CNA,CMT,LPN,IV therapy course, next got married inherited trust fund paid for books/tuition to school went back premed biology major, worked hard got divorced... got published... did field biology La selva, HIMB,... graduated Dec 2006.. now what? cant find lab work or research work w/ just my BS nothing but maybe some quality control work that pays nothing... working as LPN makes more... should i go to grad school.. bio, path, immune, cellular bio... undergrad research doing PCR, RFLP,RAPD... havent taken MCAT did less than stellar on GRE lol but didnt refresh my highschool geometry prior to taking it... all education is paid no matter where i go or what i do... but now inbetween school and work.. and not sure what path i should take now... GPA was good perfect until last semester and divorce/house fire... but still above average... honors level undergrad reseach and good references.. Live in midwest now... have daughters willing to relocate if necessary looked into several grad progrm

Family Tree Report



Introduction:
“Rosacea is chronic skin disease that causes redness and swelling, primarily on the face.” I picked this trait because it is probably different from any of the traits other students picked. I wanted to learn about this trait because I could get it when I come to age of it, although it is not threatening to life. I wanted to learn about this and see some of the symptoms, genetic bases, and history of the trait.

Discussion of the traits:
A. Symptoms, conditions, and characteristics
Your cheeks, forehead, and nose all get affected by this disorder. They turn red and swelled. Your nose can enlarge and you can get pimples. Your cheeks can also seem like spidery veins. It is triggered by hot drinks, tobacco, alcohol, spicy food, exercise, stress, infection, vitamin deficiency, and extreme heat/cold. It may be cause by environment, disorder of blood vessels, mites/bacteria, infection, or most of all genetics. The true cause is unknown. It occurs mostly in white Scandinavian, Celtic, and Caucasian women from age 35-45. It can occur in men, but it is more severe if it does.
Treatments could be an immunosuppressant such as Tacrolimus.
B. Genetics Basis
As mentioned before Tacrolimus could be a treatment. It slow down record of genes that encode certain stages of T cell activation. It seems like it could be sex-linked since women just get it, but men sometimes get the symptoms too. It seems like you do or you don’t get it meaning it may not be polygenic, but if it wasn’t then scientists would have more than likely figured out the cause of it already. Some scientists are searching for way to find the solution genetically. Sine if them took skin samples and used a gene scanner to identify 21,000 genes (50%-60% of genes in human genome) to study.

Inheritance factors of the trait:
A. The women seem to have it, not the men. It does not show up until ages 35-45, so it is hard to tell who may have it and what genotypes, each person has for it. It is definitely on my mom’s side of the family, because my aunt (mother’s sister by blood) has it too. Also I do not know very much about my dad’s side of the family. So far everyone around the age 35 or up starting form my grandmother, down has had the disorder.

Appearing in children:
A. If it is a genetic disorder, it is likely that it will be in my children, if they are females. We will not know right away though. As said before, it has showed up in every women from under my grandmother old enough to show the phenotype of the disease.

When creating a transgenetic organism using cDNA (DNA compliment) Is it necessary to include the introns and promoters? Or do I rely on the organism's own DNA regulatory sequences? Basically, I would like to know if transformation of a gene is possible with the sequence from cDNA alone, or if the genomic DNA sequence is needed?

In Drosophilia, the genes st( scarlet eyes), ss (spineless bristles), and e (ebony body) are located on same chromosome. with map positions

st- 44 --------------- ss-58------------------------e- 70

Each of these mutations is recessive to the wild type allele. (st+, reddish-brown, ss+, smooth bristle, and e+, gray body)

Phenotypically wild type females (st ss e+/ st+ ss+ e) were crossed with triply recessive males

a. what is the probability that the female will produce a gamete with the allele combination st+ ss+ e+? Assume no interference... (hint work it backwards step by step)

b. predict phenotypes of the progeny of the parents given and the frequencies with which they will occur assuming a level of interference at .4

I know how to do a 3-point test but don't understand the work backwards part... ANY help greatly appreciated!

i am studying biotechnology and i get confused of those two kinds of gene transfer. the first one belongs to direct transfer, the second one belongs to indirect (mediated) gene transfer. but what the difference?

For example: The blue-streaked wrasse and the oriental sweetlips. The sweetlips is a fish with teeth, and the only way that those teeth keep from rotting off is is to stay clean. How do they stay clean? the blue streaked wrasse enters its mouth and eats the stuff off it. Well, in order for this to happen, they would both have to develop these instincts at the same time. The instincts would have to develop at the same time as the sweetlips' teeth. If one of these didn't develop, the system wouldn't work, and the sweetlips that had teeth would all die. You gotta admit, there are too many coincidences here to have happened by chance. Admittedly, there are some symbiotic relationships that you could explain, but there are others simply too complex to to throw in the hands of fate.
