The value of using short tandem repeats (STRs) in DNA profiling is that Multiple Choice they signal to researchers where there are genes that can be more easily cloned or grown in stem cells. the tandem repeat sequences are those that can be made into recombinant DNA. the DNA patterns can be used to identify a suspect with a high degree of accuracy. their patterns are not variable.

STRs are short, repeating sequences of DNA that vary in length between individuals. This variability is what makes them useful for DNA profiling. Show more…

Short tandem repeats (STRs) in DNA are often used in forensic analysis and for determining paternity. What characteristic of STRs makes them useful for these practices? Every racial and ethnic group has inherited different short sequence variations in DNA that are repeated in tandem. These sequences are acted upon differently by natural selection in different environments. The sequence of DNA that is repeated varies significantly from individual to individual. The number of repeats is highly variable from person to person or animal to animal.

Which of the following characteristics of short tandem repeat sequences (STRs) in DNA makes them useful for forensic as well as paternity analyses? 1. The DNA sequences within the STRs can vary significantly from individual to individual. 2. The number of repeats at STR loci is the same in everyone. 3. Every racial and ethnic group has inherited different short tandem repeats. 4. The number of repeats is highly variable from person to person.

In order to distinguish the DNA of one person from another, scientists often rely on the presence of short tandem repeats (STRs). These consist of short DNA sequences that are repeated many times in a row. Why are STRs useful for identification
