Answer

Yaa....it is option d ..bcz.
.we know that for dna it is deoxyribonucleic sugar and for rna it is ribonucleic sugar.....
...if we come to 2nd option ...thymine is unique to dna and uracil is unique to rna...
...so they r polymers of nucleotides...
....hope u catch this piont

Answer

DNA and RNA are polymers of nucleotides.
They are made up of 3 nitrogeneous bases -adenine, guanine and cytosine.
They both have phosphate groups in their nucleotides.

Answer

Similarity between DNA and RNA: Polymers of nucleotides

DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are both nucleic acids that play essential roles in the storage and transfer of genetic information in living organisms. They are composed of similar building blocks called nucleotides, which are connected together to form polymers.

DNA structure:
DNA is a double-stranded molecule that consists of two long chains of nucleotides twisted around each other in a double helix structure. Each nucleotide in DNA is composed of three components:
1. Sugar: DNA contains a sugar called deoxyribose, which gives it the name deoxyribonucleic acid.
2. Phosphate group: Each nucleotide in DNA also contains a phosphate group, which forms the backbone of the DNA molecule.
3. Nitrogenous base: There are four different nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair together in a specific manner (A with T and C with G) through hydrogen bonds, forming the rungs of the DNA ladder.

RNA structure:
RNA, on the other hand, is a single-stranded molecule that is typically shorter than DNA. It also consists of nucleotides, but there are some key differences in its structure compared to DNA:
1. Sugar: RNA contains a sugar called ribose, which gives it the name ribonucleic acid.
2. Phosphate group: Like DNA, each nucleotide in RNA contains a phosphate group.
3. Nitrogenous base: RNA has the same nitrogenous bases as DNA, except that thymine is replaced by uracil (U). The base pairing in RNA is A with U and C with G.

Polymers of nucleotides:
Both DNA and RNA are polymers of nucleotides. A nucleotide is composed of a sugar, a phosphate group, and a nitrogenous base. The nucleotides are connected together through a phosphodiester bond, which forms between the phosphate group of one nucleotide and the sugar of the next nucleotide.

In DNA, the nucleotides are linked together to form a long chain, with the sugar-phosphate backbone providing stability and the nitrogenous bases projecting inward. This forms the double helix structure of DNA.

In RNA, the nucleotides are also linked together to form a chain, but it is typically shorter and exists as a single strand. RNA molecules can fold upon themselves to form complex three-dimensional structures, which are crucial for their various functions in gene expression and protein synthesis.

In conclusion, the correct answer is option 'D': DNA and RNA resemble each other in possessing polymers of nucleotides. They are both composed of nucleotides connected together through phosphodiester bonds to form long chains, although they differ in their sugar component, some of the nitrogenous bases, and overall structure.
