Genetic material
Two different kinds of genetic material exist: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Genetic Material
Viruses may carry DNA or RNA as their genetic material. DNA may be single- or double-stranded (ssDNA and dsDNA), and it may be circular or linear.

The genetic material of an organism consists of deoxyribonucleic acid (DNA).

The genetic material in retroviruses is in the form of RNA molecules, while the genetic material of their hosts is in the form of DNA. When a retrovirus infects a host cell, it will introduce its RNA together with some enzymes into the cell.

Since all cells come from existing cells, they must have some way of reproducing, whether that involves asexual (no recombination of genetic material) or sexual (recombination of genetic material).

And as a geneticist talking about deletion it means something is missing of the genetic material.

The common ancestor of all life probably used RNA as its genetic material. This ancestor gave rise to three major lineages of life.

The complexity of the relationship between kinetochores and the mitotic spindle reflects the requirement for accurate distribution of the genetic material between dividing cells.

Crossing over is important for genetic variety as it allows the exchange of genetic material between the maternal and paternal chromosomes. This forms chromatids with new combinations of alleles (recombination of linked genes).

Vegetative reproduction: (Also called vegetative propagation.) A reproductive process that is asexual and so does not involve a recombination of genetic material.

A virus is little more than a strand of genetic material (DNA or RNA) surrounded by a protein known as capsid. Viruses do not carry out any metabolic processes and need to invade a living host (animal, plant, bacterium or fungus).

All organisms pass on their heredity via the genetic material which is based upon the nucleic acid DNA using a universal genetic code.
