DAT-256-301 Flashcards
most abundant RNA
r-RNA 80%
least abundant RNA
m-RNA, turns over rapidly
smallest of the RNA
t-RNA; transport amin acids to ribosomal site
zygomycetes, basidiomycetes, lichen, ascomycetes
types of fungi
amount of blood in average size adults
5 quarts
alubumin
important for maintaining the bloods osmotic pressure
stigma
sticky part of flower that catches pollen
bonds between antibodies
disulfide
blood clotting
involves a series of chain rxns in which fibrinogen is converted into fibrin
fibrin
form a mesh that traps RBC to become a solid barrier to blood loss
yields most energy
fat
what transfers electrons to the ETC
FADH2 and NADH
NADH yields ; each FADH2 yields
3 ATP; 2 ATP
mullerian mimics
(bees wasps ) contain some yellow warning colors that alert predators not to attack
batesian mimicry
deceptive mimicry; family of bees that resemble yellow bees but don’t sting at all.
stem cells in the bone produce lymphocytes by
mitotic division
two parts of immune system
antibody mediated immunity (regulated by production of B cell antibody production) and cell mediated immunity (regulated by the T cells (mature in thymus)
emphysema
pathology marked by the destruction of alveoli
in-vitro fertilization
fert between an egg and a sperm in a glass dish in the lab
micro-injection
technique that involves directly injecting the sperm cell into an egg
promoter region in eukaryotes which contain group of nucleotides is called a
TATA Box ; regions aren’t rich and AT
promoter region in prokaryotes which contain group of nucleotides is called a
Pribnow box
on and off switch control point for translation
operator
operon
assemblage of operator, promoter, and structural genes
5 classes of immunoglobins
IgD, IgA, IgM, IgE, IgG
erythroblastosis fetalis
Rh- mother, Rh+ fetus(produce the Rh antigen)
egg cell has how many chromosomes and chromatids
23 chromosomes, 23 chromatids
small DNA binding proteins that allow DNA coiling are
Histones
complement
a chemical defense system that works with the immune response and supplements the inflammatory response
most breif mitotic stage
anaphase - centromeres spit and daughter chromosomes begin to seperate
synapsis
occurs in prophase I of meiosis ; we see the pairing of homologous chromosomes .
formation of new species due to geographical isolation
allopatric speciation
sympatric speciation
if speciation occurs after ecological, genetic, or behavioral barriers arise within the same geographical boundary of a single population
founder effect
a new pop arises because of a single individual or a few individuals causing a change in allele frequency
protosomes
mollusk, arthropods, annelids; the opening of the first indentation becomes the mouth
echinoderms and chordates
deutorosomes
oncotic pressure vs. hydrostatic pressure
oncotic pressure pull fluid into capillary; hydrostatic pressure tends to push fluid out of a capillary
inactive form of enzyme
zymogen
cytochromes
group of heme containing proteins found in the ETC
order of eras
Cenozoic (now) > mesozoic (dinosaurs) >paleozoic (plants)>precambrian (fungi )
second messenger
cyclic amp; activates enzymes; initiates protein synthesis even alter membrane permeability
