Topic 5 (level C) Flashcards
What do systematics do?
Systematics compares human genome sequence data and genomes of other species to provide information on evolutionary relationships and origins
What do systematics provide information on ?
Evolutionary relationships and origins
What is personalised medicine based on ?
Personalised medicine is based on an individual’s genome
What may the analysis of an individual’s genome lead to ?
Analysis of an individual’s genome Mays lead to Personalised medicine through understanding the genetic component of risk of disease
Personalised medicine may be made through what ?
Through understanding the genetic component of risk of disease
What does PCR mean ?
Polymerase chain reaction
What is PCR?
PCR is the amplification of dna using complementary primers for specific target sequences
What’s the first stage of PCR ?
The first stage of PCR is where the dna is heated to separate strands then cooked for primer binding
What’s the second stage of PCR
The second stage of PCR Is heat tolerant DNA polymerase then replicates the region of DNA
Final stage of PCR
The final stage of PCR is repeated cycles of heating and cooling amplify this region of DNA
What is used to detect the presence of specific sequences in samples of DNA ?
Arrays of DNA probes
Arrays of DNA probes are used to detect what ?
Arrays of DNA probes are used to detect the presence of specific sequences in samples of DNA
What’s the description of probes ?
The probes are short single stranded fragments of DNA that are complementary to a specific sequence
What does fluorescent labelling allow ?
Fluorescent labelling allows detection
Applications of DNA profiling allow what ?
Applications of DNA profiling allow the identification of individual’s through comparison of regions of the genome with high variable numbers of repetitive DNA sequencing
