What is the product of the psbc gene? what is its function?

1 answer:

6 0

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.

In which type of reproduction can cells divide through the process of mitosis ?

Aleks04 [339]

<span>Mitosis is carried out for growth and development processes. The cell divide and multiply for growing and removing the worn out cells/damaged cells. Two identical daughter cells are formed in mitosis. Errors in the same may cause genetic disorders, Sex cells divide by the process of meiosis. </span>

Receptors for acetylcholine are located on the

elena-s [515]

Answer:

plasma membrane of the target cell

Explanation:

There are two main types of acetylcholine (ACh)receptors:

muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
nicotinic ACh receptors (nicotin is agonist) which are ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).

Extensive research along the Gulf Shore has uncovered a rise in cancer rates directly linked to consumption of seafood contamina

xeze [42]

The correct answer is option (B) It supports the anti-drilling argument.

Deepwater drilling refers to the process of drilling holes in the deep sea, below the seabeds for the purpose of mining petroleum compounds. Deepwater horizon blowout was an explosion causing a huge oil offshore oilspill in the Gulf of Mexico, making it the largest accidental marine oil spill disaster in the world. It has a numerous negative effects on the marine life.

The toxic oil and its compounds released into the water during the deepwater horizon blowout has contaminated the water and affected the marine life including the phytoplanktons, zooplanktons, invertebrates, fishes and other mammals of the sea. Highly toxic chemical components such as benzene and polycyclic aromatic compounds have even caused DNA damage and mutations in the marine life. Apart from their mortality, it has also been responsible for reduced growth, diseases, impaired reproduction in the sea fauna. Thus, ingestion of such contaminated seafood grown in contaminated water can be held responsible for the rise in cancer rates. Thereby supporting the anti-drilling arguement.
