The final step of the cloning procedure is to screen the plasmid library for clones that carry the vgp gene, shown in red below.
To accomplish the screening, researchers synthesize a single-stranded DNA probe using vgp mRNA as a template. What will be the sequence of nucleotides in the probe?
Drag the labels to their appropriate locations in the probe. Labels can be used once, more than once, or not at all.
in what ways is genomic imprinting similar to X-inactivation in what ways are the different.
Prader-Willi syndrome is caused by the deletion of the paternal copy of a small section of human chromosome fifteen. In normal individuals, only the paternal copies of the genes in this section of chromosome fifteen are expressed;
Modern theory suggests that the early pre-life atmosphere on Earth was a reducing one. Why is it believed that oxygen was not present as life formed on Earth.
When DNA samples A and B were separated by buoyant density centrifugation the 2 samples migrated 23 and 15 cm, respectively. If DNA B had a GC content of 34%, what was the GC content of DNA A.
If the three enzymes of the pyruvate dehydrogenase complex existed as three separate proteins rather than a complex, would this slow the rate of reactions catalyzed by these enzymes?
In cells, the phosphorylation of glucose is the first step in glucose metabolism and is accomplished by addition of phosphate from ATP which generates ADP and Pi (G° = -7.3 kcal/mole). Therefore, in the cell there are two reactions coupled togethe..
Jake, a surfer-skier dude moves suddenly from low to high altitude for the winter skiing. Upon arrival he is hyperventilating in response to the altitude.
A membrane which is permeable to an uncharged molecule X separates two solutions. Solution A contains a 100 mM solution of X and B 10 mM. If the permeability constant for X is 5 cm/s.
gene A controls the sharpness of spines in a type of cactus. cactuses with the dominant allele, A, have sharp spines, whereas homozygous recessive aa cactuses have dull spines. at the same time, a second gene, N, determines whether cactuses have s..
The enzyme Bromelin is a cysteine protease from pineapple that utilizes a similar mechanism to serine proteases except the serine is replaced by a cysteine. Draw the mechanism of peptide hydrolysis by Bromelin.
If we observe that domestic turkeys are less resistant, does that necessarily mean that wild females had been choosing more-resistant males, or are other hypotheses equally plausible? Please include at least one scientific research article to supp..
Discuss the process of natural selection as defined by Darwin. How did Darwin's theories differ from his predecessors?
