The correct answer is option (D) store and release neurotransmitters.
The function of synaptic vesicles inside the axon terminals is to store and release the neurotransmitters. A synapse refers to the junction between the two neurons which transmit the nerve impulses by the diffusion of a neurotransmitter. Synaptic vesicles ar important for the transmission or the conduction of the nerve impulses as they store and release the neurotransmitters.
These neurotransmitters are the chemicals that transmit an impulse between two neurons or a neuromuscular junction. A neurotransmitter is released by the synaptic vesicle of one neuron into a region between the two neurons called the synapatic cleft. From here, it reaches the neurtransmitter receptors present on the target neuron, thus conducting the impulse. Examples of neurotransmitters include the epinephrine, histamine, acetylcholine and others.
Answer:
The provided events can be classified as:
Initiation
- In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
- In E. coli, mRNA binds to the 30S ribosomal subunit.
Elongation
- In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
- Initiator tRNA enters the P site.
- In E. coli, EF-Tu hydrolyzes.
- Translocation occurs
Termination
- The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site
Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).
It is divided into three stages:
Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.
Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next codon.
Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.
Answer: Shine a bright light on one side of the ball.
Explanation: The light replicates the Sun shining light on one side of the Earth.
Prothallus represents a gametophyte in the life cycle of fern.
A prothallium, or prothallus<span> (from Latin pro = forwards and Greek θαλλος (thallos) = twig) is usually the gametophyte stage in the life of a fern or other pteridophyte. Occasionally the term is also used to describe the young gametophyte of a liverwort or peat moss as well.
so the answer should be prothallus</span>
