How does DNA work? Tutorial video

How does DNA work? Tutorial video | Science | guardian.co.uk Biology teacher Ceri Evans gives a tutorial on DNA and the genetic code – specifically the one gene/one protein hypothesis, which is part of the GCSE biology curriculum. To make this difficult, abstract concept more concrete, he starts by getting the students to transcribe an analogous colour code. He goes on to explain the DNA triplet code – which specifies the sequence of amino acids in a protein – mRNA transcription and…

The primary structure refers to amino acid linear sequence of the polypeptide chain. The primary structure is held together by covalent bonds such as peptide bonds. The primary structure of a protein is determined by the gene corresponding to the protein. A specific sequence of nucleotides in DNA is transcribed into mRNA, which is read by the ribosome in a process called translation.

TJ. In molecular biology and genetics, translation is the process in which cellular ribosomes create proteins. In translation, messenger RNA (mRNA)—produced by transcription from DNA—is decoded by a ribosome to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell. The ribosome facilitates decoding by inducing the binding of complementary tRNA anticodon sequences to mRNA codons. The tRNAs carry…

Protein Synthesis and Translation Activity

In this lab, you will be creating a 'mystery organism'. You must determine which proteins will be made to produce your mystery organism. You will be simulating the process of protein synthesis to determine the traits this organism will inherit. Your mystery organism belongs to the Animal Kingdom. If is made up of 6 different genes (A, B, C, D, E, and F). Each of these genes is responsible for a certain trait.
