This chapter discusses components of nucleotides, DNA, and protein synthesis. Genetic information is stored in DNA in the nucleus and mitochondria of cells. DNA consists of two strands of nucleotides on a phospho deoxyribose backbone. The two strands form a double helix that is stabilized by the...
containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA is self-replicating, plays a central role in protein synthesis, and is responsible for the transmission of hereditary characteristics from parents ...
Protein synthesis is a two step process.DNA —(transcription)→ RNA —(translation)→ PolypeptideTranscription happens when the information from the DNA template is transcribed onto another form of nucleic acid known as ribonucleic acid or RNA (actually messenger RNA)....
DNA synthesis assessed in axenic media supports the limited protein biosynthesis data We then tested if the axenic media also promoted DNA synthesis (Fig.7).3H thymidine incorporation was measured in the axenic media along with35S Cys-Met incorporation to assess DNA and protein synthesis, respectivel...

whileDNAreplication is the synthesis of a new DNA molecule from an existing DNA molecule. While these two processes have a few similarities between them, there are also several differences in their mechanism as well as the final product. These are the differences between p...
Cyanuric acid, a small molecule with three thymine-like faces, reprogrammes the assembly of unmodified poly(adenine) into long fibres with a unique internal structure. The association of adenine and cyanuric acid units into a hexameric rosette motif brings together poly(adenine) triplexes with subse...

与DNA转录和翻译不同的是,DNA复制一般不能从头合成(De novo synthesis),只能在事先合成好的引物(primer)的3′-羟基上进行DNA链的延伸。通常作为引物的是长度为7～15nt的短RNA,少数为蛋白质。在DNA复制到一定阶段,RNA引物最终会被切除。留下的空隙会被补上相应的DNA序列。至于为什么DNA复制需要先合成RNA引物、...
