The TPOX locus is one of the genetic loci used for forensic analysis of DNA. The TPOX locus has the repeat structure [TAGA]n. What type of molecular marker is TPOX? a copy number variant a simple tandem repeat a single nucleotide polymorphism

Restriction endonucleases are bacterial enzymes that cleave duplex (double-stranded) DNA at specific nucleotide sequences. The mode of replication of the animal virus SV40 has been investigated by using restriction endonucleases that cleave SV40 DNA into a number of unique segments. Like most viruses, SV40 DNA is circular. The map positions of the 11 fragments produced by a pair of restriction endonucleases are shown on the next page. Immediately following a 5 or 10 minute pulse of radioactively labeled thymidine, labeled SV40 molecules that have completed replication during the pulse are isolated. These newly replicated DNA molecules are digested by the restriction endonucleases and the resulting fragments are analyzed for the relative amounts of pulse label they contain. The results are in the table below. Assume that at the time the label was added there was a random population of replicating SV40 DNA molecules in all possible stages of synthesis. From the information given below,…

If the researchers carry out a PCR for this gene from the CD8+ T cells, what result would you expect?Explain.

#2.) Mary wants to further confirm if she is a carrier for this lethal gene. She was told that a new SNP marker was identified RFPL marker. She requested to do SNP test for all the DNA samples. The results are: her parents are heterozygous for SNPs (that is to say, one chromosome is wild-type and another one contains the SNP). The sister who passed away is homozygous for the SNP. Mary does not have this SNP. So now what is the probability of Mary as a carrier of the death gene?

when various strains of lambda phage are seeded on a lawn of e.coli, they can form clear or turbid plaques. Explain the difference between the two types of plaques. can all bacteriophage form clear and turbid plaques?
