DNA is called upon to serve a specific function. One crucial role of DNA is replication. The double helix structure of the DNA molecule allows the disconnection of the strands to bind with newly developing DNA molecules. The double helix can pave the way to an indefinite number of DNA molecules as long as the replication process continues.
There are a few nitrogenous bases that permit the molecule to be arranged in a manner by which a code is created. RNA is nucleic acid consisting of a long chain of nucleotide units. Like the DNA molecule, every nucleotide consists of a nitrogenous base, sugar, and phosphates. RNA is generated by a process entitled, transcribing.
Nucleotides lead to the RNA pair with the corresponding base, and spirals form into the backbone. Eventually, the untwisted bonds that occur between RNA and the unzipped DNA bonds break, and the newly created RNA leaves through the nuclear pores.
