Question

dna’s ability to pass on genetic information from one generation to the next is fundamental in ______
the technique based on dna replication that allows amplification of specific dna sequences is called ______
comparative genomics, the study of dna sequences across different species, helps trace ______ relationships and understand how species diverged over time.

Explanation:

First Question:

DNA passing genetic info to next generation is fundamental in heredity (or inheritance). Heredity is the transmission of traits from parents to offspring, and DNA’s replication and transmission enable this.

The technique that amplifies specific DNA sequences using DNA replication is Polymerase Chain Reaction (PCR). PCR uses repeated cycles of heating and cooling to replicate DNA segments, allowing millions of copies of a specific sequence to be made.

Comparative genomics traces evolutionary (or phylogenetic) relationships. By comparing DNA sequences across species, we can determine how closely related they are and infer their evolutionary history, including divergence over time.

Answer:

heredity (or inheritance)
