The structure of the rye chloroplast DNA, which contains psbC gene coding for 43-kDa chlorophyll(a)-binding subunit of photosystem II, is determined. The sequence of trnS (UGA) gene encoding tRNA Ser is located at a distance of 140 bp downstream from the stop codon of psbC gene on the opposite DNA strand. The 5'-terminal part of psbC gene, like in other plants, overlaps by 50 bp the 3'-terminal region of psbD gene coding for D2 protein of photosystem II. The amino acid sequence of the psbC gene product reveals common features with the structure of the psbB gene product (CPa-1 protein). The structural similarity of these two proteins seems to reflect their similar functions.

Greater portions of the beach begin to appear during ebbing tides, until the maximum amount of beach is visible at low tide. They usually happens twice in a day. Beaches results from wave action by which waves or currents move sand or other loose sediments of which the beach is made as these particles are held in suspension.
Answer:
the sun
Explanation:
The typical lunar eclipse happens when the Sun, Earth and moon are all aligned 180 degrees apart from each other in the sky. When this happens, the Earth casts a shadow onto the moon, so the Sun should not be visible at all if you can still see the moon.
