Answer:
mRNA: AUG CAA AAU GCG AUC UGA
Amino acids: Methionine, Glutamine, Asparagine, Arginine, Isoleucine, Stop
Explanation: for amino acids just make the usual pairs, so G-C and T-A but T is U in mRNA. For the amino acids, just read off the table starting with the first letter of the triplet in the centre then reading outwards for the second and third.
Hope this helped :)
Answer:A. The release of calcium ions causes myosin and actin to attach to each other.
The contraction of skeletal muscles takes place by induction of a nerve impulse, which produces a movement and the interaction of the filaments containing proteins named as actin and myosin. This interaction of filaments is regulated by proteins called tropomyosin and troponin present on the actin filaments. The motor nerve causes the depolarization of the muscle membrane sarcolemma. This triggers the sarcoplasmic reticulum to release calcium ions. This calcium binds to troponin and thus allows the tropomyosine strand on the actin filament to displace so that the part of the actin where myosine head needs to be attached remain uncovered. Binding of the actin myosine filament results in contraction.
Hence, the release of calcium ions causes myosin and actin to attach to each other causes muscle contraction.
