Codon Codon is a combination of three successive nucleotides in a DNA or RNA strand. All the nucleic acids, DNA and RNA, have nucleotides sequenced as a set of codons. Each nucleotide consists of a nitrogenous base, one of A, C, T/U, or G.
The terms solar eclipse and a lunar eclipse refer to events involving three celestial bodies: the Sun (âsolarâ), the Moon (âlunarâ), and the Earth. A solar eclipse occurs when the Moon lines up precisely in front of the Earth so that the Moon blocks the Sunâs rays and the Moonâs shadow falls upon the Earth.
A Total Lunar Eclipse occurs at night with the Moon entering Earth's shadow, firstly into the penumbra (Earth's outer shadow) where only some of the light is blocked from reaching the Moon - turning the Moon from its familiar white to a subtle shade of white-grey.
