WHICH ONE is the difference between VNTRs (Variable Number Tandem Repeats) and STRs (Short Tandem Repeats) used in forensic DNA analysis?
a) VNTRs technology allows trace DNA to be analyzed; STRs technology does not.
b) VNTRs can be amplified by PCR; STRs cannot be amplified by PCR.
c) VNTRs cannot be multiplied to obtain an allele frequency; STRs can be multiplied to obtain an allele frequency.
d) VNTRs polymorphic DNA sequence is much longer than that of STRs.
Homework Answers
VNTR are the type of minisatellite DNA that are 10-60 base pair long while STR are the type of microsatellite DNA and are 2-6 base pair long. So VNTR DNA sequence is much longer than that if STRs.
Both can be multiplied and amplified by using PCR
Option D is correct

Most of our DNA sequence is identical, however there are places in the genome quence can vary from person to person. These variations are where thee sts use one type of highly variable polymorphisms for DNA analysis. STRs (short called polymorphisms.

In 1994, Congress passed the DNA Identification Act which authorized the FBI to do 2 things: (1) create and maintain a national DNA database, and (2) establish standards for forensic DNA testing. Because the human genome is full of DNA tandem repeats and because they vary in the number of contiguous repeat units, it was decided to use tandem repeats to build the DNA database. In 1996, 13 loci were chosen to be the core short tandem repeats (STR) for...

When there is a match between a forensic DNA sample collected
at a crime scene and DNA subpoenaed from a suspect, the genotype
frequency can be interpreted in two ways. In one sense, it is the
probability of finding that specific genotype in the population. In
another sense it is the probability that the match is due to
chance.
How does the results from the most common alleles in
the different populations affect the application of using these
results for...

Which of the following is TRUE of incomplete penetrance? Select one: a. Epistatic interactions can result in incomplete penetrance in some cases. b. Environmental factors do not influence penetrance. c. Incomplete penetrance implies that some individuals will experience less severe forms of disease, such as cancer or Alzheimer's. d. Incomplete penetrance is never observed with Huntington's disease e. Incomplete penetrance refers to cases in which individuals developing a particular disease (e.g., cancer or Alzheimer's) lack the typical genotype for this...

diabetes in this article
Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
