How are the three chromosomal aberrations different from each other?

Answers

Answer 1
Answer: 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.
Answer 2
Answer:

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.

The fibrous outer layer of the eye which retains the overall shape of the eye is the _____. sclera cornea aqueous humor iris

Answers

The best answer is Sclera.The sclera is the tough outer coat of the eye that covers the eyeball except for the cornea. It is a tough opaque tissue that serves as the protective outermost coat of the eye and provides structure and strength to the eye.It is also known as the white of the eye.Attached to the sclera, are six small muscles that control the movement of the eye.In elderly people, the sclera may appear yellow in color.

What is a benefit of genetic engineering?A. Does not require any technology
B. Supported by long term research
C. No controversy surrounding its use
D. Can produce non naturally occuring traits

Answers

Answer: Supported by long term research

One of the many benefits of genetic engineering is that it is being supported by long term research which means this area of knowledge has been thoroughly examined and experimented. There are also inevitable minor issues regarding genetic engineering however, it is not big enough to create doubts on what it can do.
