Answer:
the organelle that regulates cell function and contains the DNA is a nucleus
Answer:
- All of the following are correct
- Muscle cells are surrounded by a branching network of transverse tubules.
Explanation:
Muscle cells are composed of myofibrils, which are the fundamental and functional parts of a muscle cell. Myofibrils are the ones that are surrounded by a branching network of transverse tubules. These transverse tubules are extensions of the sarcolemma or the muscle cell's membrane. Their distribution and connection to myofibrils allow for the passage of Calcium ions needed for contraction.
Ans.
Errors that occur during DNA replication lead to mutations, which represent permanent, heritable changes in genetic material. These errors can pass from parent cell to daughter cells and affect many generations of cells.
On the other hands, errors that occur during protein synthesis lead to formation of defected or non-functional protein. These errors cannot pass from one cell to another and affect only one cell, which requires that protein for its proper functioning.
Thus, 'it is more important to check errors during DNA replication that errors during protein synthesis.'
Judging by the hair, you can find it's origin and as long as if you had a group of people to be looking at you can match the color and DNA of each person's hair to the hair you found when you were doing your forensics were at said crime scene. I don't necessarily know the processes that were taught but the <em>investigation</em> wouldn't be too difficult.
