Document Summary
Approximately 65% if neanderthal genome obtained from ancient dna samples from fossils. Approximately 1-4% od dna from anatomically modern europeans and asians may have originated from. Much of this neanderthal-derived dna is related to immune function. Some people suggest that some allergies we experience is related to our neanderthal dna. Dna sequences could have been subject to contamination through time. A bacteriophage is a virus that infects bacteria cells. The phage itself has a very small genome, its about. 10-50 kilolabse, 1 kilobase is 1000 base pairs. Plasmids are very small circuluar pieces of dna, and they can replicate separately from when the big dna replicates. Antibiotic resistance genes are usully on plasid chromosomes. These circles are mapping where no mutation genes are that can cause disease. The micothondria genome is small because many of the genes that used to be there are now in the nucleus.
