Genes are expressed through the process of protein synthesis. This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases...
This tutorial looks at the mutation at the gene level and the harm it may bring. Learn about single nucleotide polymorphisms, temperature-sensitive mutations, indels, trinucleotide repeat expansions, and gene duplication...
Part of the genetic information is devoted to the synthesis of proteins. mRNA, a type of RNA, is produced as a transcript that carries the code for protein synthesis. Read this tutorial for further details...
