GENE- Antimony explains

What is gene?

Hmm. Sounds weird.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes.

Every person has two copies of each gene😮, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.🤔

Scientists keep track of genes by giving them unique names. Because gene names can be long, genes are also assigned symbols, which are short combinations of letters (and sometimes numbers) that represent an abbreviated version of the gene name. For example, a gene on chromosome 7 that has been associated with cystic fibrosis is called the cystic fibrosis transmembrane conductance regulator; its symbol is CFTR.

Genes are made up of DNA. 🤐Each chromosome contains many genes.

I hope you have learnt something new today

(0.6)HISTORY OF ATOM- Antimony explains

Ohh. Now in 1920 this Scientist;Erwin Schrödinger vex and scatter everywhere with his new hypothesis.🤓 Erwin Schrödinger was a revolutionary physicist who used Heisenberg’s uncertainty principle to come up with the atomic model that we still use today. SCHRÖDINGER’S ATOMIC MODEL (AKA THE CLOUD MODEL) After doing a lot of work he concluded these salient points am going to alight now. They include: 1. An electron does not travel in an exact orbit😗 2. We can predict where it will probably be😙 3. We cannot say for certain where it is, but only where it ought to be.😚 4. The type of probability orbit is dependent on the energy level described by Bohr☺ Let's now summarize what we know of atoms. The smallest part of an element is called an atom Each atom (of an element) is different in structure from other atoms (of other elements) An atom can be divided in smaller subatomic particles: Protons, Electrons and Neutrons The nucleus is the centre of an atom. It contains protons and neut

CELLS-Antimony explains😊

What is cell? Maybe you have heard of that word before..🤔 Cell is the basic building blocks of all living things.😋 intresting right?. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.😊😐 Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell. Human cells contain the following major parts which am going to list in alphabetical order: Cytoplasm Within cells, the cytoplasm is made up of a jelly-like fluid (called the cytosol) and other structures that surround the nucleus. Cytoskeleton The cytoskeleton is a network of long fibers that make up the cell’s structural framework. The cytoskeleton has several critical functions, including determining cell s

WHY THE SKY IS BLUE-Antimony explains

Antimony-Explains Why is the sky blue? It’s a common misconception that the sky is blue because it reflects the blue of the seas and oceans. A lot of myths have also been told about our blue sky😉. That is why Antimony is here for you. To debunk those non relevant ideas.😊 As for the seas reflection it is very wrong. In fact, it’s the Earth’s atmosphere, and a process known as 'scattering', that causes our skies to be blue. So what is this scattering. As white light passes through our atmosphere, tiny air molecules cause it to ‘scatter’. The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day. When the Sun is low in the sky during sunrise and sunset, the light has to travel further through the Earth’s atmosphere. We don’t see t
