Genomics

What is genomic sequencing?

• the process of determining the sequence of nucleotides from a single gene or entire genome

• the use of computers and statistical analysis to compare DNA sequences

• the changes in organisms over generations as a result of genomic variations

• the non random increase in the frequency of alleles that increase the chance of survival

what is bioinformatics?

• the use of computers and statistical analysis to compare genomic sequences

• the study of the evolutionary relatedness of organisms

• the sequencing of genomes

• a variety of cultivated crop

what is used in phylogenetics to determine the evolutionary relatedness of organisms?

• fossil evidence

• age of organism

• sequence data

• species of organism

what are the three domains of life?

• bacteria, fungi, prokaryotes

• bacteria, archaea, prokaryotes

• bacteria, archaea, eukaryotes

• bacteria, fungi, eukaryotes

what is assumed when talking about molecular clocks?

• mutation rate is constant

• same species of organism

• same domain of life

• metabolism is constant

what are the most commonly sequenced organisms?

• pest species

• pathogenic organisms

• model organisms

• all of the above

what does the comparison of genomes show?

• many genes are highly conserved across different organisms

• land plants diverged before land animals

• horizontal gene transfer has occurred

• a constant mutation rate

what is used to show the sequence of events in evolution?

• phylogenetics and molecular clocks

• phylogenetics and bioinformatics

• molecular clocks and bioinformatics

• bioinformatics and pharmacogenetics

what is the study of evolutionary history and relationships?

• phylogenetics

• bioinformatics

• pharmacogenetics

• molecular clocks

what diverged first?

• land plants

• land animals

• eukaryotes

• prokaryotes
