I say A because the way the question is formatted it is clear that...
Answer: The correct answer is -
B) The presence of at least one carbon-based sugar.
Explanation:
RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are the two types of nucleic acids that are composed of nucleotide (monomer of nucleic acid).
A nucleotide has three parts, which are pentose sugar (5 carbon sugar), nitrogenous base, and phosphate group.
Starch is a complex carbohydrate as it is composed of several units of simple sugar such as glucose.
Thus, the presence of at least one carbon-based sugar is common in DNA, RNA, and Starch.
Answer:
In gram staining, 95% ethanol is used to destain the gram-negative bacteria but gram-positive bacteria do not get destain because peptidoglycan layer in gram-positive cell wall does not allow crystal violet- iodine complex to come out of the cell wall.
Gram-negative bacteria do not have peptidoglycan cell wall and so crystal violet comes out of the cell wall by using 95% ethanol because ethanol dissolves the lipopolysaccharide membrane of gram-negative bacteria and allow the dye to leak out.
Therefore if I forgot to apply 95% ethanol than crystal violet dye will not come out of the lipopolysaccharide cell wall of gram-negative bacteria and it will appear violet under the microscope.
