DNA Evidence (Forensics)

Front

What is the backbone of DNA made up of?

Back

The backbone of DNA is made up of phosphate and deoxyribose.

Front

In which year was DNA evidence first used to get a conviction at trial?

Back

DNA evidence was first used to get a conviction at trial in 1987.

Front

What type of evidence is DNA classified as?

Back

DNA is classified as Individual evidence.

Front

In gel electrophoresis, where will the largest DNA fragment appear?

Back

The largest DNA fragment will appear closest to the starting wells.

Front

What part of the nucleotide is bound to sugar to form the middle of the DNA molecule?

Back

The nitrogen bases are bound to sugar to form the middle of the DNA molecule.

Front

What are the four nitrogen bases found in DNA?

Back

The four nitrogen bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the double helix structure of DNA?

Back

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

Front

What is the function of the phosphate group in DNA?

Back

The phosphate group forms the backbone of the DNA molecule and links the sugar molecules together.

Front

How does gel electrophoresis separate DNA fragments?

Back

Gel electrophoresis separates DNA fragments based on their size, with smaller fragments moving faster through the gel than larger ones.
