After the genomes of multiple Homo neanderthalensis individuals were sequenced, it became clear that this species diverged from the Homo sapiens lineage about 540,000 years ago. The two species evolved separately until about 40,000 years ago when they encountered one another again in the region that would become Europe. The Neantherthals became extinct around 30,000 years ago. Please answer the following questions about genomes and genes for these species. 2A. The single nucleotide mutation rate in both species is about 1 per 109 base pair per year. With a genome size of 3 billion base pairs, how many fixed single nucleotide differences would you expect to see between the two genomes when the two species first encountered each other? Explain your calculations. 2B. In the genomes of modern Europeans, remnants of the Neanderthal genome now can be identified (i.e. many Neanderthal- specific mutations can be seen in the human genomes). How can we be sure this is "Neanderthal DNA" in the human genome and not just a bunch of mutations that occurred independently at different times in the human lineage? 2C. Why are there no remnants of the Neandertal Y-chromosome in the modern human population?
calculate the dilutionsneeded to create antibiotic solutions at 10x the desiredfinal concentrations for this experiment?
You were so intrigued that you wanted to re-do the experiment at home to show your mom how evidence of chromosomal cross-overs can be seen in an ascus!You go to a nearby magical forest and just by luck come across anascoma. You crush it on a slide..
The baroreceptors are responsible for detecting and responding to changes in mean arterial pressure. Please describe the responses of baroreceptor reflex to both an acute and a chronic increase in mean arterial pressure.
Outline how to use the Process Evaluation method to increase the knowledge of signs and symptoms of stroke for stroke prevention for seniors living independently with emphasis on seniors in Punta Gunda
When is DNA replication important, when does it occurs, whatbuilding blocks and enzymes are necessary for this process toproceed? What is the role of DNA polymerase in the process of DNAreplication?
In the dihybrid cross shown below, genes A and B are linked with 10map units between them. A is completely dominant to a, and B is completely dominant to b, the phenotypic ratio
Describe the activation-inhibition crosstalk principle between skin tissues in the formation of new hair and the development of psoriasis.
What happens to the electrons carried by NADH and FADH2?
A 20.0 mL sample of gastric juice was taken from a patient suspected of having hypochloridia (low stomach acid). The sample was taken several hours after a meal so there was no ingested food or drink, and it was assumed no buffers were present.
Use the momentum balance method and derive the flow rate of a Newtonian fluid flowing across a cylindrical tube driven under pressure of rate change if the tube diameter decreases by half?
The presence of blood and protein in the urine can indicate the inflammation of the glomerulus. Why would glomerular inflammation result in these substances passing into filtrate and the urine?
In the wild, male house finches (Carpodus mexicanus) vary considerably in the amount of red pigmentation in their head and throat feathers, with colors ranging from pale yellow to bright red.
