Why would you send a copy of the instructions in DNA versus sending the actual DNA molecule?

Biology

DNA is copied because it cannot fit through the nuclear membrane and travel down to the ribosome.
So it is transcribed (translated) to messenger RNA (mRNA). The mRNA can fit through the nuclear membrane and travel down to the ribosome where proteins can be made.

This is why we cannot send the entire DNA molecule itself, it is simply too big to fit. This is why mRNA is extremely important for amino acid production.

Kruka [31]

Researchers selected candidate genes by identifying homozygous tracts shared by all three siblings along with the parental phenotype, this type of study is applied for the inheritance of recessive genes. Since the recessive genes can not be expressed in heterozygous genotype, the back tracking of carriers and homozygous recessive individual will help understand its inheritance pattern. The inheritance of dyt2 can be autosomal recessive. It is usually passed on to progeny of two carriers.

Viruses are made up of cells​
Natali5045456 [20]
What is a virus ?

Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
