RNA strands are created using DNA strands as a template in a process called transcription.A large part of DNA (more than 98% for humans) is non-coding, meaning that these sections do not serve as patterns for protein sequences.The two strands of DNA run in opposite directions to each other and are thus antiparallel.
The nitrogenous bases of the two separate polynucleotide strands are bound together (according to base pairing rules (A with T, and C with G) with hydrogen bonds to make double-stranded DNA.
The total amount of related DNA base pairs on Earth is estimated at 5.0 x 10 DNA stores biological information.
The DNA backbone is resistant to cleavage, and both strands of the double-stranded structure store the same biological information.
This information is replicated as and when the two strands separate.
Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix.The two DNA strands are termed polynucleotides since they are composed of simpler monomer units called nucleotides.
