What is Hypothalamus? Definition of Hypothalamus The hypothalamus is a small but crucial part of the vertebrate brain located beneath the thalamus. It regulates various physiological functions, including body temperature, hunger, thirst, and circadian rhythms, by linking the nervous system to the endocrine system through the pituitary gland. Additionally, it plays a role in controlling … Read more
What is Synapse? Definition of Synapse A synapse is a junction between two neurons or between a neuron and an effector cell, such as a muscle cell, that allows for the transmission of electrical or chemical signals. It consists of a presynaptic terminal, a synaptic cleft, and a postsynaptic terminal, facilitating communication within the nervous … Read more
What is Neuron? Definition of Neuron A neuron is a specialized cell in the nervous system that receives, processes, and transmits information through electrical and chemical signals. How Do Neurons Work? Neurons communicate through a combination of electrical impulses and chemical signals, ensuring efficient information transfer throughout the body. By facilitating the rapid transmission of … Read more
What is Nervous System? Definition of Nervous System The nervous system is a complex network of cells and tissues that coordinates and regulates the activities of an organism by transmitting electrical signals between different parts of the body. Cells of the Nervous System Neurones Glial Cells Astrocytes Oligodendrocytes Microglia Ependymal cells Nervous System Structure and … Read more
What is Recombinant DNA Technology? Definitions of Recombinant DNA Technology Recombinant DNA technology is a method used to manipulate and combine DNA from different sources to create new genetic combinations. It involves inserting genes from one organism into the DNA of another, allowing for the production of specific proteins or traits not naturally found in … Read more
Tissue Culture is the term used to describe the process of removing tissues, cells or organs from either a plant or animal and their subsequent transfer into an artificial environment that encourages development.
What are Silent mutations? Definition of Silent mutations Silent mutations are genetic changes in the DNA sequence that do not alter the amino acid sequence of a protein, resulting in no effect on the protein’s function or the organism’s phenotype. Cause of Silent Mutation Silent mutations are genetic changes that do not alter the final … Read more
What is Linkage? Definition of Genetic Linkage Genetic linkage is the tendency for genes located on the same chromosome to be inherited together due to their physical proximity. Exploring Terms Related to Genetic Linkage Characteristic of Linked Genes Linked genes are genes that are located close together on the same chromosome and tend to be … Read more
Epistasis is the interplay between genes that influence the character. Genes may mask one to the point that one gene is thought to be “dominant” or they can be combined to create a new characteristic. It’s the relation between two genes that could be the basis for a particular phenotype of certain characteristics. Each locus has two alleles that define the phenotypes. They may affect each other in a manner that regardless of the particular allele of one gene it is recessive another dominant variant of. A different expression for epistasis requires a ratio chart, or table.
What is Gene Interactions? Definition of Gene Interactions Gene interactions refer to the relationships between multiple genes where the expression of one gene can influence, or be influenced by, the expression of another gene, collectively determining specific phenotypic traits in an organism. Types of Gene Interaction Gene interactions can be categorized into two primary types: … Read more
