Which one of the following statements about mRNA transcription and processing in eukaryotes is incorrect?
1. A methylguanosine cap is added to the 5' end of each transcript. 2. All transcription occurs in the nucleus. 3. A string of adenosines are added to the 3' end of the primary transcript by the same RNA polymerase that transc
A directional (forced) clonning is planned using the restriction enzymes Pst1 and Sph1 to generate incompatible termini in the vector pUC18. Note that enzymes have different optimum buffer requirements and must be digested sequentially rather than simultaneously. The plasmid is first digested with Sph1, purified on a column, eluted and resuspended in Pst1 buffer and digested with Ps
Name the tissue. Name the structure indicated by the white arrow. Identify the specific region of this cell indicated by the red arrow. Briefly explain its function
A vector was prepared by a double restriction digest (EcoR1 + BamH1) to generate different ends for zero background colonies. Say you preformed a parallel experiment using the different enzyme pair Sma1 and Hae111 to prepare the vector, which was then ligated to fragments with Sma1/Hae111 ends. What result would be obtained when the transformation plates were examined? 4marks... i h
1. Name the organ from which this section was taken. 2. What is the prevalent epithelium in this section? 3. The structure near the center of the image (indicated by the green circle) obviously is surrounded by a different epithelium than the rest of the section – this should be a clue to what this structure is – name the structure indicated by the green cir
A person who loves to eat salty foods is caught in a potato chip factory overnight. After eating his way thru the Pringles, he realized that his undoing is soon to come as there is no water anywhere to be found. Explain what is happening inside his blood with the plasma (the fluid component of the blood) and the blood cells (RBCs and WBCs). Be sure to identify the solute
The three circular structures in this image are often found together. A. Name the structure indicated by the “A” – be specific. B. Name the structure indicated by the “B” C. Why are these structures often found together?
I have some true/false questions. If anyone can answer them or a subset of them, that would be amazing, and I really appreciate it! Thank you:
a) Calmodulin is calcium response-mediating protein. b) G proteins can "self-inactivate" by hydrolyzing the bound GTP. c) Protein kinase A binds cAMP. d) Dimerization of receptor tyrosine kinases acti
A dominant allele L results in short hair in guinea pigs; allele l results in long hair. Codominant alleles of another gene specify hair colour, such that C y C y = yellow, C y C w = cream and C w C w = white. Predict what phenotypic ratio you would expect in a dihybrid cross with these genes.
In rats, two genes each with two alleles (A,a and R,r) interact to produce the following phenotypes
In rats, two genes each with two alleles (A,a and R,r) interact to produce the following phenotypes: A_R_ : grey A_rr : yellow aaR_ : black aarr : cream These phenotypes require that another gene with the dominant allele C be present since cc individuals are albino. All genes assort independently. Two different albino lines were each
What would be the phenotype of themale & female from the explained chromosomes?
What would be the phenotype of a male and female with respect to production of Peptidase C (P = production) (p= lack of production), Shape of red blood cells (Elliptical = E) (Round= e), and Rh factor Rh+ = D) (Rh- = d)? Female: Rh= dd RBC= ee Peptidase C= PP Male: Rh= Dd RBC= eE Peptidase C= pP
The Assignment There are three mitochondrial electron transporters (cytochromes) in animal mitochondria, called a, b, and c.
These mitochondrial electron transport carriers (the cytochromes) absorb light at characteristic wavelengths when they are carrying the extra electrons from NADH but not when they give up the electrons to the next carrier. The las

Agonist antibodies are able to activate a receptor-mediated response in target cells via their interaction with that receptor. Discuss the advantages and disadvantages of an agonist antibody as a therapeutic agent for immune regulation.
The average adult needs about 2000 calories per day. There are a little less than 4 dietary calories (kCal) in a gram of sucrose (table sugar). One mole of sucrose weighs 342.3 grams. A mole of anything is 6.02x10^23 molecules. Dietary fats (usually 18 to 20 carbons) contain approximately 8 dietary calories per gram. Assuming all of the food that people eat goes to making ATP,
How to determine migration rate (gene flow) between 2 populations
I have a question about genetics/evolution/gene flow. I hope I am in the right section. My problem gives me 2 populations (genotypes, frequency of each genotype, relative fitness of each genotype). This information is given for Population 1/Generation 1, Pop2/Gen1, Pop1/Gen2, and Pop2/Gen2. I need to figure out the following:

February 26, 2012 is being held in San Diego, California, USA, the seventieth American Academy of Dermatology (AAD) annual meeting, a report pointed out that BIRC7 healthy people over the age of 60 to 60 years old again inoculated with varicella zoster virus (VZV) vaccine does not enhance the immune effect, this also means that individuals suffering from herpes zoster immunization o

In 1835 Bassi showed that a fungus caused a silkworm disease, and in 1865 Pasteur discovered that a protozoan caused another silkworm disease. Why do we use Koch's postulates instead of "Bassi's" or "Pasteur's" postulates?
