RNA is usually single-stranded, while DNA is usually double-stranded. In addition, RNA contains ribose while DNA contains deoxyribose. Deoxyribose lacks one oxygen atom. RNA has the bases Adenine (A), Uracil (U) (instead of thymine in DNA), Cytosine (C) and Guanine (G).

The correct answer is option 'A' - Uracil, Ribose.

RNA (ribonucleic acid) is a nucleic acid that plays a crucial role in gene expression and protein synthesis. It is composed of nucleotides, which consist of three main components: a nitrogenous base, a five-carbon sugar (ribose), and a phosphate group. There are four types of nitrogenous bases found in RNA: adenine (A), guanine (G), cytosine (C), and uracil (U).

Here is a detailed explanation of why option 'A' is the correct answer:

1. RNA Structure:
- RNA is a single-stranded molecule, unlike DNA (deoxyribonucleic acid) which is double-stranded.
- The backbone of RNA is formed by the sugar-phosphate groups, whereas the nitrogenous bases protrude from the backbone.

2. Nitrogenous Bases in RNA:
- Adenine (A): It pairs with uracil (U) in RNA. In DNA, adenine pairs with thymine (T).
- Guanine (G): It pairs with cytosine (C) in both RNA and DNA.
- Cytosine (C): It pairs with guanine (G) in both RNA and DNA.
- Uracil (U): It is found only in RNA and replaces thymine (T) found in DNA.

3. Ribose Sugar:
- Ribose is a five-carbon sugar that forms the backbone of RNA.
- It is a pentose sugar, meaning it has five carbon atoms.
- The sugar is attached to the nitrogenous base at the 1' carbon position.

Based on the above information, option 'A' is the correct answer because it includes uracil as one of the nitrogenous bases found in RNA and ribose as the sugar component of RNA. The other options are incorrect because they either include nitrogenous bases or sugars that are not present in RNA.

In conclusion, RNA contains uracil as one of its nitrogenous bases and ribose as its sugar component. These components play a crucial role in the structure and function of RNA in various cellular processes.

Read the passage given below and answer the following questions:Adenosine triphosphate (ATP) is the energy carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis). Usually only the outer phosphate is removed from ATP to yield energy; when this occurs ATP is converted to adenosine diphosphate (ADP), the form of the nucleotide having only two phosphates.The importance of ATP (adenosine triphosphat e) as the main source of chemical energy in living matter and its involvement in cellular processes has long been recognized. The primary mechanism whereby higher organisms, including humans, generate ATP is through mitochondrial oxidative phosphorylation. For the majority of organs, the main metabolic fuel is glucose, which in the presence of oxygen undergoes complete combustion to CO2 and H2O: C6H12O6 + 6O2 → 6O2 + 6H2O + energyThe free energy (ΔG) liberated in this exergonic (ΔG is negative) reaction is partially trapped as ATP in two consecutive processes: glycolysis (cytosol) and oxidative phosphorylation (mitochondri
