Biology

This topic's discussion focuses on the basic processes of howcells are able to do what they do--the central dogma of life. Inorder for cells to function effectively, they need to makeproteins, which, as we learned way back in Topic 2 (Ch. 4) areresponsible for doing all of the work inside of (and for) the cell(enzymes) and provide the necessary structure for cells to function(cytoskeleton, some signaling molecules, binding proteins,receptors, transporters, etc.). Each cell has all of theinformation the organism needs to make these proteins (in the formof genes on chromosomes--the DNA), although it only makes theproteins that it needs when it needs them. The processes of readingthe DNA to make the RNA and reading the RNA to make the proteinsare together known as the central dogma (and sometimes DNAreplication is included since it is also required for livingorganisms to make new cells). Your discussion postings this weekshould focus on some aspect of the central dogma and provide moredetail for your fellow classmates. For example, one of the partsand how it is controlled, where it occurs, what can go wrong, orhow they're connected. Along with the responses, this discussionshould give you a much better understanding of how life actuallyworks! Do not use other solutions. I need originality responses aswell as IN TEXT CITATIONS AND A WORKS CITED REFERENCE. Please use 2outside references.Thank you

Central dogma includes processes like replication transcription and translation Replication of DNA is accomplished by the polymerisation of deoxyribonucleotides into new DNA strands each synthesized on the template of one of the strands of a preexisting DNA duplex Nuclear DNA is replicated during the S phase of the cell cylce In the daughter cell one strand is derived from the mother cell while the other strand is newly synthesized the process called semiconservative replication Details Replication can be semiconservative bidirectional or semidiscontinuous The DNA replication starts with the recognition of the site of origin of replication called replication fork DNA replication needs participation of more than 20 enzymes and proteins called DNA replicase system or replisomes Unwinding of DNa is brought about by Rep protein DNA helicase II and helixdestabilising single stranded binding protein SSBprotein The protein A or DnaA binds at specific sites of origin and opens the duplex The toisomerase enzymes also called nickingclosing enzymes DNA swivelases and DNA gyrase nick the strands of the DNA and catalyse the uncoiling and supercoiling of the duplex The    See Answer
