Under normal conditions, what stimulates the release of somatostatin from Antral D-cells? -The decreased presence of D-cells relative to other cell types within the stomach is accompanied by measurable increases in gastric acid production, and a decrease in luminal pH

Assuming all are approximately 8 nucleotides in length, which of the following would be effective as primers during the reverse transcription step of the experiment described above? 1. A multitude of random, scrambled primers 2. Primers specific to the first intron of POMC 3. A string of thymine nucleotides 4. The same set of primers as used in the PCR amplification step
1. The reverse transcription step of this experiment requires that at least one POMC mRNA yield a complementary cDNA. In other words, this step does not require specificity. PCR amplification will exponentially and specifically multiply any POMC cDNA generated. Therefore, with enough random 6 - 8 nucleotide primers, one would expect to amplify at least a small fraction of POMC mRNA. 2. no bc introns not in mRNA 3. yes bc mRNA has poly A tail that thymine can bind to to reverse 4. Yes bc these are spec to the cDNA so will also bind to desired spots on mRNA
A high diversity of antibodies is an essential part of a healthy adaptive immune system. Which of the following contribute to antibody diversity? 1. point somatic hypermutation 2. point gene fragment rearrangement 3. Junctional flexibility 4. point affinity maturation

Suppose that researchers chose to assay IDH enzyme activity using the exact same methods as stated in the passage, except that a cell line derived from a GBM patient harboring the IDH mutation was used in place of the cell line used in the original experiment. What changes would one most likely find with respect to the results depicted in Figure 2? (vector+WT highest NADPH, just vector and vector+mutant much lower when vector contained IDH) A. Reduced NADPH concentration in the "vector + wt IDH" group; no measurable NADPH concentration in the "vector" and "vector + mutant IDH" groups. B.

It will be much larger. C. It will be smaller. C. It will remain the same.
C. after weeks of infection almost all of the antigen is bound and the antibody will have developed a strong affinity for the antigen so Kd is small
A hypothetical study hopes to determine the epidemiology of osteoporosis and ARO in the United States, and attaches a survey to an annual political election ballots routinely over ten years, with a yearly sample size of nearly 10 mil. The survey asks simple yes/no questions regarding if the individual (the voter) has ever had either of the two conditions. Are the results of the epidemiology study valid, why/why not, and what can be concluded about the incidence of ARO in the United States from this study? A. Yes, the results are valid. The sample size is sufficient, the study is blinded, and the extensive timeframe of the study minimizes the effect of bias. It can be concluded that the number of new cases of ARO each year did not significantly change across ten years. B. No, the results are not valid. Although the sample size is large, it is affected by non-response bias. The only conclusion that can be drawn is that there were fewer cases of ARO in the United States in 2000 than in 1990 C. No, the results are not valid. Although the sample size is large, it is affected by considerable bias. No conclusions about osteopetrosis can be made. D. Yes, the results are valid. The sample size is large, randomized, and likely to represent the study population as a whole. It can be concluded that there have been no new cases of ARO each year.
C. not valid bc tons of bias, exclude anyone not of voting pop and since congenital disease kids would prob have it. can't say anything abt incidence (new cases in a time period) bc only look at prevalence (ant of pop that have ever had condition)

(In a study conducted on sensation and perception, researchers sought to determine the sensory thresholds of individuals with indifference to pain (IP group) as compared to individuals with normal sensitivity to pain (control group) .

Determine the mean sensory thresholds of Ip and control group individuals for small changes in temperature. B. Determine mean reaction times of IP and control group individuals to changes in pressure that are not temperature related. C. Determine the mean response time to flashes of light in the right and left visual field as a measure of sensory ability. D. Determine mean subjective pain responses of IP and control group individuals to changes in temperature.
Control would want to show that rxn time to other stimuli intact so any diff in perception time are due to diff in sensory threshold and not due to slow rxn times A- experimental condition is already trying to determine sensory threshold B- yes bc then can see if response centers still working w other stimuli and if so then diff in rxn time due to dec receptor sensitivity and not universally slower rxn times C- not tryna eval vision and not refer to diff gps D- not want subjective pain bc not good standard

Increased epigenetic influence on behavior trait within a population would cause measured heritability to: A. Remain constant B. Increase C. Alternate cyclically D. Decrease
D. Epigenetics is how the env affects gene expression thru methylation/acetylation (nongenetic influences on gene expression). So if there is an inc effect of epigenetics then there is more env influence and less genetic, so heritability dec

Suppose the last six nucleotides of a Dh gene segment are 5'G-T-C-G-A-T-3'. A P-addition was made, forming a palindromic sequence on the 3' end. If the original double-stranded DNA was cleaved three nucleotides from the 5' end, what sequence of complementary nucleotides would repair enzymes add to the resulting open strand? (P-addition involves the creation of a DNA hairpin at the ends of gene segments, which causes unpairing of nucleotides to form a single strand. Repair enzymes then add complementary nucleotides, generating a new palindromic sequence.) A. 5'-G-A-T-A-T-C-3' B. 5'-C-T-A-T-A-G-3' C. 5'-C-T-A-A-T-C-3' D. 5'-G-A-T-T-A-G-3'
Only A bc that's the only one that shows a palindrome that would come from a hairpin with one of the cleaved sequences
