Which of the following formulas is most likely to be a protein molecule?

c6h12o6
c12h22o11
c685h1068n196o211s 5

C685H1068N196O211S 5

Explanation:

Proteins are one of the most important biomolecule that acts as a building block of an organism's body. Proteins contain an amino group, a carboxylic group, a single hydrogen and R- group. R is the chain of hydrocarbon molecule.

Proteins are macromolecules that contains large number of molecules. The molecule C685H1068N196O211S5 acts as a protein because it contains large number of molecules and has an amino, carboxylic group and hydrocarbon chain.

Thus, the correct answer is option (3).

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
