DNA is the carrier of genetic information, its parent DNA molecule must be copied exactly into two

DNA (Deoxyribonucleic cannabis acid), cannabis Chinese name of DNA, known as DNA, single-stranded by two vines such as double intertwined helical structure (see Figure 2), such a nucleic acid polymer is determined by dideoxy linked to a nucleotide sequence, by part of each deoxynucleotide deoxyribose phosphate molecule, and a nucleotide molecule (see Figure 1). There are four different DNA bases are adenine (adenine, abbreviated as A), thymidine (thymine, abbreviated as T), cytosine (cytosine, abbreviated as C) and guanine (guanine, abbreviated as G) .
DNA is the carrier of genetic information, its parent DNA molecule must be copied exactly into two copies of the template, and assigned to two daughter cells (see Figure 3), the carrier of genetic information to complete its mission. Thus, DNA is also referred to as "Genetic Particle." And double-stranded DNA replication for the maintenance of stability cannabis and accuracy of such genetic material are extremely important. DNA is a molecule that can form the genetic instructions to guide biological development and operation of vital functions. The main feature is a long-term information storage, can be likened to a "blueprint" or "recipes." cannabis Wherein the instructions contained in the cells of other compounds, such as the construction of the desired protein and RNA. DNA fragments of genes with known genetic information, other DNA sequences, some direct role in their structure, cannabis and some are involved in regulation of expression of genetic cannabis information.
