Between 1984 and 2003, scientists mapped the human genome, which means they determined the pattern of billions of genes that make a human a human. Originally, it took years to map a single person’s total genome. By 2014 multiple genomes could be mapped in one day. What most likely allowed scientists to start mapping so much faster?

a change to Mendel’s law of dominance
more powerful computer technology
the discovery of how germs work
new scientists repeating gene experiments

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling

If the rna molecule in a human has the nucleotide sequence of guu, this would the amino acid valine would be needed to make the protein. how would this cha process was occurring in a mushroom?
