Answers

Answer:

C. Genetic engineering.

Explanation:

Genetic engineering refers to the deliberate alteration or manipulation of an organism's genes or genetic material for practical purposes. This can involve various techniques such as inserting, deleting, or modifying specific genes to achieve desired traits or outcomes. Genetic engineering is widely used in biotechnology and has numerous practical applications in agriculture, medicine, and other fields.

Imagine that you are observing an enzyme-catalyzed reaction in the lab. Every time you add more enzyme, the reaction rate increases proportionally until the reaction rate suddenly levels off. No other chemicals were added, and no modifications were made in the experimental setting. Why do you think the reaction rate stopped increasing?

Answers

The rate of reaction stops increasing because there is no substrate left to bound with an enzyme to increase the rate of reaction.

What is an enzyme?

An enzyme is a substance that increases the rate of reaction by catalyzing the reaction.

The enzyme is called a biological catalyst.

Enzyme work when it combines with the substrate of the reaction to make products.

When the enzyme is added, the rate of reaction increase because it fastens the reactions.

But when the substrate is converted into a product and there is no substrate left to combine with enzyme the rate of reaction stop increasing.

Thus, The rate of reaction stops increasing because there is no substrate left to bound with an enzyme to increase the rate of reaction.

Answer:

All the substrates are bound to the enzyme, thats why the reaction rate stopped increasing.

Explanation:

Actually an enzyme works by binding a substrate molecule to its active site, producing a product  , resulting in an increase in the rate of reaction.

            Enzyme + substrate = Enzyme + product

Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and there are no substrates left.Hence the reaction rate stopped increasing.

How are the three chromosomal aberrations different from each other?

Answers

The three chromosomal aberrations are: (1) Inversion; (2) Translocation and (3) Deletion. They are all different as they have opposing functions of repairing, changing or removing chromosomal differences. Inversion involves breaking the chromosome and inserting another part; translocation involves a part of the chromosome moving to another place, and deletion is where parts are simply deleted and removed.

Chromosomal aberration is referred to as the abnormalities in chromosome and they are of many types. They are different from each other because;

Duplication: It duplicates the specific part of a chromosome and leads to extra genetic material.

Deletion: In this, deletion or disappearance of a specific sequence of a chromosome occurs.

Translocation: In this one portion of a chromosome is transferred to another chromosome.

Further Explanation:

If there is any defect in the chromosome or the sequence of the chromosome, then this condition is referred to as chromosomal aberration. These problems give physical abnormalities or symptoms in an individual. Chromosomal aberration could be developed due to the addition of a particular portion in the chromosome or deletion of a particular sequence from the chromosome. It affects the normal functioning of the chromosome. The two types of chromosomal aberration are:

Numerical aberration: It develops due to the presence of an extra number of the chromosomes or lack of chromosome. For example, Turner syndrome and Down syndrome.

Structural aberration: This is developed due to abnormality in the genetic material or loss of genetic material.

Structural aberrations are of many types. Few of them are:

Deletion: In this, a particular sequence is missing from the chromosome.

Duplication: In this, some part of the chromosome is duplicated.

Translocation: In this, part of the chromosome is moved to another chromosome.

Inversion: In this, the genetic material of a chromosome is inverted due to breakage.
