Nucleotides and genes
WebWe isolated the mouse EF-2 gene and characterized its promoter. We showed that the majority of enhancer elements were located within 500 bp of the flanking sequence and identified a factor binding site sequence (CGTCACGT-GACGC) located between nucleotides -58 and -47 containing two CGTCA motifs separated by two nucleotides.

WebGenomes Consist of DNA Molecules That Contain Many Genes. The genome of all living organisms consists of DNA, a very long two-stranded chemical polymer ().Each DNA … Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver.

WebThe gene encoding the lipoprotein MslA in Mycoplasma gallisepticum has recently been shown to be required for virulence, but the biochemical function of this gene is not known. Although this gene has no significant sequence similarity to any gene of known function, it is located within an operon in M. gallisepticum that contains a homolog of a gene …
WebIn double stranded DNA, paired G and C nucleotides are joined by three hydrogen bonds, while the A and T have only two. This means that CG pairs are "stronger" than AT pairs, and thus the ratio of GC to AT for a DNA sequence has a marked effect on its physical properties (such as its "melting point").
