<span>The interactions
between the mRNA codons and the tRNA anticodons
codes for a specific amino acid is by, it is the job of the tRNA to
start working after the mRNA has able to have its own complementary copy. The
mRNA will undergo to the nucleus and will move out, in order to go the rrna.
The three nucleotides codes the specific amino acid of the trna. The trna and
the mrna will be matched, it will now release the amino acid in the trna that
wil form a peptide bond. When the mrna is able to be decoded to form an amino
acid, it will now have the ability to break and make proteins in different
structures.</span>
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
<em> B. Master genes do not </em><u><em>determine the organization of the genome</em></u><em>
.</em>
<em> C. </em><u><em>Regulation of cell metabolism</em></u><em> depends of substances as hormones and enzymes.
</em>
<em> D. </em><u><em>The rate of translation</em></u><em> does not depend on the activity of master genes.</em>
Answer:
The transport protein-hormone complexes of lipid soluble proteins can not cross the filtration membrane of glomerulus.
Explanation:
Steroid hormones are water-insoluble (hydrophobic) in nature. Since blood has watery medium, the plasma, the lipid-soluble hormones travel in blood through transport proteins. The transport protein-hormone complexes are too large to cross the filtration membrane of glomerulus. The impermeability of the filtration membrane of glomerulus for protein-hormone complexes increases the half-life of lipid-soluble proteins.
Answer:
The correct answer is option - 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.
Explanation:
Normally the drug that is provided and administrated to the fetal is through the placenta of the mother. The direct delivery of medicine can be dangerous. However, with the advancement of the medical technology direct fetal drug administration is possible and it assists in the rapid uptake of the drug by the fetus.
If the fetus requires a rapid drug effect it can be provided by direct drug delivery. Also when the placental is not working properly and affected by the disease it is recommended to provide the fetus with the drug with the help of direct delivery.
Thus, the correct answer is : 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.
Answer: C- glycolysis, krebs cycle, electron transport chain.
Explanation: Glycolysis is a catabolic reaction that comprises of series of steps that breaks down food to give off energy in a form of ATP. Pyruvate is the product of glycolysis together with two ATP molecules. Pyruvate is further broken down by joining the krebs cycle and finally the electron transport chain that transfer electrons using the redox reaction, to reduce NADH to NAD + H and FADH to FAD, creating the final product i.e ATP, Overall one glucose molecule gives 38 ATP molecules in aerobic respiration.
