Glucose isomerase is intracellular enzyme that. enzyme converts glucose into fructose which is a much sweeter carbohydrate. (a) Explain how proteins like glucose isomerase made in cells? (5 marks) - answer-( careful mention process of DNA unwinding ) DNA = unzips ===> break H-bonds --> use DNA helicase transcription, make mRNA, RNA polymerase, CBPairing (ii) Explain why some bases in gene do not code for amino acids? (2 marks) - answer-some start + stop co...

BTEC APPLIED SCIENCE UNIT 11 Genetics and Genetic Engineering – Learning Aim D. You are applying to do work experience in a molecular biology laboratory. As part of the application process, you have been asked to produce an illustrative report to demonstrate your understanding of DNA, RNA and protein synthesis and the consequences of error occurring in protein synthesis. Task Produce an illustrated report that assesses the impact of error in the stages of protein synthesis, discusses the...

How DNA sequencing got started - answer-Sanger first did it using radioactive labelling of bases and gel electrophoresis, done manually so took lots of time, radioactive bases swapped for fluorescent bases, led to automation and scaling up of process, led to capillary sequencing used in HGP Principles of DNA sequencing - answer-DNA mixed with different chemicals, PCR carried out in a thermal cycler, DNA polymerase builds up new strand with the nucleotides as part of PCR, addition of terminato...

Provide an illustrated report that assesses the impact of error in the stages of protein synthesis, discusses the functional role of nucleic acids in the stages of protein synthesis and explains the structure and function of nucleic acids. Explain the nucleotide structure and main features of the following nucleic acids: DNA- stages and enzymes involved in DNA replication. RNA- mRNA, tRNA, rRNA, and siRNA. Discuss the functional role of these nucleic acids in protein synthesis and the...
