RNA reads and translates the DNA code.
Erosion creates sand dunes, beaches, and deltas. The process of erosion either by chemical or physical means causes the formation of many types of land forms like the one mentioned a while ago. Without erosion the life cycle of Earth will not be a continuous one and many organisms will not survive.
The patient is receiving succinylcholine or commercially called anectine.
Succinylcholine is a medication often used in the context of general anaesthesia and its main effect is general paralysis. The drug's mechanism of action includes the inhibition of the acetylcholine's action on skeletal muscles. This inhibition is caused by the binding of the drug on the nicotinic acetylcholine receptor and the depolarization of the muscle cell.
I'm pretty sure the answer is C, there are 4 nitrogenous bases involved.
<span>1) Adenine
2) Guanine
3) Thymine
4) Cytosine</span>
DNA is forms a double helix shape/strand. The rule of base pairing is pretty much something that you just need to know by heart. A (adenine), T (Thymine), G (Guanine), and C (Cytosine) and the 4 bases that make up DNA.
***** The most important part is to know that A always pairs with T and G always pairs with C *****
So, the double helix strand of DNA is made up of two strands - kind of like a ladder - one strand is the original, while the other is a replicate of the original strand that is formed through different steps of polymerase reaction etc.
So, for example, let's say strand 1 has this code: ATGCTAGCTGATCG (I made this up, probably doesn't code for anything). But, knowing this, what will it's replicate of second strand look like?
Original strand: ATGCTAGCTGATCG
Replicate Strand: TACGATCGACTAGC
So, you can see from the above example that to form the replicate strand, you just insert the base that pairs with the one from the original strand. A-T and G-C!
Hope that helped!
