Biology 121 Final Exam questions and answers
Graded A+
hydrogen bonds - ✅✅Water molecules are attracted to one another by . . .
enzymes speed up chemical reactions, are required in minute amounts, are highly
specific in their action, are affected by temperature, are affected by pH, some
catalyze reversible reactions, some require co-enzymes, and they are inhibited by
inhibitors. - ✅✅Describe the characteristics of enzymes . . .
DNA is copied as mRNA, which is the template for protein synthesis. -
✅✅Describe the flow of genetic information . . .
hydrolysis creates monomers, and dehydration reactions break down polymers.
Dehydration reactions ionize water molecules and add hydroxyl groups to
polymers; hydrolysis reaction release hydroxyl groups from polymers.
Dehydration reactions assemble polymers, and hydrolysis reactions break down
polymers. - ✅✅Describe the relationship between dehydration reactions and
hydrolysis . . .
between prophase 1 and metaphase 1. - ✅✅Genetic recombination or
crossing-over occurs . . .
the arrangement of all chromosomes at the equator, or metaphase plate, of the
cell with polar microtubule fibers from opposite poles attached to the centromere
of each chromatid. - ✅✅Metaphase is characterized by . . .
, formation of random combinations of chromosomes in meiosis and on genes of
different pairs of homologous chromosomes by the passage according to the laws
of probability of one of each diploid pair of homologous chromosomes into each
gamete independently of each other pair. - ✅✅Define independent assortment
...
A measured amount of energy is released. - ✅✅What happens when ATP loses
a phosphate to form ADP?
normal growth and cell function - ✅✅The first gap in the cell cycle (G1)
corresponds to . . .
Half would be homozygous and half would be heterozygous. - ✅✅Reindeer's
noses lighting up like a bright red light bulb is a recessive trait. If you crossed a
homozygous male with a red light-up nose and a heterozygous female, what
would be the genotypes of the progeny?
one glucose molecule is split into two pyruvate molecules, using 2 ATP while
producing 4 ATP and 2 NADH molecules. - ✅✅Describe what happens during
glycolysis . . .
prophase, metaphase, anaphase, and telophase, followed by cytokinesis. -
