Explanation:
Translation occurs at the ribosome, which consists of rRNA and proteins. ... Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein. Learn how their functions are based on their three-dimensional structures, which ... bonds are formed by a biochemical reaction that extracts a water molecule as it joins to protein structure because these side chains can bond with one another to these stable folding patterns make up the secondary structure of a protein. A genotype is an organism’s set of heritable genes that can be passed down from parents to offspring. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc. An example of a characteristic determined by a genotype is the petal color in a pea plant. Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
Answer: The primary motor cortex for control of voluntary muscles is found in the precentral gyrus of the frontal lobes.
Explanations:
The primary motor cortex is one of the important brain areas involved in motor function. It is found in the precentral gyrus of frontal lobes. It control voluntary muscles and generate impulses needed for movement execution.
Voluntary muscles are muscles that we can control consciously or we can control them at will and we can choose when we want to use them. They are also refers to as skeletal muscles and are attached to bones. The are majorly use for locomotion.
