What is Borrelia burgdorferi?

300

This term refers to the overall process by which eukaryotic cells evolved.

What is eukaryogenesis?

300

This value needs to be greater than 1% for an allele to be considered a SNP.

What is the minor allele frequency? 

300

Possession of this gene distinguishes an ERV from a LINE.

What are London and Denmark? 

400

The bacterial lineage that shares the greatest sequence similarity to mtDNA.


What are alpha-proteobacteria?

400

This theory proposes that it was an archaean cell and not an early eukaryotic cell that engulfed the bacteria that become the mitochondria.

What is the mitochondria early theory?

400

This term represents the frequency of a heterozygous genotype.

What is 2pq?

400

These two regions of a retrovirus genome flank the coding region and are identical at the time of insertion into the host genome.

What are long terminal repeats (LTRs)?

400

Ancient DNA samples often have G to A and C to T mutations near the ends of fragments due to this process.


What is cytosine deamination?

500

Phylogenetic analysis of this mitochondrial gene proved that molecular sequences could be used to infer evolutionary relationships among diverse species.
