Definition
a protien that premits the uptake of glucose.
Term
Genotype
Definition
an individuals uniques gentic makeup; determinded by DNA sequence anylsis.
Term
Phenotype
Definition
An individuals observable features/ mesaning of the gene.
Term
What can be used to identify and individual?
Definition
Genotype
Term
What has the potential to change phenotype
Definition
A change in genotype
Term
Where do deiases have roots in?
Definition
Genes
Term
loss of function mutation.
Definition
gene product having less or no function
Term
Gain of function mutation
Definition
Gene prodduct gains a new + abonomal function.
Term
What ius a mutation?
Definition
A inherited change in the genetic code of the gene.
Term
Single base-pair change
Definition
chemical changes in the nucleotide (a--->c).
Term
Deletion
Definition
removal of one or more nucleotides.
Term
Insertion
Definition
Addition of 1 or more nucleotides
Term
Inversion
Definition
an entire section of the DNA is reversed
Term
Chromosomal abnormalities
Definition
Change in chromosome # or structure.
Term
Dominate Alle
Definition
prevail in dictating phenotype.
Term
When does a recessive alle become apparent?
Definition
when the other chromosome becomes inactivated or lost.
Term
Homozygous
Definition
two identical allels
Term
herozygous
Definition
two different alleles for a gene.
Term
Autosomal dominat disorder
Definition
when the diease causing gene is a dominat allele. Nees only one dominat allele to have the gene.
Term
if the parents are _1_or_2_ what is the percent chance the child will have the diease? 1. Dn nn 2. Dn Dn
Definition
1. 50% chance bc the childern will be Dn Dn nn nn

2. 75% chance bc childern will be
DD Dn Dn nn
Term
Autosomal recessive disorder
Definition
when the deiase casuing gene is a recesive allele.
Term
signs and symptoms of inflammation
Definition
redness,swelling, heat, pain, loss of function
Term
What is inflammation at the cellular level
Definition
cell damage response
Term
what is Acute inflammation:
duration
healing
examples.
Definition
-short duration minutes to days
-complete healing with new cells, remodeling of collages, removal of dead cells

ex: skin cut, cold
Term
What is chronic inflammation:
duration
healing
Examples
Definition
-long time, months to years
-ongoing repair, permeant scaring of tissue
-tuberculosis, Bronchitis
Term
What is inflammation and its purpose.
Definition
The response of living tissue to damage.
It purpose it to deliver defensive material to the site of injury.
Term
What is the mechanism for Inflammation
Definition
1 Initiation
2 Amplification
3 Termination
Term
What is initiation of an Inflammatory response
Definition
a stimulus physical, chemical, bioligical
Term
What is initiation of an Inflammatory response
Definition
a stimulus physical, chemical, bioligical
Term
What is Amplification
Definition
mediated by cells, amplified by chemicals, may cause tissue damage!! magnitude depends on the nature and duration of stimulus
Term
Termination
Definition
inflammation persist until the stimulus is removed before healing can begin
Term
Vasodilation
Definition
dilation of blood vessel near site of injury, due to smooth muscle
Term
Permeability of vessels
Definition
opening of gaps in blood vessels. result in leakage fo protein and H2O
