Question: If is possible to synthesize proteins in vitro (in a test tube) without the use of living cells. If starting from a mature mRNA transcript, which of the following components would not be needed to do this?
(a) Adenine Molecules
(b) Amino Acids
(c) tRNAs
(d) Ribosomes
The correct answer is (a) Adenine Molecules.
Explanation:
Transcription can be explain as transfer of genetic information from DNA to RNA. During transcription, mRNA is produced as copy of gene to allow the genetic information go out of nucleus to form protein. Adenine molecules would not be needed for this process. Actually, It is formed when adenine is attached to a ribose ring and one of the bases used in forming nucleotides of the DNA and RNA not in transcription.

Answer:
The correct answer is B An enzyme binds to the substrate at enzyme"s substrate site.
Explanation:
Enzyme is proteinecious in nature and act as homogenous biological catalyst.Enzyme contain an active site or substrate binding site to which specific substrate binds.
The active site of an enzyme contain many amino acids such as cystein,histidine,aspartic acid ,glutamic acid.These amino acids contain functional groups such as -SH group,-OH group,-COOH group. These functional group facilitate the binding of substrate to the active site of an zymes.
"During inhalation, the diaphragm contracts downward, and rib muscles pull upward, causing air to fill the lungs. (This increases the volume of the thoracic cavity and decreases pressure in the lungs — the air will flow from the higher pressure environment to lower pressure area in the lungs.) "
"When you pull down on the diaphragm, you increase the volume of the bell jar, thus lowering the pressure. Air is then forced into the “lungs” from outside, lowering the volume in the bell jar (and stretching the balloons) until the pressures inside and outside the bell jar are equal."
