Nucleic Acid Diagram Single Strand. Both dna and rna have been shown to consist of three groups of molecules. Deoxy ribonucleic acid dna and ribonucleic acid rna.
The other main difference between rna and dna is that rna is often single stranded and does not form the regular double helical structure of dna. A 1 b 2 c 3 d 4 your answer. Dna in the cell is double stranded meaning that the nucleotides make hydrogen bonds to a complementary dna strand.
The simplest virions consist of two basic components.
In a nucleic acid double helix the direction of the nucleotides in one strand is opposite to their direction in the other strand. Rna molecules often contain both single and double stranded regions. Nucleic acids are the carriers of genetic information. Phosphodiester linkages provide polarity to dna.
