ANSWERS) /ALREADY GRADED A+
VERSION A
What is a point mutation (substitution)
a mutation affecting only one or very few nucleotides
in a gene sequence. Most likely to lead to a beneficial
new function compared to other mutations.
What is DNA Polymerase and what is its function?
DNA Polymerase is a protein which comes from DNA
and reads, copies, and proof reads DNA. If there is a
mutation in the DNA the DNA Polymerase would be
responsible for not correcting it during proof
reading.
What does three nucleotides make?
A codon which would be transcribed from DNA to
mRNA and then translate mRNA to an Amino Acid
which are combined with other Amino Acids to make
a protein.
,What is a Insertion mutation (gene)?
a mutation in which one or more pairs of nucleotides
are inserted into a gene. This results in all the
nucleotides after that being pushed down the line,
completely changing the sequence.
What is a deletion mutation?
a mutation in which one or more pairs of nucleotides
are removed from a gene. This results in the
nucleotide sequence being completely messed up.
Mutation rates evolve based on two variables?
Mutation rates evolve according to the benefit of
variation and the cost of tinkering with proteins.
True or False #20: In a rapidly changing
environment, a population would likely benefit from
more frequent mutation.
true
What is a dominant allele?
when one copy of an allele determines the
phenotype of the individual
What is a recessive allele?
when two copies of an allele determines the
phenotype of the individual
What is a Heterozygous (hybrid)?
,when an individual carries two different alleles for a
gene
What is homozygous?
when an individual carries two identical alleles for a
gene
What is a homologous chromosomes?
when two chromosomes contain the same genes
What is heritable
when the variation in a phenotype depends on genes
Diploid (2n)
when a cell contains two copies of each
chromosome
haploid cell
when a cell contains one copy of each chromosome
why is the polarity of amino acids important when
dealing with mutations?
because a mutation changing an amino acid from
polar to non-polar or vise-versa can omit the
protein's function. this makes the mutation not
beneficial
Is there a redundancy in base pairs of condones and
amino acids?
yes, in the third base especially
, what is a silent mutation?
A Silent Mutation is a change in a nucleotide of a
codon, but no change in the Amino Acid coded for
which doesn't hurt or benefit the protein.
True or False #21: A point mutation in the third
position of a codon is more likely to change the
structure of the protein synthesized from the gene.
false
Why did the genetic code evolve?
The genetic code evolved to minimize the effect of
each mutation on the phenotype.
True/False: Opposition to irrational numbers was
based on evidence that such numbers cannot exist.
False; (No direct evidence for or against irrational
numbers was used to oppose the idea. A religious
belief based on faith was used instead.)
True/False: Opposition to irrational numbers
stemmed from a worldview involving naturalistic
evolution.
False
