genome projects Flashcards
define genome
complete map of all the genetic material in an organism
what is bioinformatics
science of collecting and analysing complex biological data (e.g: genetic codes)
uses computers to read, store, organise biological data at a faster rate. uses algorithms to analyse and interpret biological data
what does WGS stand for
Whole - Genome Shotgun
what happens during the process of WGS
researchers cut DNA into small easily sequenced fragments and using computer algorithms align overlapping segments to assemble the entire genome
what do SNPs stand for
Single Nucleotide Polymorphisms
how many SNP’s do humans have
1.4 million
define SNP
single base variations in the genome that are associated with a disease and other disorders
medical screening has allowed quick identification of medical problems and early intervention to treat them
define proteome
all the proteins produced by a cell
these proteins are only produced when a gene is switched on
(all the proteins produced by any given cell or organism at any given time under specific conditions)
give 2 reasons why determining the genome of prokaryotic organisms is relatively easy
- most prokaryotes have one circular piece of DNA
(not associated with histones) - no introns
what are prokaryotes used to do in the human genome
to identify antigens so vaccines can be developed
why is it hard to determine human genome
- DNA has introns
- DNA is different for everyone
- hard to translate knowledge of genome into proteome
