Chapter 15 Definitions
The fluid portion of unclotted blood.
Plasma
These three items are what is suspended in plasma.
Red Blood Cells (Erthrocytes)
White Blood Cells (Leukocytes)
Platelets
These are the two types of DNA.
Mitochondria DNA (mtDNA) and Nuclear DNA
A rodlike structure in the cell nucleus, along which the genes are located; it is composed of DNA surrounded by other material, mainly proteins.
Chromosome
____, usually proteins and carbohydrates, are located on the surface of red blood cells and are responsible for blood-type characteristics.
Antigens
The clumping together of red blood cells by the action of an antibody.
Agglutination
These are the three colors tests used for blood.
Kastle Meyer
Luminol
Blue Star
These are the four bases that compromise a nucleotide.
Adenine
Guanine
Thyomine
Cytosine
Polymers of amino acids that play basic roles in the structures and functions of living things.
Proteins
This accounts for 55% of blood content.
Plasma
Having two different allelic genes on two corresponding positions of a pair of chromosomes.
Heterozygous
There are __ chromosomes in a normal human cell.
46 (23 mated pairs)
STRs normally consist of repeating sequences of ____ bases in length
3 to 7
Small structures located outside the nucleus of a cell; these structures supply energy to the cell; maternally inherited DNA is found in these.
Mitochondria
mtDNA
Having two identical allelic genes on two corresponding positions of a pair of chromosomes.
Homozygous
Genes that influence a given characteristic (such as eye color or blood type) are known as _____.
Alleles
_____ is the number of STRs required for a CODIS entry.
20 (13 prior to 2017)
A region of a chromosome that contains multiple copies of a core DNA sequence that are arranged in a repeating fashion.
Tandem Repeat
The gene for tooth pulp.
Amelogeinin Gene
A protein that destroys or inactivates a specific antigen; are found in the blood serum.
Antibodies
The two antigens found in O-type blood are ____ .
Y-STRs are only found in _____.
Males
A technique for replicating or copying a portion of a DNA strand outside a living cell; this technique leads to millions of copies of the DNA strand.
Polymerase Chain Reaction (PCR)
Match this STR of base pairs
A - T - C - C - G - T - T - C -A
T - A - G - G - C - A - A - G - T
