What is the term for the pattern of DNA bands created from the process of gel electrophoresis?

Back

DNA Fingerprint

Front

Are the elephants homozygous or heterozygous for the gene shown from marker B?

Back

One is heterozygous and one is homozygous.

Front

What lab technique is used to amplify DNA sequences to produce billions of copies of a fragment of DNA?

Back

Polymerase Chain Reaction (PCR)

Front

What is the region of DNA on either side of a sequence of interest, such as an STR or gene?

Back

Flanking Sequence

Front

Are the elephants homozygous or heterozygous for the gene shown from marker C?

Back

Both are heterozygous.

Front

What is the purpose of gel electrophoresis in DNA analysis?

Back

To separate DNA fragments based on size.

Front

Define Short Tandem Repeats (STR).

Back

Short, repeated sequences of DNA that are used in genetic profiling.

Front

What is the significance of a DNA fingerprint in wildlife forensics?

Back

It helps identify individual animals and determine genetic relationships.

Front

Explain the role of PCR in forensic science.

Back

PCR allows scientists to create millions of copies of a specific DNA segment for analysis.

Front

What does it mean for an organism to be homozygous for a gene?

Back

It has two identical alleles for that gene.
