ANSWERS 2026/2027 | COMPLETE EXAM REVIEW
(1) Which statement is characteristic of the bacteria and makes them different from both the
archaea and the eukaryotes? - ✔✔Bacteria have no histones associated with their
chromosomes and the other two groups do.
In which stage of the cell cycle does the cell duplicate its DNA? - ✔✔S
Eukaryotic cells that contain more than two sets of genetic information are referred to as -
✔✔polyploid
What is the function of the telomere? - ✔✔to protect the end of a DNA molecule
What is the constricted region of the chromosome where the kinetochore forms? -
✔✔centromere
The products of mitosis normally - ✔✔are genetically identical to the parent cell.
Which stage of mitosis involves sister chromatids separating and moving toward opposite
poles? - ✔✔anaphase
In order to pass the G2/M checkpoint the cell must - ✔✔have its DNA completely replicated
and undamaged.
Assume that a cell has six chromosomes while it is in the G1 stage of the cell cycle.
, How many chromosomes and how many DNA molecules will it have in the G2 stage? - ✔✔6
chromosomes and 12 DNA molecules
In which stage of meiosis does the separation of homologous chromosomes occur? -
✔✔Anaphase 1
Meiosis results in genetic variation among its product cells.
One source of this genetic variation is the random distribution of maternal and paternal
chromosomes, and the other source of genetic variation is - ✔✔crossing over occurring at
prophase I.
Which of the statements is not a difference between mitosis and meiosis? - ✔✔Sister
chromatids separate during mitosis but not during meiosis.
Which molecule holds sister chromatids together during mitosis and meiosis? - ✔✔cohesin
Unique to prokaryotic cells - ✔✔- relatively small, typically less than 10 um in size
-Lack a true cytoskeleton
Both Cell Types - ✔✔-contain DNA
-use ribosomes to synthesize proteins
Unique to eukaryotic cells - ✔✔-nuclear membrane surrounds DNA
A cell has a circular chromosome and histone proteins associated with its DNA, but lacks a
nuclear membrane.
