Answer:
Please find the explanation below
Explanation:
Transcription is the first process that occurs in protein synthesis. It involves the use of the stored information in the DNA molecule to synthesize a mRNA molecule.
Transcription, which occurs in the nucleus of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA polymerase. RNA polymerase binds to the double-stranded DNA and begins to unwind it (Initiation). This unwinding causes the nucleotide bases to be exposed in order for the RNA polymerase enzyme to read.
The enzyme reads the bases of the DNA and begins to synthesize RNA nucleotides using the complementary base pairing rule (Elongation) i.e. Adenine base paired with Uracil base (RNA), and Guanine paired with Cytosine etc.
The single-stranded mRNA is released at the end of the transcription process (termination). This is basically what occurs in transcription.
Answer:
Hydrogen bonding.
Explanation:
Hydrogen bonding is basically the force which holds the molecules of water together. It is an extremely strong force and is responsible for higher boiling point of water. Hydrogen bonding occurs due to electronegativity difference between Oxygen and Hydrogen atoms. Hydrogen atom develops partial negative charge while Oxygen develops partial positive charge. Therefore, Oxygen atom of one molecule attracts the hydrogen of other molecule and this goes one. This way extremely strong bonding develops that holds water molecules together.

Let's talk about coagulation to help you drop these labels:
Coagulation involves a cascade of enzymatic reactions involving coagulation factors, several of which are serine-active proteases at the active site and subjected to activations and inhibitions. The final step is the transformation of soluble fibrinogen into fibrin filaments that encircle circulating cells in their meshes. The factors of coagulation are designated by numbers from I to XIII. With the exception of the factor XIII which intervenes in the last stage of the coagulation.
Coagulation involves two pathways, one intrinsic, the other extrinsic, leading to a common final pathway.
<u>
The intrinsic pathway</u> involves the factors present in the circulation (which are factor XII, IX, and XI, they are triggered in that order. and also cofactor VIII which helps to activate the factor IX).
<u>The extrinsic pathway</u> involves the tissue factors not normally present in the circulation but which are released during a vascular lesion (thromboplastin (factor III) and factor VII).
Factor Xa is the meeting point of the intrinsic and extrinsic pathways. The Xa, Va, Ca2 + set and a platelet phospholipid are sometimes called prothrombinase (or prothrombin activator).
