Download file to see previous pages What meaning do these mRNA codons have for protein synthesis? Explanation: mRNA is essential in protein synthesis because it transports genetic information from the DNA contained in the nucleus to its place in the ribosome. In short, mRNA contains the genetic information needed to make proteins during transcription. The protein molecule that results from the process therefore has genetic information identical to the original genetic material of the individual (Clark, Protein Synthesis, 2007). Did the two mutations result in a change in the final proteins? If so, describe the change. Response/ explanation: All mutations will definitely result in the production of different 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 mutation 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 actually manifest as physiological problems in the individual later on (Clark, DNA Mutations, 2007). In general, why might a change in amino acid 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 death (Clark, DNA Mutations, 2007). Part II Punnett Square 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 both meiosis 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 maternal and some have paternal traits. During metaphase I, there is another method of variation and this is known as the independent assortment of homologous chromosome pairs. In anaphase I, there is also variation as there is random mixed variation of maternal and paternal chromosomes. Variation is also produced through fertilization because sex cells from both parents combine in many different ways in order to form a new individual. The chromosomes of the father ...Download file to see next pagesRead More

Mendel and Darwin are the Fathers of Molecular Biology
Mendel performed a simple experiment using a pea plant and 4 o’clock flowers. He first bred the white and purple colored flowers. The first progeny were all purple in color. Mendel went ahead and inbred the pink flowers and the results were astounding. Seventy five percent of the flowers were purple and twenty-five percent were white flowers.

The pathogenetic mechanisms that can arise from these abnormalities include the dosage effect, the direct damaging effect or the position effect, where the gene in a new environment functions inappropriately (1). G-banding of chromosomes is one of the techniques used in cytogenetics.

Restriction Fragment Pleomorphism
There are many DNA based techniques employed for investigation of high risk individual (Bhardwaj 2003) and Restriction Fragment Pleomorphism (RFLP) is one of the most widely used technique.( McCabe 1994). RFLP works on fundamental properties of restriction endonucleases which specifically recognizes pattern of DNA sequence and cleaved it from within.

Role of Phytooestrogen in the Prevention of Breast Cancer
They also are the molecular signals that emanate from the root of leguminous plants that attract specific nitrogen-fixing soil bacteria. The main classes of phytoestrogens are the isoflavones, coumestans and lignans. Lignans are natural plant compounds with estrogenic properties and are probably the most important source of phytoestrogens in western diets.
