Which of the following options best depicts the flow of information when a gene directs the synthesis
of a cellular component (transcription and translation)?
a. dna → mrna → protein
b. mrna dna → protein
c. protein → mrna → dna
d. mrna → protein > dna
e. dna → protein mrna

The flow of DNA → mRNA → protein depicts the flow of information when a gene directs the synthesis of a cellular component.

Explanation:

Genetic information needs to flow in a specific pattern in order a gene to transform into a component like protein. This transformation takes place through the processes of transcription inside the nucleus and translation in the ribosomes. So the pathway: DNA → mRNA → protein will be correct flow of information for protein synthesis from DNA code. The mRNA or the messenger RNA encodes the genetic information or the chemical blueprint of the particular protein to be synthesized. This flow represents the central dogma of genetic information pathway or flow, which is; DNA encodes the RNA and the RNA encodes the Protein

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
