DNA Profiling Review

Front

What is an electropherogram?

Back

An electropherogram is a graphical representation of the results of a DNA analysis, showing the different DNA fragments separated by size during electrophoresis.

Front

What is DNA phenotyping?

Back

DNA phenotyping is the process of predicting physical appearance and ancestry from an individual's DNA.

Front

What are introns?

Back

Introns are non-coding regions of DNA that do not code for proteins and make up a significant portion of the genome.

Front

From which sources can DNA be recovered?

Back

DNA can be recovered from various sources including saliva, skin cells, and semen.

Front

What is the genotype at the location D18S51?

Back

The genotype at the location D18S51 can be represented as 14,15.

Front

What is the purpose of PCR in DNA profiling?

Back

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

Front

What is CODIS?

Back

CODIS (Combined DNA Index System) is a database that stores DNA profiles for use in criminal investigations.

Front

What is the role of electrophoresis in DNA analysis?

Back

Electrophoresis is a technique used to separate DNA fragments based on their size, allowing for analysis and comparison.

Front

What is genetic genealogy?

Back

Genetic genealogy is the use of DNA testing in combination with traditional genealogical methods to establish family relationships.

Front

What are exons?

Back

Exons are coding regions of DNA that are transcribed into mRNA and translated into proteins.
