Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are done without will or conscious control while skeletal muscle is voluntary (in control). While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles, called intercalated discs.
The main difference between cardiac skeletal and smooth muscle is that cardiac muscles perform involuntary muscular movements of the heart, aiding the heart to pump blood throughout the body, while skeletal muscles perform a voluntary muscular movements of bones, aiding physical movements of the body such as walking, running, and writing.
Transcription is important to genetic information. If there is an error during the transcription process, the DNA copies would not be accurate, causing the proteins to be improperly assembled, or not assembled at all.
