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.
Helicase breaks hydrogen bonds of the DNA helix. Therefore it “unzips” the DNA helix and separates the strands for free complementary RNA strands which use the strands as a template during replication.
2010: the census of marine life is completed.
2011: Mariana Trench exploration
2012: first solo dive into the Mariana Trench. hope this helps. :)
Answer:
It would be difficult to recreate the exact conditions of the chemical release elsewhere.
Explanation:
Answer:
Krill
Explanation:
Based on the information provided within the question it can be said that the the Crabeater Seal's main source of food are Krill. These are a type of shrimp that can be found in cold water such as Antarctica. Despite the misleading name Crabeater Seal' do not eat crabs seeing as since the are no crabs in Antartica.
