Introduction Skeletal muscles are the most abundant tissue forum in the human body. More than 40% or our body is made up of skeletal muscles. These are the voluntary muscles that are under the control of the somatic nervous system. Most of the skeletal muscles are attached to bones via specialized connective tissues. In this …
Introduction to Prokaryotic vs Eukaryotic Living organisms are divided into two groups based on the primary differences in their cellular structures; prokaryotes and eukaryotes. It has been believed that prokaryotes were the first organisms to appear on Earth. The rest of the higher organisms evolved from these simple prokaryotic organisms. They differ in terms of …
Introduction Ribonucleic acid or RNAs are the working copies of DNA. The information present in DNA is expressed in the form of these working copies. Three major types of RNA are found in all the living cells; messenger RNA, ribosomal RNA, and transfer RNA. The messenger RNA (mRNA) carries the message of DNA from the …
Introduction Glucose is the main source of energy for almost all the cells in our body. A large amount of energy is released upon the oxidative metabolism of glucose in living cells. This energy is used to phosphorylate ADP to ATP, the energy currency of the cell. Glucose can also be stored in living bodies …
Introduction The genetic material in living organisms is present in the form of DNA. This DNA does not lie within the cell in the form of threads. Rather, DNA in eukaryotes is organized into higher structures to keep it compact so that it can fit into the nucleus. The DNA in eukaryotes is wound around …
Introduction Conservation of the environment is a set of methods and practices which are observed to preserve the environment, its inhabitants, and the resources it provides. There is a need for conservation of the environment as there is continuous inflation of population, pollution, and consumption of resources. We must learn to protect and conserve nature …
Introduction The tern ‘Epigenetics’ is used for the changes in DNA that can alter phenotype or trait without altering the nucleotide sequence present in the DNA. These are the heritable changes that can affect gene expression. Any change in gene expression will lead to a change in the phenotype of that gene or the trait …
Introduction The genetic information is present in all the organisms in the form of DNA. This DNA is present in the nuclei of eukaryotic cells and contains the information for all the traits expressed by the cell. The genetic material controls al the traits of a cell by guiding and controlling the synthesis of proteins. …
Introduction to Gene Mutations A gene is a part of DNA that codes for the synthesis of one protein. The entire DNA is made up of thousands of genes that directly control all the functions of a cell via protein synthesis. The sequence of nucleotides in a gene determines the sequence of amino acids in …
The Meselson-Stahl experiment was a groundbreaking scientific study conducted in 1958 by Matthew Meselson and Franklin Stahl. This experiment provided strong evidence supporting the theory of semi-conservative DNA replication, which was proposed by James Watson and Francis Crick. Read more about an Introduction to DNA Replication Discovery and History After the brilliant work of describing …
