ANSWERS GRADED A+
⩥ chromosomes.
Answer: reproduction requires the transmission of what from parent to
offspring
⩥ chromosomes.
Answer: structures within living cells that contain the genetic material -
the genes
⩥ DNA (genetic material) and Proteins (to provide an organized
structure).
Answer: Chromosomes are composed of what two things?
⩥ chromatin.
Answer: In eukaryotes the DNA-protein complex is called?
⩥ euchromatin.
Answer: The less condensed form of eukaryotic chromatin that is
available for transcription.
,⩥ Heterochromatin.
Answer: Eukaryotic chromatin that remains highly compacted during
interphase and is not transcribed.
⩥ prokaryotes.
Answer: Single-celled organisms without a nucleus and membrane
bound organelles (includes bacteria and archaea)
⩥ eukaryotes.
Answer: organisms that are made up of one or more cells that have a
nucleus and membrane-bound organelles; includeds protists, fungi,
plants, and animals
⩥ nucleoid.
Answer: prokaryotes usually contain a single type of circular
chromosome called what?
⩥ Cytogenetics.
Answer: Involves the microscopic examination of chromosomes;
examines the chromosomal composition of a particular cell or organism
⩥ somatic cells.
Answer: body cells, other than gametes are what type of cells
,⩥ gametes (germ cells).
Answer: sperm and egg cells are...
⩥ karyotype.
Answer: an organized representation of chromosomes within a cell
⩥ True.
Answer: True or False: Each chromosome has a unique size, shape and
banding pattern (light and dark areas) on a karyotype?
⩥ diploid and haploid (respectively).
Answer: what is the term meaning "2 sets of chromosomes" and "1 set of
chromosomes"
⩥ homologs (two homologs form a homologous pair).
Answer: Members of a pair of chromosomes are called what?
⩥ -Are nearly identical in size
-Have the same banding pattern
-Have the same centromere location
-Have the same genes (but not necessarily the same alleles).
Answer: explain the characteristics of homologous pairs (4 things)
, ⩥ No; They differ in size and genetic composition, but do have short
regions of homology.
Answer: are sex chromosomes (X and Y) homologous?
⩥ homozygous.
Answer: both homologs carry the same allele of a gene
⩥ heterozygous.
Answer: homologs carry different alleles of a gene
⩥ locus.
Answer: physical location of a gene on a chromosome
⩥ identical daughter cells.
Answer: One purpose of cell division is asexual reproduction. Asexual
reproduction results in...
⩥ binary fission.
Answer: how do bacteria reproduce?
⩥ it does not involve genetic contributions from two different gametes.
