Select True or False for each statement below. 1) Both PCR and droplet digital PCR (ddPCR) use a droplet generator. [Fasle1] 2) ddPCR involves partitioning the sample so that PCR is done on a single DNA molecule (on average) whereas PCR uses a sample with many DNA molecules. [True2] 3) ddPCR uses primers and PCR does not use primers. [False2]

Fill in the blanks with the best answer from the dropdown menu. Use each item from the dropdown menu only once.     In the immune system, the complement cascade tags [pathogens] for [phagocytosis] by [immunecells]. In the brain, the complement system tags [synapses] for [pruning] by [microglia].

Fill in the blanks with the best answer from the dropdown menu.    In GWAS, [SNPallelefrequency] is compared between a control group and an experimental group. A p-value is calculated for each comparison. For each comparison, this p-value tells you the probability that the difference observed between the groups is due to [chance]. 

The same haplotype block on six different homologous chromosomes from the population is shown below. The five SNPs in this block are genotyped on each chromosome; the rest of the DNA sequence (…..) is identical between the chromosomes.   1) How many different haplotypes can you see? [number] 2) Which combination of SNPs could be used as TAG-SNPs to identify the haplotype found in in this haplotype block? [TAGSNPS]

What is the genetic variation in the Huntingtin gene that effects disease risk and disease severity in Huntington’s disease?

Which characteristic distinguishes Huntington’s Disease from other diseases?

Only extrinsic (coming from the outside) Calcium ion will be used for the contractile heart cell’s Action Potential.

Calculate Mean Arterial Pressure from a diastolic pressure of 121 mm Hg and a systolic pressure of 208 mm Hg:

Which part of the intrinsic conduction system delays the impulse briefly before it moves on to the ventricles (HINT–it also can act as a secondary pacemaker of the heart)?
