
organism's chromosomes.
◉ histone.
Answer: any of a group of basic proteins found in chromatin.
◉ Nucleosome.
Answer: repeating subunit of chromatin fibers, consisting of DNA
coiled around histones
◉ Chromatin.
Answer: (uncondensed) Clusters of DNA, RNA, and proteins in the
nucleus of a cell
, ◉ Chromatid.
Answer: (condensed) one of two identical "sister" parts of a
duplicated chromosome
◉ cell cycle.
Answer: series of events that cells go through as they grow and
divide
◉ Interphase.
Answer: Cell grows, performs its normal functions, and prepares for
division; consists of G1, S, and G2 phases
◉ G1 phase.
Answer: The first gap, or growth phase, of the cell cycle, consisting of
the portion of interphase before DNA synthesis begins; longest
phase
◉ S Phase (interphase of mitosis).
Answer: Synthesis and replication of chromosomes
◉ G2 phase.
Answer: stage of interphase in which cell duplicates its cytosol and
organelles
