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.
Solar eclipses are an accident of nature. They are so spectacular because the Moon and the Sun appear almost the same size. In reality the Sun is much further away then the Moon, but much larger. The Moon orbits the Earth once a month, and eclipses happen if it lines up exactly with the Earth and the Sun. Solar eclipses occur at New Moon, when the Moon is between Earth and the Sun. Lunar eclipses occur at Full Moon, when Earth is between the Sun and the Moon. Eclipses do not take place every month because the orbits of the Moon and Earth are tilted at an angle. Most of the time, the line-up is not precise enough for an eclipse. However, there are more eclipses than people are generally aware of:
