Genome Editing And CRISPR-Cas9 Technology Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism’s DNA, leading to changes in physical traits, like eye color, and disease risk. How does Gene-editing work? The CRISPR-Cas9 gene-editing tool thus has two components. They are: Application of Gene-Editing

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Genes carry information for particular characteristics, such as ear shape or eye colour. Different sets of genes carry information for different characteristics. There are many genes in a chromosome. Some genes act as instructions to make molecules called proteins. However,

Introduction about DNA DNA is an abbreviation of deoxyribonucleic acid. It is an organic chemical of complex molecular structure that is found in all prokaryotic and eukaryotic cells and in many viruses. DNA codes genetic information for the transmission of inherited traits. There is DNA in the nucleus of every cell. DNA carries genetic information. It has all the instructions that a living organism

Diseases Caused By Microorganisms Microorganisms or microbes are microscopic organisms that exist as unicellular, multicellular, or cell clusters. They can be divided into six major types: bacteria, archaea, fungi, protozoa, algae, and viruses. While some microbes play an important part in our daily lives by keeping us healthy, others are nothing but disease-causing microbes and

What is a Chromosome? Chromosomes are microscopic thread-like structures located inside the nucleus of animal and plant cells that carries hereditary information in the form of genes. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature

Following are the important differences between DNA and RNA: DNA (Deoxyribonucleic acid) RNA (Ribonucleic acid) DNA replicates and stores genetic information. It is a blueprint for all genetic information contained within an organism RNA converts the genetic information contained within DNA to a format used to build proteins, and then moves it to ribosomal protein
