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

• DNA Fingerprint

• Allele

• Chromosome

Answer explanation

A DNA fingerprint is a unique pattern of DNA fragments that identifies an individual based on their specific DNA sequence. This distinguishes it from alleles and chromosomes, which are broader genetic concepts.

A molecule that cuts a DNA molecule at a specific, base sequence.

• Allele

• Restriction Enzyme

• DNA Probe

Answer explanation

A restriction enzyme is a protein that cuts DNA at specific sequences, making it essential for genetic engineering and molecular biology. Alleles are variants of genes, and DNA probes are used to detect specific sequences, not cut them.

DNA fingerprinting works because

• Most genes are dominant

• All organisms contain RNA

• The most important genes are different among most people

• No two people, except identical twins, have exactly the same DNA 

Answer explanation

DNA fingerprinting relies on the fact that no two individuals, except identical twins, have identical DNA. This uniqueness allows for accurate identification and comparison of genetic material among different people.

A cell structure that contains genetic information along strands of DNA.

• Allele

• Chromosome

• DNA
