DNA is double stranded describes the difference between DNA and RNA.
<u>Explanation:</u>
Deoxyribonucleic acid refers to DNA stands for and ribonucleic acid refers to RNA. Information related to genes is carried by both RNA and DNA. Although they are similar in this way there are many differences that exists between them.
Sugar deoxyribose is contained in DNA whereas the sugar ribose is the content of RNA. Double-stranded molecule is DNA whereas while single-stranded molecule is RNA. In alkaline conditions DNA is stable but RNA is not stable. B-form double helix is the structural feature of DNA. A-form helix structural feature of RNA.
Answer:
Option (D)
Explanation:
Buffers are the chemicals (acid or base) that maintain the level of pH in the living organisms. Different types of buffers that are present in many organisms are bicarbonates ad bi-phosphates.
The phosphate buffer is comprised of inorganic phosphate (HPO₄²⁻) which can bind with free hydrogen when the level of pH is low or in a highly acidic condition. In case of an excessive pH condition or in a basic condition, the phosphates act as a buffer by releasing the hydrogen ions.
Thus, the correct answer is an option (D).
