Transcription and Translation Notes for IB Diploma Year 1 DNA is a huge information database that carries the complete set of instructions for making all the proteins a cell will ever need! Although there are only four different bases in DNA (A‚ C‚ G and T)‚ the order in which the bases occur determines the information to make a protein‚ just like the 26 letters of the alphabet combine to form words and sentences: Compare: RAT - TAR - ART - same 3 letters; completely different meanings. And

Transcription factors deregulation in the differentiation of chronic myeloid leukemia stem cells was demonstrated in a transgenic model with deficiency of a transcription factor Jun B. Jun B deficiency‚ led to the development of a chronic myeloid leukemia like disease with a propensity for myeloid differentiation in which several transcription potential exist only at the level of HSC‚ according to NCBI. GM-CSF is a mediate

RNA. 14. What is the role of mRNA? 15. What is transcription? 16. What is translation? 17. What does it mean to say the genetic code is unambiguous? 18. What role is performed by transfer RNA? 19. If a DNA strand is represented by the bases: A-C-T-G-G-C what are the bases that will be included in the replicated strand? 20. If a DNA strand is A-C-T-G-G-C‚ what is the base representation that will be produced by transcription? 21. If a messenger RNA molecule is U-C-A-A-C-G what

Lead Toxicity Has No Felicity For centuries‚ Lead (Pb) has been used in various industries—most notoriously‚ the paint industry—and although lead-based paint has been significantly reduced in developed regions‚ it still infiltrates many American homes concentrated in low-income areas. Studies have shown that lead is able to mimic certain metals that are significant in biological processes‚ leading to a collection of developmental and physiological conditions commonly grouped as “lead poisoning.”

MYC- is a mutated MYC MYC participates in the regulation of gene transcription. It binds to DNA in a non-specific manner. MYC controls genetic information flow from DNA to the mrna and plays an important role in controlling cell division. “That role is so powerful that cells co-evolved an emergency death pathway to keep c-Myc expression in check. If c-Myc’s production spins out of control in an otherwise normal cell‚ the cell immediately commits suicide through a process called apoptosis. But in

The nucleolus (plural nucleoli) is a non-membrane bound structure. Composed of proteins and nucleic acids found within the nucleus. Ribosomal RNA (rRNA) is transcribed and assembled within the nucleolus. Three major components of the nucleolus are recognized: the fibrillar centers (FC)‚ the dense fibrillar components (DFC)‚ and granular components (GC). The DFC consists of newly transcribed rRNA bound to ribosomal proteins‚ while the GC‚ contains rRNA bound to ribosomal proteins that are beginning

speed at which things can transpire of be completed. For example‚ over twenty years ago the legal transcription industry was very different than today mainly because of the many advances in speech recognition technology. As speech recognition technology continues to improve and increase in popularity‚ it will continue to change the transcription industry a steep decline in the number of legal transcription jobs available. The advances in the computer industry have also contributed to the decline in the
