develop genetic map, molecular markers, or first blackberry expressed sequence tag (EST) library. The newly release of two blackberry (Rubus L) cultivars with new trait, primocane fruiting has the potential to expand the industry by combining primocane fruiting with useful trait such as thornlessness. To compensate lacking of molecular linkage map and molecular marker, simple sequence repeat (SSR) has been generated from strawberry EST sequences from Genbank. Strawberry is a related species with blackberry
A) Expressed Sequence Tag (EST) Analysis There are huge numbers of genes in our genome yet only few of them express to synthesis mRNAs which encode different proteins. These mRNAs are collectively called as transcriptome and mRNA can be reverse transcribed into cDNA, which provides evidence for all mRNA transcripts. Hence, mRNA and cDNA are crucial for gene expression profiling and transcriptome study. Expressed sequence tags (ESTs) are short, unverified nucleotide fragment usually of 200-800 nucleotide
hence give a picture of this protein’s evolution and distribution through the vertebrate species. In this study, a cDNA sequence encoding the transferrin of the Asian seabass (Lates calcarifer) was identified and analyzed using in silico approaches to predict and characterize its functions. The study of teleost fish proteins is important as there are a very limited number of sequences of this fish available in the database thus limiting the study of this group of fishes. With the ongoing efforts to identify

Sequence and structural proteomics involve the large scale analysis of protein structure. Comparison among the sequence and structure of the protein enable the identification on the function of newly discovered genes (Proteoconsult, n.d.). It consists of two parallel goals which one of the goals is to determine three-dimensional structures of proteins. Determine the structure of the protein help to modeled many other structures by using computational techniques (Christendat et al., 2000). This approach
the genome.” In other words, the epigenome tells the genome what to do (i.e. what genes to activate, silence, etc). The process occurs via epigenetic changes – covalent modifications to the genome, that don’t actually change the DNA sequence itself, but simply leave tags that control gene expression. Epigenetic changes occur via two processes. The first is by chemically altering the DNA molecule by adding a methyl
which synthesizes aquorin, a chemiluminescent protein. It is a luciferase that catalyses coelenterazine oxidation through a calcium dependent reaction to emit blue light and green fluorescence under UV light. Soon after, it was cloned and GFP was expressed in bacteria (Williams, Slatko and McCarrey, 2007). Luciferase is a bacterial reporter found in some species like the Photobacterium. The bioluminescence is produced from the dehydration of hydroflavin intermediate, producing blue/green light. Mutations
Cancer is beyond mutations. By definition, epigenetics is the change in gene translation that is caused by alterations not directly due to genetic mutations in the DNA sequence. The 2 main mechanisms are DNA methylation and covalent modification of histones. By methylation, certain molecular tags (methyl groups) bind to a specific sequence of a gene, that results in its disability hence incapable of being translated into its appropriate protein product. These changes affect the cell’s functions leaving
There are various methods that have been developed over these years to study protein-protein interactions (PPIs). PPI plays a big role in the cell-signalling cascade; for instance, dephosphorylation of glycogen synthase by protein phosphatase-1 results in glycogen synthesis. To know whether a specific protein binds to its partner, for example, whether TFIIH interacts with TFIIE or TFIIF to complete the pre-initiation complex in transcription, different methods such as co-immunoprecipitation (co-IP)
Ethical Issues of Genetic Screening Introduction As we approach the 21st century, we as a society are increasingly bombarded with technical advances. One such area of advancement is the research involved with the Human Genome Mapping Project (HGMP). HGMP is a multi-billion dollar world wide research collaboration interested in sequencing the entire human genome. Started on October 1, 1990, with a group of over 350 labs, and expected to finish within the next 5 to 7 years, the Human Genome
Gene Patenting What is gene patenting? Before you can investigate into gene patenting, one must understand what genes are and what the importance of genes. Genes are proteins and molecules that make up the DNA of everything around us. In essence, they are ingredients that complete everything we touch, feel, or see. We recognize genes as a part of the human DNA. Genes can determine a person’s race, sex, and even how healthy we are. Genetics have multiple purposes. The main purposes of commonly recognized
All living things depend on a source of energy for their survival. These sources may vary from one species to another. For example, human’s and animal’s main source of energy is food, while plants main source of energy is sunlight. Plants lack the ability to move and look for sources of energy, runaway from predators, or avoid Abiotic stress. Instead, they have Photoreceptors such as chlorophyll found in plants’ chloroplasts which absorbs light and changes it into a cascade of electron transfer that
compliments—are frequently expressed by highly predictable and stereotyped linguistic routines. They combine verbal material and social messages in patterns, expressive of cultural values and sensitive to interactional context” (Bonvillain 2014, 86). There are routine exchanges within this conversation which occurred outside of the participant’s conversation due to the setting of the conversation. Since the participants ' were at work where they use routines which “typically occur sequences of exchanges between
Shahed Al Massri 250 572 285 Dr. Torchia Take Home Exam November 4th, 2014 Question 1 Epigenetic inheritance is defined as the regulatory information passed down from parent to offspring without any changes in the underlying DNA sequence. This process can involve various modifications of histones as well as DNA itself. These types of alterations include acetylation, methylation and phosphorylation. Such changes can regulate expression through a variety of different mechanisms, including
Introduction Sleep is defined as a reversible, natural state of reduced responsiveness to external stimuli and relative inactivity, accompanied by a loss of consciousness1. This state of inactivity has been evolutionary conserved across species against many selection pressures. This suggests that sleep holds a vital function. Multiple studies have suggested that sleep enhances both declarative and procedural memory 2,3. Consequently, memory consolidation is one of the ostensible functions of sleep
