g The sequencing of entire genomes has made it possible to examine the level of gene expression in a particular cell or tissue by using oligonucleotide probes to assess the level of mRNA from a particular gene. This is done most effectively through the use of: Southern blotting. screening of genome libraries. gene disruption or knockout. DNA microarrays. RNA interference.

lesson summarykaryotypes a genome is the full set of all the genetic information that an organism carries in its dna. chromosomes arebundles of dna and protein found in the nucleus of a eukaryotic cell.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
