Answer:
The correct answer is D. A gram-negative cell wall consists of a thin layer of peptidoglycan surrounded by an outer membrane containing lipopolysaccharides.
Explanation:
Gram-negative bacteria are bacteria that do not retain the gentian violet dye during the Gram staining protocol.
During the Gram staining process, a contrast dye, usually safranin, is added after gentian violet, causing the Gram negative bacteria to stain pink or red. The contrast dye thus allows the visualization of Gram-negative bacteria which, because they have a thinner layer of peptidoglycans, cannot retain the gentian violet dye.
Its main feature is an endotoxin called lipopolysaccharide that causes pathogenicity and is responsible for its virulence.
The sequence of bases on RNA that would match or pair with the following DNA sequence: GCA is CGU.
<h3>What is transcription?</h3>
Transcription is the process by which mRNA sequence is produced from a DNA template in the nucleus of a cell.
During transcription process, the following applies:
- Adenine (A) pairs with Uracil (U)
- Guanine (G) pairs with Cytosine (C)
This means that the mRNA sequence that will result from a template of DNA with sequence: GCA is CGU.
