Which structural characteristic is seen in RNA but not in DNA?
A.double strands
B.a single strand
C.chains of nucleotides
D.a helical shape
Answers
DNA or deoxyribonucleic acid is inherently double stranded most of the times.
Whereas ribonucleic acid or RNA is generally single stranded. In addition, the DNA has a helical structure to its double strand which is a characteristic feature of DNA and which is absent in RNA.
These are the main characteristic differences between DNA and RNA
Answer:
A Single-strand structural characteristic is not seen in DNA but seen in RNA.
Explanation:
An RNA is made up of a long chain of nucleotides, has a helical shape and is produced as a single-strand. An RNA is produced during transcription where a double-stranded DNA produces two singe strands of RNA that are complementary to each of the DNA strands.
These single RNA strands are then translated to produce the proteins. In most organisms, RNA is an intermediate product, however certain viruses known as retroviruses have RNA as their ‘genetic material’ instead of DNA.
