Bio 123 Lab Exam 2 Questions
and Answers 100% Pass
Karyokinesis - CORRECT ANSWER:-division of the nucleus
Cytokinesis - CORRECT ANSWER:-division of the cytoplasm
Mitosis - CORRECT ANSWER:-production of two daughter nuclei that are
genetically identical to each other and the parent nucleus
Meiosis - CORRECT ANSWER:-reduces the chromosome number in daughter
nuclei to half that of the parent cell
Two types of nuclear division - CORRECT ANSWER:-mitosis and meiosis
What are produced in meiotic division? - CORRECT ANSWER:-gametes
Three phases of interphase - CORRECT ANSWER:-G1, S, G2
G1 phase - CORRECT ANSWER:-fist part of interphase where the cell is growing
S phase - CORRECT ANSWER:-second part of interphase where DNA synthesis
& reproduction occur
G2 phase - CORRECT ANSWER:-third part of interphase where the cell is
growing again
, M phase - CORRECT ANSWER:-mitosis and cytokinesis
Chromatin - CORRECT ANSWER:-granular material in the nucleus that is not
visible because it is uncoiled in this form
restriction point - CORRECT ANSWER:-occurs late in G1 and it determines if
the cell will continue to divide or not
G0 phase - CORRECT ANSWER:-nondividing cell that does not make it past the
restriction point on to the s phase
Nondiving cells examples - CORRECT ANSWER:-body cells like nerve and
muscle cells
Volume of cytoplasm/genome size - CORRECT ANSWER:-how the size is
measured to see if it is big enough to divide or not
Protein kinase - CORRECT ANSWER:-enzymes that control cell cycle activity by
phosphorylating specific proteins
Cyclins - CORRECT ANSWER:-proteins that regulate protein kinases and the cell
cycle
Cdk proteins (cyclin-dependent kinases) - CORRECT ANSWER:-specific complex
of enzymes that have to be present for the cell to pass the restriction point
Replication - CORRECT ANSWER:-two strands of the DNA helix unwind and
separate and each duplicate
