BSC 1005 GENETICS AND
HEREDITY FSU
if a strand of DNA is 20% gaunine, what is the percentage of
thymine? - ANSWERS-30%
C goes with G
A goes with T
autosomal recessive - ANSWERS-skips a generation, shows up in
both sexes
x-linked dominance - ANSWERS-all males have it and shows up in
some females
x-linked recessive - ANSWERS-shows up on all males
sex-influenced - ANSWERS-vary in expression depending on the sex
of the individual, but these genes are not linked to the sex
chromosomes
S-phase (a part of interphase) - ANSWERS-the replication of DNA
G1 (a part of interphase) and G2 - ANSWERS-cell growth period
, prophase (mitosis) - ANSWERS-chromosomes condense in spindle
forms
metaphase(mitosis) - ANSWERS-chromosomes line up at the equator
anaphase(mitosis) - ANSWERS-chromosomes separate into two
genetically identical groups and move to opposite ends of the spindle
telophase (mitosis) - ANSWERS-cells begin to spread out
cytokinesis - ANSWERS-cell splits into two daughter cells. 23
chromosomes each and are diploid
difference between mitosis and meiosis (how many daughter cells/
how many times each phase happens) - ANSWERS-in meiosis there
are 4 daughter cells and each stage happens twice
aneuploidy - ANSWERS-refers to at least one or more or one less
chromosome than the diploid number (ex. klinfelter xxy or turner
syndrome xo)
watson and crick - ANSWERS-the people who came up with the
structure of DNA (double helix)
codon - ANSWERS-sequence of three nucleotides (in DNA)
