DNA review

Front

What is the primary function of DNA?

Back

The primary function of DNA is to store and transmit genetic information.

Front

What does STR stand for in DNA analysis?

Back

STR stands for Short Tandem Repeat, which are repeating sequences in DNA used for genetic profiling.

Front

What type of evidence is DNA from the nucleus considered?

Back

DNA from the nucleus is considered individual evidence.

Front

Which loci in STR analysis is homozygous?

Back

In the provided example, the homozygous loci is vWA.

Front

What is DNA Fingerprinting?

Back

DNA Fingerprinting is the pattern of DNA fragments obtained by examining a person's unique sequence of DNA base pairs.

Front

What is the role of PCR in DNA analysis?

Back

PCR (Polymerase Chain Reaction) is used to amplify small segments of DNA, making it easier to analyze.

Front

What is the significance of the D2S1338 locus in STR analysis?

Back

D2S1338 is significant because it has the most base pairs among the loci analyzed.

Front

What is the difference between class evidence and individual evidence?

Back

Class evidence can be associated with a group, while individual evidence can be linked to a single source.

Front

What is electrophoresis used for in DNA analysis?

Back

Electrophoresis is used to separate DNA fragments based on their size.

Front

How does DNA structure relate to its function?

Back

The double helix structure of DNA allows for the storage of genetic information and its replication.
