The language of DNA in form of nitrogen bases read in a set of three termed as codons and it is being translated as language of proteins.
First mRNA is read according to the genetic code which can relate the amino acid sequence to proteins. mRNA can be use as the template to assemble in order the chain of amino acid. Translation starts when the mRNA is decoded and the sequence is elongated until creating an amino acid sequence. Once the stop codon is reached, translation will be stopped and ribosome will release the polypeptide.
The genetics of red hair appear to be associated with the melanocortin-1 receptor (MC1R), which is found on chromosome 16. Eighty percent of redheads have an MC1R gene variant.
