Question

Which biomolecular group carries and passes on the hereditary information
of the organism?​

Answer 1

We now know that the DNA carries the hereditary information of the cell (Figure 4-2). In contrast, the protein components of chromosomes function largely to package and control the enormously long DNA molecules so that they fit inside cells and can easily be accessed by them.

Answer 2

DNA is responsible for passing the hereditary information of an organism. These nucleic acids occur as deoxyribonucleic acid (DNA) or ribonucleic acid (RNA).

Explanation:

• Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many virus.
• The function of DNA is to store all of the genetic information that an organism needs to develop, function and reproduce.
• Each cell contains a full complement of genes, yet cells from different tissues and organs look and behave differently.
• The reason is that only some of the DNA of each cell is used to make proteins.
• The four roles DNA plays are replication, encoding information, mutation/recombination and gene expression.
