(a) Describe the process by which cells produce the FGF5 pre-mRNA , and include the location

Svetlanka [38]

Answer:

Explanation:

mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.

FGF5 is a gene that is encoded in the DNA.

In order for high force crossbridges to form in contracting skeletal muscle, calcium must a. bind to calmodulin to phosphorylate

Maksim231197 [3]

Answer:

e. bind to troponin which moves the tropomyosin.

Explanation:

Troponin (Tn) is a protein complex composed of three different proteins: troponin C (TnC), troponin I (TnI), and troponin T (TnT). This complex is found both in skeletal muscles and cardiac muscles, where TnC attaches calcium ions through four and three calcium ion-binding sites, respectively. When a muscle is relaxed, Tn attaches to tropomyosin to prevent muscle contraction. During muscle contraction, calcium channels open and cytosolic calcium ions bind to TnC, thereby Tn changes its conformation and moves the tropomyosin. This process relieves the inhibition of the interaction between actin and myosin filaments, which makes muscle contraction possible.
