Question

DNA markers can serve as a proxy for the genome and hence can be used in the identification of any organism or individual organism including humans. Highly repetitive sequences of DNA called STRs:_______.

Answer 1

Answer:

Highly repetive sequences of DNA called STRs:

STR analysis is a tool in forensic analysis that can be used STR for

human identification, paternity analysis and genetic mapping.

STR loci consist of short, repetitive sequence elements of 3 to 7

bases pairs in length, and may be amplified using the

polymerase chain reaction (PCR).

Explanation:

S hort T andem R epeat (STR) analysis is a common molecular biology

method used to compare allele repeats at specific loci in DNA

between two or more samples. A short tandem repeat is a

microsatellite with repeat units that are 2 to 7 base pairs in length,

with the number of repeats varying among individuals, making STRs

effective for human identification purposes. [1] This method differs

from restriction fragment length polymorphism analysis (RFLP) since

STR analysis does not cut the DNA with restriction enzymes.

Instead, polymerase chain reaction (PCR) is employed to discover

the lengths of the short tandem repeats based on the length of the

PCR product.

Answer 2

Answer:

DNA markers can serve as a proxy for the genome and hence can be used in the identification of any organism or individual organism including humans. Highly repetitive sequences of DNA called STRs:can be used in DNA fingerprinting for forensic purposes

Explanation:

Short Tandem repeats (STRs) consist of short sequences of neucleotides that are repeated many times tandemly.

STR analysis is a technique for producing and comparing DNA fingerprints that reflect the lengths of STR sequences at specific sites in the genome hence can be used in DNA fingerprinting for forensic purposes

It has been extremely successflu for use in personal identification of criminal suspects, paternity issues, as well as indentification of diseases.
