Lesson 3 - Identifying individual species Flashcards
meaning DNA sequencing
the process by which the base sequences of all or part of the genome of an organism is worked out
meaning DNA profiling
the process by which the non-coding areas of DNA are analysed to identify patterns
meaning bioinformatics
the development of the software and computing tools needed to organise and analyse raw biological data that help us to make sense of the large quantities of data being generated
why is it difficult to identify species from their phenotype
because external conditions can result in major differences in appearance of individuals of the same species
meaning DNA barcoding
the analysing of short genetic sequences from a part of the genome common to a particular group of organisms e.g. regions in the mitochondria for animals and regions in the chloroplast in plants
why are the regions in the mitochondria in plants not used for DNA barcoding
because the mitochondria evolves too slowly
