nukleiinihappoketjun

Nukleiinihappoketjun refers to a single strand of a nucleic acid molecule. Nucleic acids, such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are essential biomolecules involved in storing and transmitting genetic information. A nucleic acid molecule is typically composed of repeating units called nucleotides. Each nucleotide consists of a phosphate group, a sugar molecule (deoxyribose in DNA, ribose in RNA), and a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil).

In DNA, a nucleic acid molecule is usually double-stranded, with two complementary strands wound around each other in a double helix. In contrast, RNA molecules are typically single-stranded, although they can fold upon themselves to form complex three-dimensional structures. Therefore, a nukleiinihappoketjun specifically denotes one of these individual strands. The sequence of nucleotides within a nukleiinihappoketjun determines the genetic code, dictating the synthesis of proteins and regulating cellular functions. The stability and interactions of these chains are fundamental to life processes.
