Because nucleic acids are normally linear unbranched polymers. Since dna contains the genetic material for an organism it is important that it be copied when a cell divides into daughter cells.

Initiation elongation and termination.
Copying part of a nucleotide sequence of dna. Transcription is the first step towards creating new proteins. The components of the nucleotide used in dna synthesis are a nitrogenous base a deoxyribose and a phosphate group. The replication fork is a structure that forms within the long helical dna during dna replication.
Dna replication is a process that occurs during cellular division where two identical molecules of dna are created from a single molecule of dna. By convention sequences are usually presented from the 5 end to the 3 end for dna the sense strand is used. The monomeric building blocks of dna are deoxyribomononucleotides usually referred to as just nucleotides and dna is formed from linear chains or polymers of these nucleotides.
Deoxyribonucleic acid commonly known as dna is a nucleic acid that has three main components. Process where the information carried by mrna is used to produce proteins. The region of dna that indicates to an enzyme where to bind to make rna.
Transcription is the process of copying part of dna into a new messenger molecule mrna. A deoxyribose sugar a phosphate and a nitrogenous base. The resulting structure has two branching prongs each one made up of a single strand of dna.
Because the double helix is anti parallel and dna. The process in which part of the nucleotide sequence of dna is copied into a complementary sequence in rna. The enzyme that uses one strand of dna as a template to assemble nucleotides into a strand of rna.
Transcription is a three step process of. Copying part of a nucleotide sequence of dna into a complementary sequence in rna describe translation. It is created by helicases which break the hydrogen bonds holding the two dna strands together in the helix.
The process that rna molecules are produced by copying part of the nucleotide sequence of dna into a complementary sequence in rna. Similarly copying the nucleic acid language of dna into the nucleic acid language of rna produces the same document but with some spelling differences in the words ts become us for instance. An enzyme similar to dna polymerase that binds to dna and separates the dna strands during transcription.
As a semiconservative process a single molecule containing two strands of dna in double helix formation is separated where each strand serves as a template for the new dna molecules. A nucleic acid sequence is a succession of bases signified by a series of a set of five different letters that indicate the order of nucleotides forming alleles within a dna using gact or rna gacu molecule. The process that copies dna is called replication.
