A2 Biology (OCR)- Sequencing the genome of an organism

HideShow resource information

Sequencing can only work on DNA lengths of about 750 pairs, which means chromomes must be broken up into sections. Sequencing is carried out a number of times on overlapping fragments, to increase accuracy.

1) Genomes are mapped to identify where they have come from. Info that is already known is used- for example, the location of microsatellites (runs of repetitive sequences of 3-4 base pairs found in the genome).

2) Samples  of the genome are…
