Answer:
The answer is B
Explanation:
I had this question on my test last week
Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.
Answer:
The answer is D.
Explanation:
Out of the options given in the question, the best one for this example is the Positron Emission Tomography (PET Scane) because it is stated that the active regions of the brain contain high concentration of glucose.
The reason is that a substance similar to glucose is used as an indicator in PET scans to show the part of the body where the inspection is required by emitting gamma rays.
I hope this answer helps.
