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

- In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward9.
