    A eukaryote is a single-celled or multicellular organism that contains a membrane bound nucleus. A eukaryotic cell has a nucleus that entraps the DNA unlike the prokaryotic cell that lets it be free. A prokaryote is also known as bacteria. The DNA roams freely inside of the cell. Eukaryotic cells are large meanwhile prokaryotic cells are much smaller. There are many differences about the prokaryotes and eukaryotes cells. The DNA replication of a eukaryotic cell would be two chains held together…

    components of coenzymes and proteins (Axtell). Controlling gene expression via miRNA is the plant’s way of responding to limiting levels of these essential macronutrients. miRNA works by binding to single stranded mRNA which creates double stranded RNA. Thus the plant identifies the new double stranded mRNA as inferior and attacks it. For the experiment, there were four microRNAs used including miR156, miR395, miR398, and miR399. miR156 was the control and has no nutrient requirement so it…

    increased gene expression level or gene function. DS presents altered pattern of DNA methylation in genes in two or three copies with functional differences in gene expression. Studies show trisomy 21 results in altered expression of microRNAs (noncoding RNA involved in post-transcriptional gene regulation, possibly result in abnormal expression of specific proteins and contribute to the DS phenotype. Phenotypes vary, but dysfiguration of physical features and ability to learn are observed in…

    an open complex from there a lagging strand will develop along the 3’ template strand due to the polarity and orientation of the strands. A leading strand will emerge and DNA polymerase enlists nucleotides to pair with the exposed DNA template while RNA primer provides a 5’ end for nucleotides to pair with on the laggings strand. This continues until all the DNA is replicated, once the DNA is copied over what exists are tandem repeats called concatemers. To turn the lagging strand…

    Neuroblastoma and microRNA- 34a is commonly mentioned together in many articles and studies around the world. With the advance in medicine and new discoveries, there has been found a dependence relation of neuroblastoma with these specific type of microRNA since it has been discovered how it could eliminate cancer eternally. MicroRNA-34a has not only revolutionized scientists but the world in general because of its ability to destroy neuroblastoma but also because is a new natural genetic…

    The Violinist Thumb is a book by Sam Kean that describes how DNA, and heredity function. The book is divided into four parts. Part one describes the basics of heredity. It goes into detail about base pairs, amino acids, RNA, and the such to give readers an overview of the system of heredity. One of my favorite stories from part one is the story of Tsutomu Yamaguchi, who survived both atomic explosions in Japan during World War II, and lived into his nineties. Part two discusses adaptations,…

    Protein structure prediction is that the prediction of the three-dimensional structure of a protein from its organic compound sequence — that's, the prediction of its folding and its secondary, tertiary, and quaternary structure from its primary structure. Structure prediction is essentially totally different from the inverse downside of protein style. protein structure prediction is one among the foremost necessary goals pursued by bioinformatics and theoretical chemistry; it's extremely…

    their DNA2. Prokaryotic DNA replication occurs in the cytoplasm and there’s a single origin of replication3. DNA polymerase III carries out both the initiation and elongation mechanisms, DNA polymerase I carries out DNA repair, gap fillings and removes RNA primers and, DNA gyrase is needed to relieve the strain when DNA is being unwound3. In prokaryotic DNA replication, Okazaki fragments are large, about 1000-2000 nucleotide long and the replication process is very rapid occurring at a rate of…

    with (xl3). prbp3: third dsRBD of protamine binding protein, trbp3: third dsRBD of TAR-RNA binding protein, Dros: a dsRBD from a Drosophila protein of unknown function. DMStau, a type B dsRBD from Drosophila Staufen protein 4.4. Different activities between Xlrbpa and PACT In this work we could show that Xlrbpa inhibits human PKR in Saccharomyces cerevisiae cells and that this inhibition is due to the RNA binding-ability of Xlrbpa. Others have cloned the human homologue of Xlrbpa, PACT from…
