Which type of nucleic acid is typically composed of only one strand of nucleotides?
A
DNA (deoxyribonucleic acid)
B
Neither DNA nor RNA
C
Both DNA and RNA
D
RNA (ribonucleic acid)
Verified step by step guidance1
Understand the structure of nucleic acids: DNA (deoxyribonucleic acid) is typically double-stranded, forming a double helix, while RNA (ribonucleic acid) is usually single-stranded.
Recall the key differences between DNA and RNA: DNA contains the sugar deoxyribose and the base thymine, whereas RNA contains the sugar ribose and the base uracil.
Consider the biological roles of RNA: RNA is single-stranded to allow flexibility in its functions, such as coding, decoding, regulation, and expression of genes.
Eliminate incorrect options: 'Neither DNA nor RNA' is incorrect because RNA is single-stranded, and 'Both DNA and RNA' is incorrect because DNA is double-stranded.
Conclude that RNA (ribonucleic acid) is the correct answer, as it is typically composed of only one strand of nucleotides.
