Answer: Actually, If it used to live in your mouth and it goes into your stomach, it will die because of your stomach acid. if it it causes an infection (which it shouldn't), you might want to ask your doctor.
The answer is B (400 j) because 10% gets taken off so it would go from 4,000 to 400 then to 40
mRNA codons determine which amino acid will be added to the growing polypeptidic chain. tRNA anticodons pair these codons and add the correct amino acid. <em>The </em><em>dipeptide</em><em> formed will be </em><em>Cysteine-Alanine</em><em>.</em>
------------------------------------------
Let us review a few points,
-
In protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction.
- According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain.
- A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly.
- Each codon represents one amino acid used to build the protein.
- Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid.
- The anticodon is a short sequence of bases that pairs with mRNA codons.
- tRNA adds amino acids following the codons sequence in the mRNA molecule.
- The protein grows from the amino terminus to the carboxy terminus.
- Adenine forms pairs with Uracyl ⇒ A↔U
- Guanine pairs with Cytosine ⇒ C↔G
In the exposed example,
→ mRNA ⇒ codons ⇒ 5'-UGC - GCA-3'
→ tRNA ⇒ anticodons ⇒ ACG CGU
→ proteins ⇒ amino acids ⇒ Cys Ala ⇒ Codon UGC codes for Cysteine
⇒Codon GCA codes for Alanine
So, for the given sequence of mRNA, tRNA anticodons are ACG and CGU. And the added amino acids are <em>Cysteine and Alanine</em>.

Answer:
receptor down-regulation
Explanation:
Downregulation is a control mechanism by which a cell decreases the amount of a cellular component, such as RNA or protein, in response to an external variable. In contrast, a reactive increase of a cellular component is called upregulation. An example of downregulation occurs when insulin binds to its receptor and the complex is endocyted in the cell in response to hormonal signaling.
