Answer:
The correct answer will be- 200
Explanation:
The cell cycle in eukaryotes mostly takes place in four phases: G₁, S, G₂ and M phase in sequence.
The DNA replication takes place during S phase which doubles the amount of DNA in a cell after which during M- phase the DNA divides into the daughter cell.
The amount of DNA present during G₂ phase is the 200 pg which will remain same until anaphase I as the segregation of chromosomes to the daughter cells takes place in the anaphase. Therefore, the amount of DNA observed after G₂ phase will remain 200 pg till metaphase I.
Thus, 200 is the correct answer.
Answer:
Why antibiotic-associated diarrhea occurs isn't completely understood. It's commonly thought to develop when antibacterial medications (antibiotics) upset the balance of good and bad bacteria in your gastrointestinal tract.
Explanation:
Answer:
It is a compound sentence.
Explanation:
Compound sentence contains two independent clauses.
Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.
- All bacteria indicated in the question can be classified by the Gram staining test:
- Actinomycetes are Gram-positive bacteria
- The genus <em>Arthrobacter </em>includes Gram-positive bacteria
- <em>Escherichia coli </em>(<em>E. coli</em>) is a Gram-negative bacterium
- <em>Staphylococcus spp.</em> are Gram-positive bacteria
- <em>Bacillus spp</em> are Gram-positive bacteria
- <em>Mycobacterium spp.</em> are Gram-positive bacteria
- Prokaryotes can be divided into two domains: Bacteria and Archaea.
- Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.
- In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).
- Archaebacteria belong to the Archaea domain.
