What Is Protein Synthesis – How Are Proteins Made – Transcription And Translation

Protein synthesis. So, how are proteins built? In this video we are going to go through a very basic look at how this happens. There are two major events that happen during protein synthesis, transcription and translation. Transcription has three phases, initiation, elongation and termination. The initiation phase of transcription occurs in the nucleus of …

Protein Sythesis

Protein Sythesis

Welcome to Protein Synthesis. In this video, you’ll explore what protein synthesis is including the two parts of its process: transcription and translation. Protein synthesis means making protein. Whenever cells want to make any type of protein, they use a process that includes building blocks like amino acids, to build new proteins inside of the …

Nucleic acids – DNA and RNA structure

Nucleic acids – DNA and RNA structure

In this video we will study about nucleic acids. Nucleic acids are basically biopolymers, which are made of monomeric units known as nuclotides. We have two important functions for nucleic acids, that is, they hold our genetic information and they perform a variety of other functions that we will discuss later. We have two important …

Protein synthesis, DNA translation, m-RNA transcription

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 …

Principal components analysis of protein and nucleotide alignments in Jalview

Principal components analysis of protein and nucleotide alignments in Jalview

In this Jalview Online Training video, I will consider how to do principal components analysis on the protein alignments. Principal Components Analysis is an alternative to cluster analysis as a way to visualise groups of similar sequences. To demonstrate this feature, I will import a group of sequences into Jalview that have already been aligned. …

Proteins and Nucleic Acids : Key Biomolecules II

Proteins and Nucleic Acids : Key Biomolecules II

Hi, everyone! Welcome back to BOGObiology! This tutorial is going to cover proteins and nucleic acids. We will discuss their structure their function and where they can be found. Different groups of atoms combine to form biomolecules. When we talked about carbohydrates and lipids, we used carbon hydrogen oxygen and sometimes nitrogen. Now that we’re …
