Which of the following lists correctly summarizes the main functions of proteins in the human body? a. Primary energy source, control center providing insulation, enzyme production, and signaling

b. Hormone production, primary energy source, antibody development, and control of metabolic functions

c. Providing insulation, powering movement, providing defense, and storage of genetic code

d. Powering movement, structural support, hormone production, and antibody and enzyme production

The list which correctly summarizes the main functions of proteins in the human body is:

c.powering movement, structural support, hormone production, antibody and enzyme production.

Skeletal muscles are responsible for movement and those muscles are made of protein.

protocol for imps extraction focusing on membrane protein extraction, solubilisation, and purification.

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.
