Concept introduction:
Viruses differ considerably in their genomes. Some viruses have genomes composed of RNA, while others have genome made up of DNA. In addition to this, the genome can be either single stranded or double stranded. Since viruses have evolved independently therefore, it is very difficult to classify them on the basis of evolutionary relatedness. They are generally classified on the basis of the type of
Explanation of Solution
The steps necessary to synthesize
1. The first step involves the melting of double stranded DNA to allow the binding of DNA dependent RNA polymerase enzyme.
2. The second step involves the synthesis of
The steps necessary to synthesize
1. Replication of single stranded (+) DNA to form double stranded DNA.
2. The double stranded DNA then act as template for the synthesis of
The steps necessary to synthesize
1. Replication of single stranded (-) DNA occurs to form double stranded DNA.
2. The double stranded DNA then act as template for the synthesis of
The steps necessary to synthesize
1. The single stranded (+) RNA is converted into single stranded (-) DNA with the help of enzyme called reverse transcriptase, a RNA dependent DNA polymerase.
2. The single stranded (-) DNA is then replicated to form double stranded DNA, which is then used as template by the DNA dependent RNA polymerase to synthesize
3. In some single stranded (+) RNA, the positive sense RNA is first converted into negative sense RNA which is then used as template by RNA dependent RNA polymerase to synthesize
The steps necessary to synthesize
1. The single stranded (-) RNA is used as template to synthesize positive sense
2. The

- An 1100 pound equine patient was given 20 mg/kg sucralfate 3 times a day, 2.8 mg/kg famotidine twice a day, and 10mg/kg doxycycline twice a day. Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?arrow_forwardThe patient needs a solution of 2.5% dextrose in Lactated Ringer’s solution to run at 75 ml/hr for at least the next 12hours. LRS comes in fluid bags of 500 ml, 1 Liter, 3 Liters and 5 Liters. How can a 2.5% solution be made by adding50% dextrose to the LRS?arrow_forward“Gretchen” was a 68-pound canine who came to the VMTH as small animal surgery patient. She receivedacepromazine, 0.2 mg/kg from a 10 mg/ml solution and oxymorphone, 0.08 mg/kg from a 1 mg/ml solution before surgery.What are the mechanisms of action of acepromazine and oxymorphone? Why would they be given together?How many mg provide each dose and how many ml of each of these solutions were given?arrow_forward

However, a SNP in the position shown in gray (right) would prevent cleavage at this site by EcoRI One of the SNPs in B. rapa is found within the Park14 locus and can be detected by RFLP analysis. The CT polymorphism is found in the intron of the Bra013780 gene found on Chromosome 1. The Park14 allele with the "C" in the SNP has two EcoRI sites and thus is cleaved twice by EcoRI If there is a "T" in that SNP, one of the EcoRI sites is altered, so the Park14 allele with the T in the SNP has only one EcoRI site (Fig. 5-3).

When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer.
