Answer:

4. A small ribosomal subunit binds with mRNA;

1. The first tRNA with Met binds to the P site;

3. tRNA comes in to the A site with a new aa;

2. A peptide bond forms between the new amino acid and a polypeptide chain;

5. tRNA in the P site leaves and the tRNA from the A site translocates to the P site.

Explanation:

The first step in translation i.e. protein synthesis is attachment of small ribosomal subunit i.e. 30S subunit with mRNA. Soon after that a tRNA charged with Met binds to the P site of 30 S ribosomal subunit. To this complex further 50S ribosomal subunit binds. Together all these components form '70 S initiation complex". Since this complex already has one amino acid (tRNA with Met) at the P site, in order to create peptide chain another tRNA charged with amino acid must enter the complex. The upcoming tRNA enters the initiation complex at A site. Next, due to the peptidyl transferase activity of large ribosomal subunit i.e. 50S subunit a peptide bond is formed between the amino acid at P site and amino acid at A site. Now since peptide bond has already been formed tRNA at P site is useless so it has to be expelled from the initiation complex via exit site. As soon as this tRNA is expelled, the tRNA which was at A site translocates into P site so that a new tRNA charged with another amino acid could enter the A site for further elongation of peptide chain.

What is the advantage of having the ans neuron that exits the cord synapse onto a second neuron before the target cell?
REY [17]

The advantage of having the autonomic nervous system (ans) neuron that exits the cord synapse onto a second neuron before the target cell shows regulation.

A synapse is in charge of allowing a chemical or electrical signal to travel from one neuron to another or to the intended cell. Synapses are essential for tying together sensory organs, particularly those that track down and send pain or touch inputs to the brain. Chemical and electrical synapses are two different kinds of synapses.

Through the synapse on the second neuron, the autonomic nervous system (ANS) is able to regulate the physiological functions of other systems. This implies that every component of the physiological processes can be separately controlled by the ANS.

How has Linda’s exposure to sun throughout her life contributed to her possible melanoma? (Hint: think about what happens to the
pogonyaev

Answer:

Because of the UV radiations from the sun causes the damage to the DNA of the skin cells causing the formation of pyrimidine dimers and also causing inflammation and immune suppressiosn resulting in the formation of melanoma.

Explanation:

The main cause of skin cancer (melanoma) is too much ultraviolet radiation from the sun or the sunbeds.

The carcinogenic , inflammatory , immunosuppressive and DNA damaging properties of ultraviolet radiations contribute to the initiation , progression and metastasis of primary melanoma.

Melanoma usually occurs due to excessive exposure to the UV radiations in the sunlight resulting in awry in the melanin producing cells (melanocytes) that give color to the skin.

Do turkeys get sleepy from that thing in turkey that makes you sleepy?
VladimirAG [237]

Answer:

Turkey allegedly causes drowsiness because it is packed with a nutrient called tryptophan. Tryptophan is one of 20 naturally occurring amino acids—the building blocks of proteins. Because the body is unable to manufacture tryptophan on its own, it must be obtained from food protein.
