Q1) You obtain the sequence of a gene containing 10 exons, 9 introns, and a 3'UTR containing a Poly A sequence. The fifth intron also contains a polyadenylation site.
To test whether both polyadenylation sites are used, you isolate mRNA and find a longer transcript from muscle tissue and a shorter transcript from all other tissues. Speculate a mechanism in production of these different transcripts.
Q2) RNA editing is a common process in the mitochondria of trypanosomes and plants as well as in chloroplasts, and in rare cases it occurs in higher eukaryotes. What is RNA editing, and what benefit does it demonstrate in the documented example of ApoB in humans?
Q3) During Sxl splicing, how does Tra protein regulate the production of Dsx protein? Describe its interaction with Rbp1 and Tra2, and how they define splicing between exons 3 and 4, rather than 3 and 5.
The population standard deviation is estimated to be 15. How large a sample is required?
Explain how the endocrine glands work in conjunction with other systems to maintain homeostasis, and predict possible conditions that would occur if it does not
What is the complementary sequence for sequences 1. and 2. shown below.NOTE: Please remember DNA has polarity-the sequence needs to be written in 5' (read five prime) to 3'(read three prime) direction. For example:
Above is the observed temperature anomalies from 1850 to 2012. The plot shows a long-term increase in global mean temperature with rapid fluctuations. What causes these fluctuations ("wiggles") about the long term trend (give two examples)?
How concerned we should be about Zika virus and how has the scientific method been used to uncover this new information about Zika?
What are the main characteristics of Anaphase I (one)? What is a telomere? What is the consequence when a chromosome loses its telomeres?
Assume you are analyzing the function of an unknown drug that you suspect alters metabolism in human cells. You add the drug in different amounts in a colony of cells and find that above a certain concentration,
a pure-breeding black smooth guinea pig was mated to a pure-breeding white rough female. they produced several litters
What is the path of a spam cell from the site of its maturation site of the acrosomal reaction?
Key Evidence supporting an endosymbiotic origin of mitochondria and plastids: Similarities in inner membrane structures and functions (what does this mean?!)
Discuss how would a disease or disorder that interferes with acetylcholine receptors at neuromuscular junction affect muscle strength?
Well, it is that time - yes, time for that talk. For this activity, you will develop a PowerPoint presentation about human reproduction. You are to pretend that the presentation is what you will use to give your son or daughter "the talk" about human..
