What is a change in DNA code?
A change in gene level at DNA level can be characterized into two different categories. The first is called a base substitution and the second is called a base addition.
Name two major types of mutations?
Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
What is trans heterozygous?
Trans heterozygous is a diploid organism that is heterozygous but it has two different loci(genes). They each have one natural allele and allele that is different from the natural allele due to a mutation.
During DNA replication two extra guanine bases are added to the DNA. What type of mutation is this?
frameshift mutation
If you compare the original DNA to the two copies that are made after replication occurs what would you find?
Unless mutation occur the two copies of DNA that are made after replication are identical to its original form. Thus continuous replication of DNA in the chromosomes does not alter its nature.
How can twins occur?
I know of two ways. Maybe there are more, but first the egg is fertilized and then it splits, and second, two different eggs are fertiglized.
What is the multiplication principle?
If one event can occur in "m" ways and a second can occur independently of the first in "n" ways, then the two events can occur in "mn" ways.
What does two daughter cells with different DNA represent?
a mutation
What are two ways transmutation can occur?
t
What is the dual processing being revealed by today's cognitive neuroscience?
dual process theory provides an account of how a phenomenon can occur in two different ways, or as a result of two different processes.
What 2 ways does it vaporization occur?
the two ways are evaporation ans vaporization
What is the product of 117 in two different ways?
write the product of 117 two different ways
List two ways in which your teeth are different?

Why are male mutation rates higher than female?
This is because mutations occur in x chromosomes. The male, who has "xy" sex chromosomes, will have the mutation if it is present in the x chromosome. Females, there is a smaller chance because there are two "xx" chromosomes, which reduces the chance that the mutation will be present.
What is sequential mutation?
It's a double mutation that occurs on a colony of cells (bacteria for example) that claims to have resistance to two different antibiotics or viruses. This double mutation, however, strictly happens by first developing a mutation for the first antibiotic/virus and then has an independent mutation (nothing to do with the first mutation) for the other or second antibiotic/virus.
Define counting principle?
If one event can occur in m ways, and for each of these a second event can occur in n ways, then the number of ways that the two evens can occur together is m x n. Can be extended to three or more events.
Why do different mutations accumulate in two species once they diverge?
Because they can no longer mate and swap the mutation
