1. Write an essay on protein structure and synthesis Protein synthesis is a cellular process leading to the production of proteins. This term is also synonymous to protein translation. It begins with a sequential process of transcription of DNA into mRNA, which is then used as input for translation after exon-intron splicing. The addition of successive tRNA molecules based on the code of mRNA matched up by base-pairing through their anti-codons in the ribosomes creates the nascent protein. After the protein chain has been synthesized, post-translation modification occurs, e.g. phosphorylation, motifs added to the protein. This may happen at various levels: secondary (alpha-helix, beta-sheets, turn, random coiling), tertiary and†¦show more content†¦It happens in stages. First, a signalling molecule activates a receptor on the membrane. Second, a second messenger that will perpetuate the signal into the cell will bne activated to elicit a physiological response. Examples of such process involve cAMP, calcium signaling, and kina ses. 4. Write an essay on the uses of polymerase chain reaction in molecular biology The polymerase chain reaction (or PCR) is a molecular technique for the amplifyication of a single or a few copies of DNA strands across several orders of magnitude, generating thousands to even millions of copies of a particular DNA strand with the specific primers and a thermo-resistant polymerase enzyme. This powerful technique is being applied in medicine, eg, detection of gene mutation in cancers and tailoring of therapies; infectious diseases,eg detection of pathogens and infections; agriculture, analysis of cultuvars; and forensics, eg identification of criminal from sperm during rape cases. The polymerase chain reaction in molecular biology also allows scientist and medical professionals to replicate copies of specific DNA sequences in millions in a matter of few hours. In plain language, this allows researchers to photocopy or Xerox specific DNA sequences in a short period of time. They to replicating or duplicating specific DNA sequences however is a familiarity of a part of the sequence of the DNA molecules. This primers can be later synthesized toShow MoreRelatedThe Integration Of Computers And Software Tools940 Words   |  4 Pagescrucial for biological investigation. Consequently, bioinformatics has been established as a major discipline in molecular biology. It encompasses a numerous subject areas, such as structural biology and genomics to more complex areas such as gene expression studies. However, bioinformatics is commonly confused with a discipline of science known as computational biology. Computational biology is the development and application of theoretical and analytical methods, which are combined with mathematicalRead MoreSample Resume : School Of Science Health1613 Words   |  7 Pagesright to not mark this assignment if the above declaration has not been signed.

Is a disease caused by a pathogenic microorganism, a to xic agent in the environment, or a faulty gene? My interest in molecular biology has been inspired by these questions and led me to the world of genetics. While I was an elementary student, my mother was diagnosed with cervical cancer. From that situation, I developed an insatiable curiosity for cancer and molecular medicine. I am particularly interested in gene structure and function and genetic analysis of cancer, a broad group of diseasesRead MoreThe, No Bread For Thanksgiving1148 Words   |  5 Pagesceliac disease, is better understood. Advanced methods in molecular biology have allowed scientists to increase their knowledge of how coeliac disease works. Coeliac disease is an autoimmune disease, meaning that the body’s immune system is responsible for the ill symptoms by attacking the body’s cells. This is different from an allergy, in that basophils and eosinophil are specifically responsible for allergic responses (Celiac Disease Foundation). When an individual with coeliac disease consumes wheatRead MoreModern Medicine And Technology As A Research Assistant At The Piano Laboratory992 Words   |  4 Pagesapplications of research towards patient care. Working as a Research Assistant at the Piano Laboratory, I have an interest in developmental biology. At the Piano Lab, I assist my mentor, Patricia Giselle Cipriani, and her project on the usage of RNAi on ovary-expressed genes and of time-lapse microscopy in order to better understand a comprehensive molecular description of the genetic and evolutionary mechanisms behind early embryogenesis in C. elegans. From the data obtained from the RNAi testsRead MoreWhat Is Biochemistry699 Words   |  3 Pagesof their chemical component such as proteins ,carbohydrates, lipids, and nucleic acids. Many of these molecules are complex molecules called polymers, which are made up of monomer subunits. Most people consider biochemistry to be same with molecular biology. Nowadays, biochemistry has become the root for understanding all biological processes. It has provided widely explanations for the causes of many diseases in humans, animals and plants. As a student, we should study it because it give toRead MoreHuman Genetics And Molecular Mechanisms1657 Words   |  7 Pagesfurther pursue my interest in biological sciences. To learn more about human genetics and molecular mechanisms involved in the various genetic disorders, I decided to pursue a comprehensive undergraduate course at Pt.
