When a butter is treated with fatty acid desaturase,
the hydrogen atom will be removed and form a carbon double bond, which allow the
membrane to become more fluid. When temperatures change, a phase transition
occurs. If the temperature decrease, the membrane gels becomes solid which then
results to cracks and the imbedded proteins cannot partake in conformational
changes, thus it is important to maintain membrane fluidity.

Answer:
C. mRNA
Explanation:
Hello,
In this case, we may remember that when DNA is undergoing transcription a specific sequence is copied via the RNA polymerase in order to produce the messenger RNA which is subsequently used as the starting material of translation for the protein synthesis as shown on the attached picture. Thereby, answer is C. mRNA, since the transcription process produces it and then, for the translation process, it contains the codons which promote the formation of polypeptides (proteins) via the connection of the anti-codons contained in the tRNA which also provide the amino acids for the polypeptides formation.
Regards.
