Lady_Fox [76]

Answer:

The correct answer would be C. The protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence.

Deletion mutation that does not occur in the multiple of three bases can results in frame-shift mutation.

It changes the reading frame of nucleotide in DNA. Thus, the reading frame of codons in mRNA would also change.

Consequently, the sequence of amino acids in a polypeptide chain would change or alter. Thus, a protein would contain many erroneous amino acids.

An example of the same is shown below in the image.

almond37 [142]

Answer:

The correct answer is option C, that is, increase the concentration of the enzyme.

Explanation:

Biological molecules or proteins that enhance the rate of a chemical reaction taking place within the cell are known as enzymes. These proteins play an essential part in the proper functioning of the body, as they help in the process of metabolism and digestion.  

In the given case, if the enzyme gets saturated with the substrate, and is working at optimum pH and temperature, then to enhance the rate of the reaction the only thing that can be done is to enhance the concentration of the enzyme. However, further stimulation of some of the enzymes can be done with the addition of allosteric activators in the reaction, otherwise, enhancing the concentration of the enzyme is the only way.

gavmur [86]

According to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.

<h3>What are uni-axial synovial joints?</h3>

They are synovial joints because they have cartilage and a joint capsule that allow flexion and extension movement, and it is because they move in a single plane or axis that they are considered monoaxial.

In this sense, they can be located in the humeroulnar joint located in the elbow, in the femorotibial or knee joint, allowing the rear sides of the leg to be moved away or closer, and finally in the joints that form between the phalanges of the fingers.

Therefore, we can conclude that according to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.
