As an undergraduate I majored in Anthropolgy (mostly biological anthropology and human evolutionary ecology) and also alot of evolutionary psychology classes. I also know calculus and am very strong in statistics. I only took 8 hours each of chemistry and biology though. I was always interested in evolution’s implications on humans, but am now thinking that I would rather go to Grad school to study genetics and evolution itself.
Could I be admitted directly to a biology program with this background our am I doomed to studying humans unless I make up these undergrad defeciencies?
How does cloning, the human genome project, ethical/ social/ legal issues in genetics, stem cells (embryonic and adult), genetic fingerprinting/ forensic science and DNA, gene therapy, genetically-altered agricultural product/ genetically modified food? Thanks
Why do signaling responses that require changes in proteins already present in the cell occur in milliseconds to seconds, whereas responses that involve changes in gene expression usually require hours?
I just cannot figure out an answer that makes sense. I would appreciate some help!
I’m interested in two things that don’t seem to have a good undergraduate program, seeing as theyre so specific. so I guess I’ll have to further continue them in undergraduate studies. I really like biological sciences, especially genetics and microbiology. I’m also interested in history and the development of human culture. I want to study the history of medicine, but in order to do that, what should I focus on as my undergraduate major, history or biology?
What are the simplest answers and definitions to these questions?
Describe the general structures and functions of DNA, RNA, and protein.
Show how base?pairing rules explain accurate copying of DNA during semi?conservative replication
Show how base?pairing rules explain transcription of information from DNA into mRNA.
The general pathway by which ribosomes make proteins, using tRNA’s to translate genetic information in mRNA.
Show how the genetic coding rules predict the sequence (order) of amino acids from a sequence of codons in mRNA.
Explain how mutations in the DNA sequence of a gene may or may not affect the gene expression, or the sequence of amino acids in an encoded protein.
Specialization of cells in multicellular organisms is usually due to different patterns of gene expression rather than to diffrences of the gene themselves.
Proteins can differ from one another in the number and sequence of amino acids.
How genetic engineering (biotechnology) is used to produce new biomedical and agricultural products.
So a little family history, to kinda help set the question.
my grandpa, mothers side, had a bad heart. He started showing some major problems in his early twenties. About 28-30 he had a heart attack, and it almost killed him. 35 he had a stroke, and 37 and 38 he had 2 heart attacks. about 50 some he had a fatel heart attack, and a stroke along with it. we were told it was the end. he recovered almost completely, then one last stroke and massive heart attack at 57, he couldn’t come back and passed away at 62…
My aunt, still my moms side, is diabetic, my mother has extremely bad kidneys, and her blood is to thick, shes had a bunch of clots.
and depression is strong on both sides.
my sisters and my little brother have it.
my one sister has scolios, and my other sister has pretty severe migraines, my little brother has seizures, absence seizures i think is the name…
not that I’m complaining but, I don’t really have anything. I’m kind of afraid of what i may inherit, does anyone know that odds, or signs, or something. I dont even know what im at risk for, or how long i have to live
with all that, am I screwed…
many factors influence gene expression, including hormones. The use of anabolic steroids and growth hormones among athletes has created controversy in recent years. Hormones certainly affect gene expression, but, in the broadest sense, so do vitamins and foods. What do you think are appropriate guidelines for the use of hormones? Should athletes take steroids and growth hormones? Should children at risk of being unusually short be given growth hormones? Should parents be allowed to request growth hormones for their children of normal height in the hope of producing a future basketball player?
I want to do a course that is more into the human biological area.
Something like genetic engineering but i don’t know what course you have to do to be able to work in a field like that.
What i just want to do, is i want to help people. by making them more stronger. so i want to deal with the human genetics and altar/improve/repair DNA structure. leading to positive effects.
I’m not entirely sure which course does this sort of thing.
Please Help
Thanks
Human Biology
Can anybody help me with these questions for a review quiz. I couldnt find the anwers in my book.
1.Which of the following can regulate gene expression in eukaryotes?
A.lac operons
B.transcription factors
C.plasmids
D.lipids
2.Gene expression can occur at several points along the pathway from DNA to RNA to proteins. In one example of gene expression, the protein insulin must be trimmed to a smaller size. How is this is an example of gene expression?
A.Until the protein is trimmed, the shape of the DNA blocks transcription.
B.Until the protein is trimmed, transcription is blocked by a repressor protein.
C.Until the protein is trimmed, it is not useful to the cell.
D.Until the protein is trimmed, the ribosomes are not active.
3.If a cell loses control of gene expression, what happens?
A.The cell becomes more specialized.
B.The cell can carefully use its resources.
C.Healthy, mature cells develop.
D.Abnormal, unhealthy cells develop.
Given that the distance between two nucleotides in DNA is 0.3 nanometers, what is the length of the DNA in a human ***** cell? What is the average size (number of amino acids) of a human protein (please give reference)?
