genomic sequencing 1.8 Flashcards
what happens in genomic sequencing
the sequence of nucleotide bases can be determined for an induviduals gene or genomes
to compare sequence data what is required
bioformatics
what are bioformatics
computer and stadistical data
genomes can be sequenced for research of
disease causing organisms
pest species
model organisms
what is phylogenetics
the study of evolutionary history and relationships
the sequence of events has been determined by
sequence data
fossil evidence
molecular clocks
phylogenetics
what is sequence daylta used to study
evolutionary relatedness of species
whats sequence divergence used for
to estimate time since lineages diverged
name the three domains of life
archeria
bacteria
eukaryotes
sequence data and dossil evidence has been used to determine the main sequence of events in evolution of life: name these sequences
last universal ancestor photosynthetic organisms prokaryotes eukaryotes multicelullar organisms animals vertibrates land plants
what are molecular clocks used for
to show when a species diverged in evolution
what do molecular clocks assume
constant mutation rates
what do molecular clocks show
differences in dna sequences and amino acid sequences
differences in sequence data between species indicate what
the time of divergence from a common ancestor
an individuals genes can be analised to indicate what
the likelihood of developing certain diseases
