- Red numbers are bootstrap scores. Recall that any bootstrap score >= 90% is considered strong. From image attached answer the following: Are most bootstrap scores in your tree >= 90%? Does your tree support the hypothesis that HIV-1 is closely related to chimpanzee SIV (SIV_CPZ)? Does your tree support the hypothesis that HIV-2 is closely related to various non-chimpanzee SIVs?arrow_forwardNote: Dont use guideline answer dont use extra explanation. Just solve full accurate and full accurate ok. With diagrams 1. Describe two methods that are utilized to obtain a high-resolution image of a virus particle structure. And compare the pros and cons of the two methods.arrow_forwardIn the crusade to create a vaccine for Poliomyelitis, Jonas Salk and Albert Sabin created two separate vaccines that proved to be successful in preventing Polio onset. The Salk vaccine, which is given by standard injection, contained virus particles inactivated by an organic solvent. This method has the advantage of inactivating each of the three Polio strains with no bias, Albert Sabin's vaccine, given by oral inoculation via sugar water, contained live virus particles that had been genetically attenuated. With this method, each of the three Polio strains acquired separate mutations that made them unable to infect the human host cells. Strain 2 in particular contained one single nucleotide polymorphism in the internal ribosomal entry site (IRES) that prevented successful viral replication. The organic solvent used to inactivate the Poliovirus in the Salk vaccine significantly alters the viral capsid. For the purposes of this question, let us assume that the capsid proteins are bound…arrow_forward

There are three tools that are fundamental to many areas of biological research: DNA isolation, polymerase chain reaction (PCR) and gel electrophoresis. Write an essay that outlines the key steps in testing for active SARS-CoV-2 (the coronavirus responsible for causing Covid-19) in a patient. Begin with a brief description of how the sample is collected and follow with a description of each of the biotechnology procedures that are used to determine if the patient’s sample contains SARS-CoV-2.arrow_forwardThe table below shows the properties of the genomes of three different viruses. The data were obtained as follows: Nuclease sensitivity was measured by the ability of deoxyribonuclease (DNase) or ribonuclease (RNase) to destroy the genome (a “+" means sensitivity). The ability of the genome to act as mRNA was tested by incubating it in a cell-free system. If amino acids were incorporated into protein, the data are shown as a Finally, the virus particles were tested for the presence of a virion polymerase. If an enzyme was present, the data show whether it could polymerize deoxynucleotide triphosphates (DNTPS) or nucleoside triphosphates (NTPS). "+.
