welcome to moomoomath in science in this video I’d like to show how to transcribe from DNA to mRNA to tRNA to an amino acid DNA is made up of four bases adenine cytosine guanine and thymine let’s shorten this to a C G and T a always pairs with T and G pairs with […]
MilliporeSigma and Seeding Labs Present: DNA Precipitation Hi, I’m Megan Kelly and today I’m going to show you how to precipitate DNA. This procedure is used to purify or concentrate nucleic acids from an aqueous solution. For this procedure, there are three main components that I’m going to tell you about. The first is salt. […]
Okay, Hussein, take it away. What would you like to discuss? Basically, DNA, what does DNA stand for? Okay, cool. DNA stands for deoxyribonucleic acid. So deoxyribo that’s the D part, nucleic is the N, and Acid is the A. Okay. And what happens if there is a tiny error in your DNA which doesn’t […]
To make a particular protein in the cell the relevant gene is first switched on in the DNA. A working copy of the gene called messenger RNA is made. This copying process is called transcription. Next the information in the messenger RNA is acted upon to produce a protein.
Pretty much everybody has heard about DNA from the telly and it’s really popular for people to get their DNA tested to tell them about things like their ancestry. But hardly anyone is actually seen what DNA actually looks like, so this is a really quick little experiment that you can do at home, using […]
To understand how a working copy of the gene is made, we need to be familiar with the structure of RNA. Unlike DNA, RNA is just a single strand of nucleotide units. In DNA, the sugar is deoxyribose, in RNA, it’s ribose. As for the basis, although three or identical, Adenine, Guanine, and Cytosine, the […]
Hello students. In this presentation, we will learn about RNA silencing / interference. Before understanding RNA silencing, let’s discuss about Central Dogma in brief. According to this concept, genetic information is stored in DNA. When DNA undergoes transcription, we get three types of RNA. But in this discussion, we will focus on mRNA only. This […]
