Answer:
GLD-1 is a regulatory protein whose function is to regulate the expression of MES-3.
Explanation:
Since the MES-3 protein itself is not modified but only its quantity is, then it is likely that the GLD-1 protein is only inhibiting MES-3's expression; keeping it at a certain level set by the organisms DNA.
Q1. Muscles are made of muscle cells that are able to contract. They are only cells in the organisms able to do that. Due to contraction, cells change their shape and length. This enables some organ activity (such as heart, or many other organs that are surrounded by smooth muscles that helps them perform their function) or body movements.
Q2. Striated muscles are called striated because of the series of sarcomeres, basic units of striated muscles. They are made up of long cylindrical fiber and attach to the bones. Contraction of these muscles is voluntary <span>except for the heart muscles</span><span>. During these contractions, the muscle is extended by the action of an antagonist muscle.</span>
