1.8 Criteria Flashcards
What is genomic sequencing?
It is the determination of the sequence of nucleotides bases for individual genes and entire genomes.
How is bioinformatics used?
uses computer and analysis to compare sequence sequence data.
What is one of it’s uses?
It can be used to compare genomes from different species by looking for sequences similar to known genes.
What does gene comparison show?
It shows many genes are conserved across different organisms.
What genomes have been sequenced?
includes disease causing and pest species.
What organisms are important for research?
model organisms
What is phylogenetics?
It is the study of evolutionary history and relatedness of different species.
How is the sequence of events in evolution determined?
Through using sequence data and fossil records.
What is a molecular clock?
The changes in nucleotide sequences (sequence divergence) or amino acid sequences.
How are molecular clocks and phylogenetics used?
To determine main events in evolution.
What evidence does the comparison of sequences provide?
It provides evidence of the 3 domains of life. Bacteria, archaea and eukaryotes.
What is the main sequence of events in evolution of life?
- Cells
- last univerasl ancestor
- Prokaryotes
- photosynthetic organisms
- Eukaryotes
- multicellularity
- Animals
- Vertibrates
- Land plants
Why are individuals genomes analysed?
They are analysed to predict the likelihood of developing certain diseases.
What is pharmocogenetics?
The use of genome data in the choice of drugs for treatments.
What is meant by personalised medicine?
The selection of the most effective drugs and dosage based on personal genome sequence data.
