What is the definition of the cell cycle? - correct answer ✔The life of a cell from the time it is first
formed from a dividing parent cell until its own division into two cells
What are the two independent components of cell division called? - correct answer ✔Mitosis and
Mieosis
What kind of organism uses cell division as a means of reproduction? - correct answer ✔Prokaryotics
What are the key roles cell division plays in biology? - correct answer ✔Reproduction; Growth and
Development; Tissue Repair and Renewal
What is a genome? - correct answer ✔all the DNA in a cell
How many chromosomes does a typical prokaryote possess? - correct answer ✔one
Where are the chromosomes are found in a eukaryotic cell? - correct answer ✔in the nucleous
Where is the extra-chromosomal DNA found in animal cells and in plant cells? - correct answer
✔Mitochondria
What are the two macromolecules that make up chromatin? - correct answer ✔DNA and Protiens
, Which component of chromatin that is responsible for DNA condensation? - correct answer ✔DNA
replication
Human somatic cells have 46 chromosomes. DO algae, hedgehog and elephants also have 46
chromosomes? - correct answer ✔No, they don't because each species has a specific number of
chromosomes that define who they are biological.
What is a human Somatic Cell and how many sets of chromosomes does it possess? - correct answer
✔A non-reproductive cell that has two sets of chromosomes; humans have two sets of 23 chromosomes
Where do maternal chromosomes come from? - correct answer ✔The mother(X and X)
Where do paternal chromosomes come from? - correct answer ✔The father(X and Y)
How many maternal and how many paternal chromosomes are found in each human somatic cell? -
correct answer ✔46
What is a human gamete cell and how many sets of chromosomes does it possess? - correct answer ✔a
reproductive cell that has 1 set of 23 chromosomes
Given a metaphase chromosome, identify the telomeres, arms and centromere. - correct answer ✔The
telomeres are the top and bottom of the chromosomes; the arms are spersted by the centromere which
is what holds the arms together
Why do metaphase chromosomes look like the letter X? - correct answer ✔There are sister chromatids
that are connected by cohesins on the centromere
Chromosomes observed during mitosis are duplicated chromosomes. What is each member of the
duplicated chromosome called? - correct answer ✔Sister chromatids
