Answer:
D. A base substitution in gametes during meiosis
Explanation:
Answer:
The fragment and plasmid are both cut with the same restriction enzyme.
Explanation:
To insert a piece of DNA in a bacterial plasmid, we need to cut both plasmid and DNA insert from same regions. This is typically done by restriction enzymes or restriction endonuclease. This cutting will open the plasmid (which is circular initially) and produce <u>sticky ends.</u> Here, DNA insert can attach because of similar sequence (see attached figure). In the final step, DNA ligase will glue it in the plasmid and it will become its part. This technique has been extensively used as a DNA recombinant technology. A better representation can be seen in the attached figure where both DNA sequence of interest and plasmid are cut with the same restriction enzyme (shown as scissors) and then ligated with DNA ligase.

The lack of centrioles in nerve cells prevents them from undergoing mitosis and meiosis, which prevents them from dividing. Nerve cells do not divide throughout their lives and do not lengthen without doing so.

What is nerve cells?</h3>
The central nervous system is constantly receiving information about the external and internal environment (in the form of sequences of action potentials) from nerve cells, also known as neurons.
Nerve cells are “excitable” cells that may convert a range of stimuli into electrical impulses (CNS). Despite the complexity of the nervous system, neurons and glial cells are the only two types of nerve cells that make up nervous tissue.
The structural and operational components of the nervous system are called neurons. Nerve impulses are electrical signals that are transmitted by them. Neuronal support is provided by glial cells.
Therefore, nerve cells do not reproduce and, if damaged by injury or disease, are lost forever.
