What is the DNA fingerprint pattern of a child in relation to their parents?

Back

The DNA fingerprint pattern of a child is 50% similar to the father and the rest similar to the mother.

Front

What technique is used to separate different sized DNA fragments?

Back

Gel Electrophoresis is used to separate different sized DNA fragments.

Front

How can DNA profiles help in identifying babies in case of a mix-up?

Back

DNA profiles can determine which baby belongs to which set of parents based on the genetic similarities.

Front

What are the base pairing rules in DNA?

Back

A pairs with T; and C pairs with G.

Front

What is the role of restriction enzymes in DNA analysis?

Back

Restriction enzymes cut DNA at specific sequences, allowing for the analysis of DNA fragments.

Front

What is the significance of DNA profiling in forensic science?

Back

DNA profiling is used to identify individuals based on their unique DNA patterns, aiding in criminal investigations.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of nucleotides, which include a sugar, phosphate group, and nitrogenous base.

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of gel electrophoresis in DNA analysis?

Back

Gel electrophoresis separates DNA fragments based on size, allowing for analysis and comparison.
