What is the carrier of genetic material?
Nucleic acid is the carrier of genetic information, and it is of two principal types: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
What are gene carriers called?
Instead, a carrier called a vector is genetically engineered to carry and deliver the material. Certain viruses are used as vectors because they can deliver the material by infecting the cell.
What is a carrier and who can be a carrier?
A carrier is a person who can pass an inherited (genetic) disease on to their children but who does not have the disease. The person can also pass on carrier status. Some diseases are caused by changes in a person’s chromosomes or genes.

Why DNA is called carrier of information?
The DNA is replicated and passed on to the next generation so that the cells can perform the same activities as that of the parent cell. So, the DNA which code for genes is considered as the carrier of genetic information in most of the living organisms.
Why DNA is the carrier of genetic information?
Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand. The genetic information stored in an organism’s DNA contains the instructions for all the proteins the organism will ever synthesize.

How common is it to be a genetic carrier?
It is estimated that everyone is a carrier of around half a dozen rare recessive genetic mutations Structural changes in a gene – they can be alterations to a gene’s size, arrangement, or molecular sequence. that could lead to disease – this is actually normal and not something to be uncomfortable about.
