match the definition with the correct vocabulary.
sequence of dna added to trigger replication of a specific section of dna
portion of a gene that is not expressed.
a method of separating molecules, such as dna, according to size.
dna fragment that restriction enzyme creates, as in preparation for gel electrophoresis.
pattern of dna fragments obtained by analyzing a person’s unique sequences of noncoding dna.

1
electrophoresis
primer
restriction fragment
dna fingerprinting (profile)
intron

Explanation:

Each definition is matched to the corresponding term based on core molecular biology definitions:

1. Primers are short DNA sequences that initiate DNA replication of a target region.
2. Introns are non-expressed, non-coding segments within genes.
3. Electrophoresis separates molecules like DNA by their size via gel matrix.
4. Restriction fragments are DNA pieces cut by restriction enzymes for electrophoresis.
5. DNA fingerprinting uses unique non-coding DNA fragment patterns for identification.

Answer:

1. sequence of DNA added to trigger replication of a specific section of DNA → Primer
2. portion of a gene that is not expressed → intron
3. a method of separating molecules, such as DNA, according to size → Electrophoresis
4. DNA fragment that restriction enzyme creates, as in preparation for gel electrophoresis → Restriction fragment
5. pattern of DNA fragments obtained by analyzing a person's unique sequences of noncoding DNA → DNA fingerprinting (profile)
