How is mtdna used to trace lineages quizlet
WebDNA sequencing is the process of determining the sequence of nucleotide bases (As, Ts, Cs, and Gs) in a piece of DNA. Today, with the right equipment and materials, sequencing a short piece of DNA is relatively straightforward. Sequencing an entire genome (all of an organism’s DNA) remains a complex task. It requires breaking the DNA of the ... Web29 sep. 2024 · Because both Y-chromosome DNA and mtDNA are smaller and inherited form only one parent, thus less subject to mutations and changes, they are more useful in tracing lineages through deep time. However, they pale in comparison to the entire nuclear genome in terms of size and available base sequences to analyze. Fast Facts
