Forensics DNA Fingerprinting

Front

What are STRs (Short Tandem Repeats)?

Back

Tandem repeats of short DNA sequences with varying numbers of repeats found among individuals, used in DNA profiling.

Front

What charge does the anode carry in gel electrophoresis?

Back

Positive charge.

Front

What is a DNA Fingerprint?

Back

A collection of DNA fragments that can be used to identify genetically unique individuals.

Front

What does a DNA Fingerprint represent?

Back

The pattern of DNA fragments obtained by examining a person's unique sequence of DNA pairs.

Front

What is the complementary DNA sequence for ATG TGA CAG?

Back

TAC ACT GTC.

Front

What is PCR (Polymerase Chain Reaction)?

Back

A technique used to amplify small segments of DNA, making millions of copies of a specific DNA sequence.

Front

What is gel electrophoresis used for?

Back

A method for separating DNA fragments based on their size, allowing for analysis and comparison.

Front

What are VNTRs (Variable Number Tandem Repeats)?

Back

Repeats of a DNA sequence that vary in number among individuals, used in genetic profiling.

Front

What is the role of DNA polymerase in DNA replication?

Back

An enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of alleles in genetics?

Back

Different versions of a gene that can result in variations in traits among individuals.
