The answer is 2 I did the test and got it right
If one wishes to clone a gene using typical restriction endonucleases, how does the restriction endonuclease identify the appropriate cut sites in the genome using the palindromic sequence.
Restriction endonucleases are a family of enzymes usually found in bacteria that cuts DNA at a specific sequence called recognition site. There are three type of restriction endonuclease Type I, Type II, and Type III.
Each endonuclease recognizes a particular sequence called palindromic sequence which is a sequence that reads the same sequence in both the strands either reading from the 3 prime end or 5 prime end.
The endonuclease cuts the palindromic sequence in such a way that it produces sticky ends.

<u>Answer:</u>
<em>The patella articulates with the tibia to form the knee joint.
</em>
<u>Explanation:</u>
<em>Patella is called the knee cap and it gives protection to the knee.</em> Femur is the longest bone in the body and has the function of supporting the weight of the body and enhancing the movement of the legs. <em>The knee joint permits the extension of the lower leg relative to the thigh.
</em>
It allows a 120 degree movement unlike other joints that allow lesser freedom of movement. <em>Patella is the part of the femur that articulates with the tibia and forms the knee joint.

Answer: Hormone
Explanation:
A hormone is a chemical substance produced in small quantities by an endocrine gland (such as thyroid gland in the neck) and carried in the blood to another tissue in the body where it acts as a messenger to control itsfunction.
Examples of hormones include:
- Thyroxine produced by the thyroid gland in the neck
- Testosterone produced by the testis in male humans
- Oestrogen produced by the ovary in female humans
