Answer :
Both DNA and RNA have similarities and differences:
A. Both DNA and RNA can be single-stranded or double-stranded molecules. DNA is typically double-stranded, forming the iconic double helix structure, while RNA is usually single-stranded.
B. Both DNA and RNA contain nucleotide bases, but they differ in the bases they have. DNA contains the bases adenine (A), thymine (T), cytosine (C), and guanine (G), while RNA contains adenine (A), uracil (U), cytosine (C), and guanine (G). The presence of thymine in DNA is replaced by uracil in RNA.
C. Both DNA and RNA contain phosphate groups. These phosphate groups are essential components of nucleotides, which are the building blocks of DNA and RNA.
D. DNA and RNA have similar five-carbon sugars in their structure, but they are not exactly the same. DNA contains deoxyribose sugar, which has one fewer oxygen atom compared to the ribose sugar found in RNA.
In summary, while DNA and RNA share some common features, such as containing phosphate groups and similar five-carbon sugars, they also have distinct differences in terms of their bases and overall structure.
