Question

Which of the following is correct?
A. All fungi are filamentous.
B. Transfer of DNA from one bacteria to another bacteria cannot take place.
C. Viruses have only DNA as genetic material.
D. None of the above

Answer 1

Hint: Filamentous fungi are regularly saprophytic microorganisms which emit a wide exhibition of proteins associated with the decay and reusing of complex biopolymers from both plant and creature tissues. Most microscopic organisms have a haploid genome, a solitary chromosome consisting of a roundabout, twofold abandoned DNA atom.

Complete answer:
A) Fungi have a filamentous structure called hyphae. The hyphae are long chains of cells joined start to finish by cross dividers called septa (septate) or without septa (aseptate). In any case, a few organisms like Yeast do not frame hyphae and are single-celled. Along these lines, all parasites are not filamentous.
B) Transfer of hereditary material from one bacterium to others can happen by the accompanying techniques:
1. Transformation: It is the cycle in microscopic organisms by which free DNA is joined into a beneficiary cell from the encompassing as exposed DNA.
2. Transduction-It is the cycle by which DNA is moved from one cell to another by a bacterial infection.
3. Conjugation: It is the cycle of the move of the hereditary material starting with one cell then onto the next by methods for a formation tube.
Along these lines, the DNA move can happen from one bacterium to another.
C) Viruses contain hereditary material encased in a protein capsid. The hereditary material could be either DNA or RNA yet not both.

Hence, the correct answer is option (D).

Note: The fungi can develop filamentous hyphal cells. There are additionally single-celled parasites (yeasts) that do not shape hyphae, and a few growths have both hyphal and yeast structures. Transduction happens when a bacteriophage containing bacterial DNA contaminates a beneficiary bacterium and moves this bacterial DNA to the beneficiary bacterial host cell. This moved bacterial DNA may then be fused into the genome of the beneficiary bacterium. A virus is a little assortment of hereditary code, either DNA or RNA, encircled by a protein coat. A virus cannot reproduce alone.
