different amino acids produced during translation in the ribosome‚ then there will be unique proteins created‚ too. This allows there to be more types of proteins in an organism than types of genes in an organism’s genome. Repressor proteins can influence the regulation of protein synthesis by binding to operators (the segments of DNA that act as switches to either allow or prohibit RNA polymerase to create mRNA strands) in an operon. Since repressors block transcription of genes‚ many mRNA strands that

is the copy‚ the working script as it were; now then...one step deeper in the gene pool (oh‚ I have ALWAYS wanted to say that!) - there is an essential enzyme called RNA polymerase that will bind to the DNA strand allowing it unwind (during the transcription phase)‚ thus giving it a base from which to build a template for the copy that ’ll follow. This way‚ a single gene can be copied into hundred‚ thousands...millions...eh‚ you get the idea. Works sort of like PK-Unzip‚ just WAY more efficient (and

it was not the witches who were recruited by the devil to harm mankind‚ but that the very belief that witches existed at all was a harmful diabolical invention” (pg. 280).

DNA is synthesized from DNA‚ and RNA from RNA). RNA can be made or transcribed from DNA. It is called transcription since the same type of "language" is used in DNA and RNA -- i.e. nucleic acids. In some cases RNA may be used to make DNA (i.e. "reverse transcription") using a particular enzyme called reverse transcriptase. Protein is synthesized from RNA by translation. It is called translation‚ because essentially a different "language" is used -- i.e. amino acids (instead of nucleic acids). Once

In protein synthesis‚ there are three steps: transcription‚ RNA processing‚ and translation. In transcription‚ the enzyme RNA polymerase unzips doubled stranded DNA‚ and then attaches the corresponding nucleotides to the DNA sequence. Then‚ RNA Processing occurs‚ where the new messenger RNA strand is edited by a spliceosome. The
