genome projects Flashcards
what are sequencing projects
to map the dna base sequence that make up the genes of an organism and map these genes on the individual chromosomes
how do we sequence 20000 genes
we use bioinformatics
what is bioinformatics
it is the science of collecting and analysing complex biological data such as genetic codes
what does it use
computers to read store and organise biological data at a much faster rate and also uses algorithims
what technique do we use to complete the dna base sequence of an organism
whole genome shot gun sequencing
what does this involve
rresearcher cutting dna into small easily sequenced sectionsand then use computer algoritihim
what do these algorithims do
thy allign overlapping segments to assemble the entire genome snd are constantly updated
what medical advances have been made
medical screening to identify certain diseases by identifying snps in the genetic code
what are saps
single based variations in the genome that are associated with disease and other disorders
what does medical screening allow
quick identification of individuals that have potential to develop a medical disorder and allow early intervention
what is greater importance to human knowledge
not the genes but the nature of the protiens that the genes code for
what are these protiens called
the proteome
what is proteome
all the protiens produced by a genome at a given time under specified conditions
why is sequencing dna in bacteria useful
it can help us identify genes that can be exploited and be used in toxic envirometns for cleaning pollutants
why is determining proteome of bacteria easy
the prokaryotes only have one circular piece of dna that is not associated with histones
and there is no non coding portions of dna
