Document Summary
Genome: a set of genetic instructions within a biological compartment. Genomic size: is the length of one set of those instructions. On the left, there are 6 chromosomes and they"re all identical. On the right, there are 6 chromosomes but they"re all different from one another. You"d sum the measurement of all six chromosomes. You can look at genomes in terms of their length using these various units. Its is a chemical molecule so you can also talk about this in terms of mass. The mass is small and measured in pico grams. One pico gram = 1 billion base pairs (1gb) Drawback: not good if your genome is big. There are lots of repeats that confuse the genome. Someitmes there"s too much data for the computer to even process. Sequencing doesn"t allow you to see the final product first (puzzles) so you are unaware that you are missing chuncks.
