What does it mean for an individual to be homozygous at a locus?

Back

It means the individual has two identical alleles at that locus.

What is the role of DNA polymerase in PCR?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides to the template strand.

Front

What is the function of primers in PCR?

Back

Primers are short sequences of nucleotides that provide a starting point for DNA synthesis.

Front

What is the difference between homozygous and heterozygous alleles?

Back

Homozygous alleles are identical, while heterozygous alleles are different.

Front

What is the purpose of gel electrophoresis in DNA analysis?

Back

Gel electrophoresis separates DNA fragments based on their size.
