What is DNA typing?

• It is the process of creating numerous strands of DNA fragments from preexistingones using nucleotides

• It is the process of determining what genes code for specific proteins

• It is the process of determining the sequence of an organism

• It is the process of separating an individual’s unique sequence of DNA fragmentsto observe distinct patterns

Why would a forensic scientist use noncoding regions of DNA rather than codingregions of DNA?

• The noncoding regions of DNA are identical to each individual

• The noncoding regions of DNA are unique to each individual

• The noncoding regions of DNA are not used. The coding regions are actuallyused

• The noncoding regions of DNA can create proteins that can be identified.

• gene therapy

• pharmacogenomics

Which of the following sentences best describes single nucleotide polymorphisms(SNPs)?

• SNPs are the study of how genetic inheritance affects the body’s response todrugs

• SNPs are variations in the DNA sequence that occur when one nucleotide in thegenome is altered

• SNPs are fragments created by restriction enzymes and used by scientists.

• SNPs are regions of linked variations in the human genome and are inheritedtogether

The process of using a viral vector to insert a normal gene into a chromosome toreplace a dysfunctional gene is called .
