Document Summary
The eukaryotic genome is made up of double stranded dna (dsdna), as opposed to single stranded dna (ssdna), which is linear (as opposed to the circular dna of prokaryotes). Dna is measures in base pairs, bp, but due to the length of many dna strands, more common notations are kilobase pairs (kbp) which are 1000 base pairs or megabase pairs (mbp) which are. Viruses like hiv have a tiny genome length of 0. 009 mbp. Prokaryotes generally have smaller genomes than eukaryotes, but larger than viruses. The genome size of e. coli is 4. 6 mbp. A yeast genome, one of the smallest eukaryotic genomes, is 12 mbp. Contrary to logic, the tulip genome is enormous, around 33000 mbp and the amoeba dubia genome is even larger, around 660000 mbp. This shows that the complexity of the organism does not directly relate to the genome size.
