which of me following characteristics. structures. or processes is common to both bacteria and viruses?
- A.
metabolism - B. ribosomes
- C. genetic material composed of
nucleic acid - D. cell division
Introduction:
Bacteria are single-celled micro-organisms that are present in diverse environments. Most of them are harmless and inhabit the human intestine. Bacterial infections include tuberculosis, strep throat, urinary tract infections, and others. Viruses are smaller in size than bacteria and they require a living host for their survival. Common cold, chicken pox, and herpes are some of the diseases caused by viruses.
Answer to Problem 1TYU
Correct answer:
The property that is common to both viruses and bacteria is that their genetic material is made up of nucleic acids, which are made up of nucleotides and serves as the heredity transferring material in both the organisms. Therefore, option (C) is the correct.
Explanation of Solution
Reason for the correct statement:
Bacteria are independent of other organisms for their growth and survival. Whereas, viruses depend on the host cell for their growth and replication. The genetic material of bacteria floats freely in the cytoplasm of the cell, whereas the genetic material of viruses is covered by a protein coat called capsid.
Option (C) is given as “genetic material is composed of nucleic acids”.
“The genetic material which is composed of nucleic acid is common to both bacteria and viruses” is the right answer.
Hence, option (C) is correct.
Reasons for the incorrect statement:
Option (A) is given as “metabolism”.
Viruses do not have their own metabolic machinery. They depend on the host’s metabolic machinery for their metabolism. However, bacteria have their own metabolic machinery and hence they are able to carry out all their metabolic functions. Hence, it is the wrong answer.
Option (B) is given as “ribosomes”.
Bacteria consist of ribosomes whereas viruses lack ribosomes. Hence, they cannot synthesize proteins and they depend on host cells. Therefore, it is the wrong answer.
Option (D) is given as “cell division”.
The bacterial cell divides by fission. However, viruses depend on the host cell in order to produce multiple copies and the process of assembly also occurs in the host. Hence, it is the wrong answer.
Hence, options (A), (B), and (D) are incorrect.
Like bacteria, viral genetic information is also coded in the form of nucleic acids. Hence, this is the characteristic that is common to both the microbes.

Can you tell…arrow_forwardYou have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forward
