The acellular organism is defined as the organism that is not made up of the cells, but still has nucleic acid , and has the ability to replicate within the host cell genome. As acellular organisms do not have a cell so they are not considered as an organism. So, it is better to call them a particle rather than an organism.

The acellular organism is defined as the organism that is not made up of the cells, but still has nucleic acid, and has the ability to replicate within the host cell genome. As acellular organisms do not have a cell so they are not considered as an organism. So, it is better to call them a particle rather than an organism.

Expert Solution & Answer

Answer to Problem 1Q

Correct answer:

Viruses are the acellular microorganisms lacking a nucleus. Therefore, option (d) is correct.

Option (d) is given as “virus”.

Explanation of Solution

Justify the reasons for the correct statement:

Viruses are the acellular entities that are considered as ultramicroscopic infectious particles, viruses are known to infect all the life forms present or earth, from microbes to plants and animals. Viruses have either DNA or RNA as their genetic materials yet they lack cell organelles. Hence, they are named as acellular organisms.

Hence, option (d) is correct.

Justify the reasons for the incorrect statements:

Option (a) is given as “bacterium”.

Bacteria have a nucleoid region instead of a true nucleus, but they are unicellular organisms means they have a single cell. Hence, it is a wrong answer.

Option (b) is given as “helminth”.

The helminths are the multicellular organisms. And each cell has a well-known nucleus. Hence, it is a wrong answer.

Option (c) is given as “protozoan”.

Protozoa belong to domain eukaryotes but are the unicellular microorganisms. So, they contain a nucleus. Hence, it is a wrong answer.

Hence, options (a),(b), and(c) are incorrect.

Conclusion

Hence, viruses are lacking a nucleus, because they do not have cells organelles. Yet,the virushas a nucleic acid, either DNA or RNA.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
