Homework Answers
Answer: c. Repeat unit length
STR stands for Short Tandem Repeats. For example, take AGACAGACAGACAGACAGACAGACAGAC. Here, the unit AGAC is the repeating unit that is present in tandem. The length of this repeat unit is the number of nucleotides present in it. Here, AGAC has 4 nucleotides. So, repeat unit length is 4.
Core repeat sequence refers to the sequence of the repeat unit rather than the length.
There exists no terminology as Star STR in the genetic literature.
Population match probability involves the measurement of the probability of a genetically unrelated person who has been selected randomly from a population followed by the process of genotype matching that is found out of the evidence. It is not related to the number of nucleotides in the repeat sequence of STR.

using c language String Challenge Have the function StringChallenge(str) read str which will contain two strings separated by a space. The first string will consist of the following sets of characters: +, *, $, and {N} which is optional. The plus (+) character represents a single alphabetic character, the ($) character represents a number between 1-9, and the asterisk (*) represents a sequence of the same character of length 3 unless it is followed by {N} which represents how many...

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...
