Protein Synthesis, DNA Translation, M-RNA Transcription

This animation demonstrates how the digital information encoded within DNA is used to direct protein synthesis. This is a DNA double-helix containing the digital code which directs the cell in all aspects of operation. And here we see a protein complex called an RNA polymerase travelling down the DNA strand. As it moves down the […]

Nucleic Acids, Carbohydrates, and Lipids

Hi all Dr. Clark here again with another general biology today we’re gonna finish off the biomolecules okay last time we talked about proteins this time we’re gonna try to slam in nucleic acids carbohydrates and lipids all together now nucleic acids is going to be really short because we will spend multiple lectures talking […]

#07 Biochemistry Protein Characterization Lecture for Kevin Ahern’s BB 450/550

Another Monday beckons, another week beckons. One day closer to an exam. Student: Whoo! Kevin Ahern: Yay, huh? One day closer to your opportunity to show me how much you know. That’s good. I hope you had a good weekend. Student: Fantastic. Kevin Ahern: Fantastic? Student: We won. Kevin Ahern: Are we talking about football […]

Introduction to Chemical Biology 128. Lecture 09: RNA part 2

Chromosomes, Genes, and DNA – Overview: From DNA to Protein

To make a protein, a gene’s DNA sequence is transcribed to a strand of RNA. Then the RNA is translated into a chain of amino acids by a ribosome, and a protein is formed. To access a comprehensive array of complete multimedia lessons, as well as the most up-to-date, standards-based curriculum content that’s researched, proven […]

Hershey Chase & Avery Griffiths (Bacterial Transformation)

Hello, bio people. Today we’re going to discuss Griffiths and also Hershey and Chase. Both of these experiments were very important in discovering exactly how genetic material can be passed on from parent to offspring. Griffiths’ experiment happened first in 1928 and so we’re going to discuss that one first. Griffiths’ experiment proved that bacteria […]

Messenger RNA | Wikipedia audio article

Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. The RNA polymerase enzyme transcribes genes into primary transcript mRNA (known as pre-mRNA) leading to processed, mature mRNA. This mature mRNA is […]

Genes, DNA and Chromosomes

Genes DNA and chromosomes are what make you who you are there’s a set of instructions that are given to you by your father and mother these instructions are in yourself and all living organisms are composed of cells are many different types like nerve cells and their selves and skins they all have different […]

Cinelecture 15 – Nucleic Acids – DNA, RNA

no DNA is a very pretty molecules, the DNA double helix but in order to understand its structure which we’ll study in great detail later let’s just look at a single-strand of DNA and examine how the polymer is put together so thats what we’ll do right now. and I just like to point out […]
