The "molecular clock" of the rate of change in a segment of DNA during evolution depends on which of the following? (select all that apply) • A process called purifying selection • Whether that DNA contains functionally important sequences • Whether the DNA can be easily sequenced • The structure of the RNA molecule produced from that DNA The rate that mutations occur in that species or type of DNA Message @ProBot ✨

DNA from actively dividing bacteria was isolated and examined to find two groups of DNA.  One group DNA included very large molecules (thousands or even millions of nucleotides long), and the other included short stretches of DNA (several hundred to a few thousand nucleotides in length). What was the researcher actually seeing in these two groups? Group of answer choices mRNA molecules and siRNA molecules Okazaki fragments and RNA primers leading strands and Okazaki fragments leading strands and RNA primers

7 of 15 From the list below identify the most suitable software used to visualize a change in amino acid on a protein structure: O Jalview, O Uniprot Database. O Ensembl Neanderthal genome. O NCBI database. O Ensembl Human Gr38. OPDB database. OBLAST. O Ancient Genome Browser. O Ensembl Human Gr37. O SNPdb database of human mutations. O Chimera.

You're the geneticist on a team that's uncovered a Wooly Mammoth in the ice and you want to study the function of its hemoglobin protein. First, you need to PCR amplify the gene to be able to Sanger sequence it. What reference genome do you use to design primers? O The human genome because it's the best O The bat genome because bats are cool O The elephant genome because it likely has the most sequence similarity given evolutionary distance O The E. coli genome because they're such a great model organism O The yeast genome because they're small and they're a eukaryote
