Why is a human Rab protein with no direct yeast equivalent chosen as an “outgroup” for a study?

Briefly describe paramutation at the Kit locus in mice. What evidence suggests that small RNA molecules play a role in this phenomenon?

Which of the following patterns was observed, in the experiments of Hershey and Chase, using the T2 bacteriophage of E. coli? radioactive proteins were passed on to viral progeny, but not radioactive polynucleotides radioactive polynucleotides were passed on to viral progeny, but not radioactive proteins both radioactive proteins and radioactive polynucleotides were passed on to viral progeny both radioactive polynucleotides and radioactive proteins were passed on to viral progeny neither radioactive proteins nor radioactive polynucleotides were passed on to viral progeny

what does the Depletion of essential gene products causes spontaneous DNA damage major result mean in this experiment? (interpretation)

In the Human Genome Project, researchers have collectedlinkage data from many crosses in which the male washeterozygous for molecular markers and many crosses wherethe female was heterozygous for the markers. The distancebetween the same two markers, computed in map units, isdifferent between males and females. In other words, thelinkage maps for human males and females are not the same.Propose an explanation for this discrepancy. Do you think thesizes of chromosomes (excluding the Y chromosome) in humanmales and females are different? How could physical mappingresolve this discrepancy?

Using a laser beam, you isolated several R bands from human chromosomes. Answer the following questions What kinds of genes are present in R bands? Which isochors do you expect to be present in the R band? What class of interspersed repeats will be present in R bands? What class of tandem repeats do you expect to find in RG bands? Would you expect to find telomere sequences in some R bands?

Section 1: Create a flow chart image showing the map of the electrical activity of the heart (begin with the SA node) Include each step the electrical activity travels as it goes through the heart. Section 2: Create a flow chart image showing the map of how blood flows through the heart  Include each step starting in the right atria Include the names of valves that the blood passes through   Section 3: Application Describe what is occurring in the heart (regarding contraction) during each step of the electrical activity.  In other words, what does the electrical activity indicate is happening in the heart (atria contraction, ventricle contraction/relaxation, etc). Also, explain how these contractions lead to proper blood flow sending blood to the appropriate areas for oxygen delivery. This section should be no more than one page in length (double spaced for APA format) and should give detailed information about how these three aspects of the heart (electrical activity,…

Which one of the following options most accurately describes how the ~3000 megabases (Mb; ~3,000,000,000 nucleotides) of the haploid human genome are distributed on chromosomes? The haploid human genome is distributed on autosomes 1-22 and X and Y (so, 24 chromosomes). The haploid human genome is distributed on the homologous pairs of autosomes 1-22 and X and Y (so, 46 chromosomes). The haploid human genome is distributed on a single chromosome (so, 1 chromosome). The haploid human genome is distributed on one pair of homologous chromosomes (so, 2 chromosomes).
