DNA stands for deoxyribonucleic acid and is a molecule with the instructions for cells to develop and reproduce. It is present in the nucleus of every cell in humans and most living organisms. DNA:DNA is the molecule that contains the information about how to build an organism with most ...
What is DNA sequencing technology? What is DNA helicase? What is mRNA splicing? What is a retrovirus? Which type of DNA virus has a single-stranded genome? What is a promoter in DNA replication? What RNA virus replicates in the nucleus?
One such case is DNA repair at the natural ends of linear chromosomes, known as telomeres, which can lead to chromosome-end fusions. Here, we review data obtained over the past decade and discuss the mechanisms that protect mammalian chromosome ends from the DNA damage response. We also ...
Anyone who reads the paper or any of the scientific magazines (Scientific American, Discover, Popular Science) is aware that genes are BIG news these days. Here are some of the terms you commonly see: Biotechnology Gene splicing Human genome Genetic engineering Recombinant DNA Genetic diseases Gene...
DNA of adenine, guanine and cytosine, but it has the base or uracil instead of the thymine that is in DNA. The structure of DNA and RNA are vastly different, as DNA is a double stranded helix and RNA is single-stranded. RNA chains can fold into a wide variety of many shapes in the...
DNA sequencesevolution distanceevolution treenucleotide substitution modelTraditionally, specific DNA recognition is thought to rely on static contacts with the bases or phosphates. Recent results, however, indicate that residues far outside the binding context can crucially influence selectivity or binding ...
This is done by gel electrophoresis, membrane purification, or bead selection [9].Applications of RNA sequencingRNA-seq can be performed on samples without having prior information about the genome, providing high levels of details about gene expression, alternative splicing, and other transcriptional ...
What is a gene? What is the complementary RNA sequence of the DNA sequence GAACCGT? Fill in the blank: Genes that are located close to each other on the same chromosome are referred to as ___ genes. DNA sequences that are very similar in related species or genes are called ___. Wha...
A ribozyme is a molecule of ribonucleic acid that has the ability to act as a catalyst in a chemical reaction. The way a ribozyme...
Used extensively in molecular biology for gene splicing. Endonucleases create precise cuts for gene insertion. 4 Exonuclease Can act on both single-stranded and double-stranded DNA. Exonuclease III acts on double-stranded DNA. 4 Endonuclease Endonucleases are enzymes that cleave the phosphodiester bond...
