Rare Super 'Blood Moon' Lunar Eclipse Coming, Last Until 2033 | Video. By | August 31, 2015 10:27am ET. On Sept. 27th, 2015, Earthlings will be treated to a skywathching event not seen seen 1982. The 'Supermoon', which appears up to 14% larger in diameter due to its proximity to Earth, will also turn a reddish hue as a result of the Moon passing directly behind the Earth, into its shadow. Full Moon: Why Does It Happen?

How DNA Encodes for Proteins: 1. Transcription: DNA to mRNA. During transcription, DNA is converted to messenger RNA (mRNA) by an enzyme called RNA polymerase. RNA is a molecule that is chemically similar to DNA, and also contains repeating nucleotide subunits. However, the âbasesâ of RNA differ from those of DNA in that thymine (T) is replaced by uracil (U) in RNA. DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). The conversion of DNA to mRNA occurs when an RNA polymerase makes a complementary mRNA copy of a DNA âtemplateâ sequence. Once the mRNA molecule has been synthesized, specific chemical modifications must be made that enable the mRNA to be translated into protein. 2. Translation: mRNA to protein During translation, mRNA is converted to protein. A group of three mRNA nucleotides encodes for a specific amino acid and is called a codon.
