Science Chapter 8 Quiz
Meiosis is a process used for
production of gametes.
The phase of mitosis in which the centromeres split and sister chromatids are pulled to opposite poles of the cell is
which is anaphase.
The phase of mitosis in which the chromosomes are aligned along the equator of the cell is
which is metaphase.
The phase of mitosis in which the nuclear envelope breaks into small pieces is
which is prometaphase.
The phase of mitosis in which the chromosomes condense and centrosomes move to opposite poles of the cell is
which is prophase.
The phase of mitosis in which the nuclear envelope reforms is
which is telophase.
An embryo fish is in its egg, without fully developed tissues and organs to survive outside the egg. The embryo has a large number of cells undergoing mitosis for the purpose of
production of new cells that can differentiate and specialize for different functions.
Apoptosis is a name for the process of
programmed cell death.
The correct sequence for the phases of mitosis, shown in correct sequence in this diagram, is
prophase - prometaphase - metaphase - anaphase - telophase.
A person, who has just experienced a painful sunburn, has a large number of cells undergoing mitosis for the purpose of
repairing and replacing the damaged cells, in the healing process of the skin.
Strong evidence of semiconservative replication of DNA comes from the DNA molecule structure, in that
the DNA molecule is double-stranded, allowing one original strand to be conserved while its replicate forms one strand.
How does the space between our fingers arise?
The cells die by apoptosis.
In which of these mitosis phases is the replication of DNA accomplished?
None of these answer options are correct, because replication does not happen during mitosis.
Why does a replication fork have a leading and lagging strand?
Both answers, with DNA synthesis proceeding from 5' to 3', and DNA polymerase only acting on the 3' end, are correct.
The molecule that contains the information for making a cell's proteins and copies itself for the next generation of cells is
DNA.
A nucleosome consists of
a stretch of DNA and histones.
The four nitrogen bases that are found in the different nucleotides of DNA are
adenine, thymine, cytosine, guanine.
While in the biology lab, you observe, in both plant and animal cells, that some single cells are splitting into two daughter cells, in the process of
cytokinesis.
A seedling plant has a section of the stem tip that contains large numbers of cells undergoing mitosis for the purpose of
growth in height of the plant.
Complementary DNA strands are held together by
hydrogen bonds.
The correct sequence for the phases of the cell cycle, starting with a newly divided cell, is
interphase - mitosis - cytokinesis.
The enzyme that builds a short complementary piece of RNA at the start of each DNA segment to be replicated is
primase.
