Many species of corals (an invertebrate animal) thrive in nutrient poor tropical sea waters due to a mutualistic relationship with a group of green algae called zooxanthellae that live only inside the corals. The coral host uses the photosynthetic products produced by the algae. These corals are not found below 100 feet depth in the ocean. Why?

the red, green, or yellow light that the zooxanthellae require to perform photosynthesis does not have enough energy to penetrate the water any deeper than that. Since the coral rely on the these micro-organisms, it will not grow where they can not survive.

In polygynous mammals (one male mating with several females) such as lions and gorillas, when a new male takes over a harem, he quickly kills all the young of the females in the harem as his first act of becoming king of the harem. What hypothesis might explain this barbaric behavior?

want to get rid of genes other then his own
dominance
do not want to be taking care of other?s young. Only want their genes to be passed onto the next generation.

What is a good way to measure your Basal Metabolic Rate (BMR)?

blood pressure pump, sphygmomanometer, systolic over diastolic, taking your blood pressure in the morning because you have not really done any activities yet

what is BMR

how many calories you burn if you were to lay in bed all day

Where does replication take place ?

inside the necleus

DNA contains

the instructions for producng the heritab traits of ALL SINGLE CELLED ORGANISMS!

what does DNA consist of?

sugar
phosphate
nucleoties

sugar in the DNA does what

forms skeleton
backbone

phostphate in theDNA does wat

attachs nucltides tosugar skelteon

nucleotide is the DNA does what

bases whose sequences produce coded messages

chromosome pairs

are homolagous

gene locus

location of a particular gene

pair of alleles

moleclar form of a gene at a given locus

for kinds of necleotes in DNA

adenine
cytosine
guanine
tymine

where does DNA rep. take place?

entire chromosome

mitosis

wen chromosomes are double befrecellssplit in two

as long as the doule helix is in tact

there i no duplication

step 1 of mitosis

ENZYME unzips entire chromosome. The A's and T's are deperated

step 2 of mitosis

the free unnached nucleotides comee from the nucleus and line up and connect

step 3 of mitosis

other enzymes serve as DNA glue t zip one parental DNA strand tgetherwith its newly synthesized daughter strand an wind togetert for their own double helix of DNA

what is the mistake probablitity?

1 in 100 million

what are mistakes in mis mtched nucleotides called?

mutations

DNA is a book of

instructions in each cell

genome is the what?

cell information

how do the lettters and istructions give rise to sentences?

protiens!!

what are protiens?

chains of amino acids

how many protiens are there

millions

how many different types of amino acids are there

how can just FOUR types of bases in DNA encodeall of the information needed to produce ten of thousandsof protiens, each wih various combinations of 20 amino acids?t

one GENE codes fo th amino acid sequence that produces a specific protien such as an enzyme

a DNA molecule itself contains no

protiens

transcipion

coded message of base sequence frm unwound DNA strand transferred to RNA

RNA is

ribonucleuic acid

RNA strand is assemly similar to DNA through rules of....

base pairing

in rna all the bases are present besides thymine and it is replaced by...

Uracil

Uracil pairs with

adenine

unwound ___ serves as a template to form RNA

DNA

transcription results in a single free strand of...?

RNA

translation

actual conversion of message from nucleotide sequence ino a protien

protiens are all constructed of building blocks called...

amino acids

nucleotide base sequenceof RA are read in gorups of three in a row-- each triplet of bases is called a...

Codon

How is DNA the unity of life?

we all have it :)

How is DNA the diversity of life?

TINY differences make us different species

why not use a quaret or quinet of neighboring nucleotides to represent each amino acid?

Too much energy

DNA = T_________

TRANSCRIPTION

RNA = T______-

TRANSLATION

A TRANSLATION EQUALS A...

PROTIEN

MUTAGENS

enviromental agents that interact with DNA to cause modifications

a mutagen can cause or create

a virus, ultraviolet, chemicals

spontaneous

replication errors

uncontrolled replication is...

cancer

aging may be caused by an accumulation of DNA erros and..

mutations built up

aritificial selection has an example of

glasses

how are surgery, transfuson,vaccnations ad drug therapy mechaism for artificial selection

we can pass on our bad genes

recombinant DNA is

insulin, human gene therapy= genetic engineerin

bacteria can help do what

create insulin

GM foods

there are no proven health effects
may be bad for ther enviroment

why doesnt the violet go down to the deepest?

the wave length is SO TNY

Someone has submitted a proposal that claims there are super carnivores to be discovered in an unstudied part of the Congo Basin. These super carnivores supposedly feed on lions and leopards. You are on the panel to judge if this proposal should be funded or not. What argument would you best use to decline this proposal and not fund it?

according to the 2nd law of thermodynamics, the higher up the foodchain you go the less energy will be converted

Where do the new nucleotides come from to form the new strand of DNA during replication?

In the cell there are FREE and unattached nucleotides that are drawn from the cellular pool and attach themselves to the exposed nucleotides on each of the unzipped single DNA strands.

Insects and many medicines are connected by what line of logical reasoning?

plants give off toxins to keep insects away and from eating them but these toxins can actually help humans with medical discovories in medicine

What is the basis of the controversy about stem cell research?

The theologians believe that this manipulation is act against nature or god himself and that man was never meant to tamper with the forces that are responsible for creating life.

Why do doctors use high amounts of electricity to stop the heart when a dangerously arrhythmic beat develops?

beats of the healthy human heart produce small electrical beats .
the large ammount of shock is used in hopes to stopthe heart and let it restart pumping on its own agai

What adaptive value can stem cells have?

they are undifferentiated, having no particular form or function, until they are needed. When they are needed they ?guided? through a process of differentiation where they are given a specific form and function

where does transcripton take place?

the nucleus

where does translation take place?

outside the nucleus

what is the pupose of translation?

to form newprotiens based on info.

how does DNA differ from RNA

DNA = doublehelix, adenine,deoxyrose

is rna a single or double helix

single

Why are codons read in series of three neighboring nucleotides

They tend to grouped in threes or triplets because this allows for a single triplet to be able produce multiple types of protein depending on the sequence of the nucleotides.

What does a codon represent?

The codon represents a triplet of nucleotides, which depending on their sequence, correlate with the formation of a specific protein.

Why doesn?t the DNA just make the protein directly

it only contains genetic info. on how to form proteins, not the ability to produce them.

How much protein and amino acids are on the DNA or RNA

they dontcntainprotien or aminoacids. RNA used amino acis to form protien cains

how canbacteria produce human insulin?

recombinant DN
