| What did Hugo Dooner study? |
|
Definition
|
|
Term
|
Definition
| A DNA sequence that prevails between members of the same order/gamily/genus |
|
|
Term
| The more ______ the ancestral relationship, the higher the degree of conservation |
|
Definition
|
|
Term
| A highly conserved gene (traces far back in evolutionary history) is likely (essential/nonessential) for function |
|
Definition
|
|
Term
|
Definition
| 3-4 genes surrounded by long stretches of repetitive DNA |
|
|
Term
| What are long-range control elements (LRCE)? |
|
Definition
| unique sequences, function is unknown but thought to control/effect phenotypic expression indirectly |
|
|
Term
| What 4 prevailing thoughts did the Fu & Dooner paper disprove? |
|
Definition
-repetitive DNA is not highly important
-SNPs are very common, major source of genetic variation
-sequence variation is less common
-loss of gene order within a species is almost non-existant |
|
|
Term
|
Definition
| To determine the base pair order along a sequence of DNA |
|
|
Term
| What is the difference in gene content between two individuals? |
|
Definition
|
|
Term
| How often do crossover events occur in corn? |
|
Definition
| -once per chromosome arm (2x/chromosome) |
|
|
Term
True or False
crossover in pigs occurs more often in females than in males |
|
Definition
|
|
Term
True or False
the less homology there is between chromosomes, the more recombination occcurs |
|
Definition
false
MORE homology = more recombination |
|
|
Term
| Does recombination occur in hemizygous or methylated regions? |
|
Definition
|
|
Term
| What is the 'wobble' position |
|
Definition
| The 3rd nucleotide in a codon |
|
|
Term
| What is the effect of a SNP in the 'wobble' position? |
|
Definition
| Potentially might not change the amino acid that is being coded for |
|
|
Term
| Where is genetic material found? |
|
Definition
In the nucleus (chromosomes)
In mitochondria (cytoplasm) |
|
|
Term
| How is genome size measured? |
|
Definition
In # of doouble stranded base pairs
OR
the mass (in picograms) of 1 copy of the genome |
|
|
