GENETICS AND GENE MUTATION Coursework Example | Topics and Well Written Essays - 750 words

GENETICS AND GENE MUTATION - Coursework fountWhat meaning do these mRNA codons have for protein deduction? chronicle mRNA is essential in protein synthesis because it transports catching information from the DNA contained in the nucleus to its place in the ribosome. In short, mRNA contains the genic information needed to make proteins during transcription. The protein molecule that results from the process therefore has genetic information identical to the received genetic material of the individual (Clark, Protein Synthesis, 2007). Did the two athleticss result in a change in the closing proteins? If so, describe the change. Response/ explanation All mutations will definitely result in the production of polar final proteins, such as the changes caused by the three mutations in the diagram above. Specifically, the two genetic mutations above were significant. In the first mutation, the mutation coded for ILE when in fact MET should be the normal initiation code. The second m utation coded for ASP and PRO instead of HIS and ARG when the gene is normal. However, the third mutation is not that significant since UAA is also a termination codon just like UGA. Such mutations that result in significant changes in proteins may in reality manifest as physiological problems in the individual later on (Clark, DNA Mutations, 2007). In general, wherefore might a change in amino window pane sequence affect protein function? Explanation Protein function may be affected even by slight changes in amino acid sequence. This happens in protein synthesis. These changes may manifest as genetic disorders in the individual or even last (Clark, DNA Mutations, 2007). Part II Punnett Square a. Chances (%) for healthy child, not a newsboy b. Chances (%) for child that is carrier for cystic fibrosis trait c. Chances (%) for child with cystic fibrosis Fill out/adapt Punnett Square ___C___ __c___ ___C___ CC Cc ___c___ Cc cc a. Chances (%) for healthy child, not a carrier 25% (CC ) b. % for child that is carrier for cystic fibrosis trait 50% (Cc) c. % for child with cystic fibrosis 25% (cc) Part III Essay How do some(prenominal) reduction division and sexual reproduction (fertilization) produce offspring that differ genetically from the parents? Include steps in meiosis that increase variability Include the process of fertilization. Explanation Crossing over, or the exchange of genetic material, which takes place during meiosis is responsible for the variation that may show up in the offspring. Prophase I of meiosis is the one responsible for crossing over. The result of this particular process is the production of chromosomes, some of which have enate and some have paternal traits. During metaphase I, there is another method of variation and this is known as the self-supporting assortment of homologous chromosome pairs. In anaphase I, there is also variation as there is random tangled variation of maternal and paternal chromosomes. Variation is also pr oduced through fertilization because sex cells from both parents heighten in many different ways in order to form a new individual. The chromosomes of the produce
