cDNA library: cDNA library: Process of construction of cDNA library, Advantages, and Disadvantages cDNA library: A cDNA is a DNA copy that is generated from messenger RNA (mRNA) with the help of the enzyme reverse transcriptase. A set of cDNA fragments, each of which has been cloned into a separate vector molecule constituting part of … Read more
Define Epistasis- Classes, Types, Examples, Significance Epistasis is the interaction between two non-allelic genes in which the phenotypic expression of one gene is masked or repressed by the expression of one or more other genes. Mendelian and his collaborators previously assumed that the traits were determined by the expression of a single gene with two … Read more
Gene Prediction- Importance and Methods One of the main topics in bioinformatics is the prediction of genes using computer-assisted methods for the localization of protein-coding regions. Predicting genes essentially means locating genes throughout a genome. Also called gene discovery, it refers to the process of identifying regions of genomic DNA that code for genes. These … Read more
Definition of Pseudocoelomate A pseudocoelomate is an organism with a body cavity that is not derived from the mesoderm, as in a true coelom or body cavity. A pseudocoelomate is also known as a blastocoelomate because the body cavity is derived from the blastocoel of the cavity inside the embryo. A true coelom is lined … Read more
Sanger sequencing method In a previous article on the Human Genome Project, we talked about the feat of obtaining the complete sequence of our genome, as well as its applications. For this, it was necessary to determine the order of the nucleotides that make up DNA , which required a considerable effort on the part of several universities and research … Read more
What is CRISPR, the technique that will change genetic manipulation? What is CRISPR? These are DNA sequences that contain a multitude of palindromic segments, that is, sequences that are read in the same way in both directions of the DNA strand. These palindromic segments are divided by spacer sequences and there is also a “leader” sequence. The set of the palindromic, … Read more
What is a dominant gene and a recessive gene? The transmission of characters between parental organisms and their offspring is a complex and fascinating subject. The first person to carry out an analytical investigation of this matter was the monk Gregor Mendel in the 19th century, without knowing what a gene was. Mendel became famous for his … Read more
Human Genome Project: what is it and what applications does it have? The first genetic studies date back to the 19th century, long before we knew what genes were. By growing peas ( Pisum sativum ) with different characteristics, the Augustinian monk Gregor Mendel was able to elaborate on the so-called laws of inheritance, which describe how some characters are … Read more

Define coenzyme and give an Example Define coenzyme and give an example coenzyme (often also a coenzyme) is a non-proteinaceous component of enzymes. It helps enzymes to catalyze (accelerate) reactions. This is possible because the coenzyme binds to the enzyme for a short time. If it is a non-covalent (not fixed) bond, you call the coenzyme a cosubstrate . When a coenzyme binds covalently (tightly) to … Read more
