A set of codons could be started to read from any place of the base sequence, which makes a set of codons in a DNA strand possible to create six types of proteins; as an example if the sequence is ATGCTGATTCGA, then the first codon could be any of ATG, TGC, and GCT.
A lunar eclipse and a solar eclipse refer to events involving three celestial bodies: the Sun (solar), the moon (lunar), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun. An eclipse can be total, partial, or annular.
Not to be confused with Solar eclipse. A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in syzygy) exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can occur only the night of a full moon.
