What's a genome? And why is it important?

•A genome is all the DNA in an organism, including its genes.
•Genes carry information for making all the proteins required by all organisms. These proteins determine, among other things, how the organism looks, how well its body metabolizes food or fights infection, and sometimes even how it behaves.
•DNA is made up of four similar chemicals (called bases and abbreviated A, T, C, and G) that are repeated millions or billions of times throughout a genome. The human genome, for example, has 3 billion pairs of bases.
•The particular order of As, Ts, Cs, and Gs is extremely important. The order underlies all of life's diversity, even dictating whether an organism is human or another species such as yeast, rice, or fruit fly, all of which have their own genomes and are themselves the focus of genome projects. Because all organisms are related through similarities in DNA sequences, insights gained from nonhuman genomes often lead to new knowledge about human biology.

A gene is a section of DNA that tells how to make one kind of protein.

The bases in that section of DNA tell exactly which amino acids to put together to make the protein. The tell the kind of amino acids and they tell exactly what order to put the amino acids in.

PROTEIN SYNTHESIS This technique may well be divided into 2 aspects: a million. Transcription earlier the synthesis of a protein starts, the corresponding RNA molecule is produced by potential of RNA transcription. One strand of the DNA double helix is used as a template by potential of the RNA polymerase to synthesize a messenger RNA (mRNA). This mRNA migrates from the nucleus to the cytoplasm. in this step, mRNA is going by using categories of maturation including 1 called splicing whilst the non-coding sequences are eradicated. The coding mRNA sequence may well be defined as a unit of three nucleotides called a codon. 2. Translation The ribosome binds to the mRNA on the commencing up codon (AUG) this is known in basic terms by potential of the initiator tRNA. The ribosome proceeds to the elongation part of protein synthesis. in this degree, complexes, composed of an amino acid appropriate to tRNA, sequentially bind to the suited codon in mRNA by potential of forming complementary base pairs with the tRNA anticodon. The ribosome strikes from codon to codon alongside the mRNA. Amino acids are further one by potential of one, translated into polypeptidic sequences dictated by potential of DNA and represented by potential of mRNA. on the top, a launch ingredient binds to the give up codon, terminating translation and liberating the comprehensive polypeptide from the ribosome.
