ANSWERS (VERIFIED ANSWERS) |ALREADY GRADED A+
Why is only one strand of DNA transcribed into mRNA? - ans -Because the other
strand would produce the same amino acid sequence in reverse order
During which phase does crossing-over occur? - ans -prophase-I
What is the function of nucleosomes? - ans -To prevent DNA strands from
tangling.
Which of the following combinations of letters accurately represents two sister
chromatids? - ans -A and C
During which of the following stages of meiosis do the sister chromatids
separate? - ans -anaphase II
Which of the following combinations of letters accurately represents two
homologous chromatids? - ans -A and D
A maternal homologue and a paternal homologue synapse to form: - ans -a
tetrad.
Once nerve cells become mature, they don't usually undergo cell division. Based
on your knowledge of the cell cycle, you would predict that mature nerve cells
become arrested in the __________ of the cell cycle. - ans -G0 phase
The M phase of the cell cycle involves two main processes: - ans -mitosis and
cytokinesis.
The mitotic spindle is made of: - ans -microtubules.
A cell is in metaphase if: - ans -the chromosomes are aligned at the midplane of
the cell.
, During prophase, __________ is(are) compacted into visible chromosomes. - ans -
chromatin
__________ contain identical DNA sequences and are held together by
__________ during mitosis. - ans -Sister chromatids; centromeres
Duplicated centrioles start moving to opposite poles of a dividing __________ cell
during __________ of the cell cycle. - ans -animal; prophase
Cytokinesis in animal cells involves contraction of a ring of __________
microfilaments.
Answers:

If mitosis produced gametes in sexually reproducing organisms, then: - ans -
chromosome number would double in each generation
Which of the following events does not occur during meiosis I? - ans -separation
of sister chromatids
The correct number of chromosomes is maintained during sexual reproduction
