Genetic code
(Science: molecular biology) relationship between the sequence of bases in nucleic acid and the order of amino acids in the polypeptide synthesised from it. A sequence of three nucleic acid bases (a triplet) acts as a codeword (codon) for one amino acid.
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...
This tutorial presents the benefits and the possible adverse eventualities of genetic engineering. Know more about this topic in this tutorial to be able to articulate the advantages and disadvantages of artificially manipulating genes...
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...
DNA is a double helix structure comprised of nucleotides. A nucleotide, in turn, is made up of phosphate molecule, deoxyribose, and a nitrogenous base. Know the fundamental structure of DNA and the process of DNA replication in this tutorial...
Plants are characterized by having alternation of generations in their life cycles. This tutorial is a review of plant mitosis, meiosis, and alternation of generations. ..
