Earth<span> can be divided into three main </span>layers<span>: the core, the mantle and the crust
Your answer would be, Core.
(Could also be called inner core)
Think of it as a watermelon, you have the crust, which is the green part, the mantle which is the whitish green part and the red which is the core.
Hope this helps.
In case you didn't get any of that, the answer is Core</span>
The phases go prophase, metaphase, anaphase, and telophase starting with interphase. But the first stage would be Interphase.
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.
