The key event in protein synthesis is the formation of bonds …
Protein Synthesis. Molecular events required to generate a. Covers the steps in the process of protein synthesis. Transcription and Translation. VIDEO. What kind of cells are you made of and how do these cells make protein? In this lesson, we will answer these questions through an investigation. Lyrics. Look at what's coming out of the nucleus. Destined for a ribosome, a strand of mRNA. It's got the code, the information, For the protein we'll be making.
Translation is the final step on the way from DNA to protein
How is protein synthesis similar to the catalysis of a reaction by an enzyme? Protein synthesis is a series of chemical reactions in which molecules are brought. Video computer games, virtual labs and activities for learning and reviewing biology. Topics Covered Protein synthesis, transcription, translation, amino acids.
A chain of 50 or more amino acids linked together by peptide bonds
To understand how proteins are made, we have to divide thedecoding process into two steps. DNA only stores the geneticinformation, it isn't involved in the process by which theinformation is used. The first step in protein biosynthesistherefore has to involve transcribing the information inthe DNA structure into a useful form. In a separate step, thisinformation can be translated into a sequence of aminoacids.
Compare with oligopeptide and protein.
The messenger RNA now binds to a ribosome, where the messageis translated into a sequence of amino acids. The amino acidsthat are incorporated into the protein being synthesized arecarried by relatively small RNA molecules known as transferRNA, or tRNA. There are atleast 60 tRNAs, which differ slightly in their structures, ineach cell. At one end of each tRNA is a specific sequence ofthree nucleotides that can bind to the messenger RNA. At theother end is a specific amino acid. Thus, each three-nucleotidesegment of the messenger RNA molecule codes for the incorporationof a particular amino acid. The relationship between thetriplets, or codons, on the mRNA and the amino acids is shown inthe table below.
