Where Is Hereditary Information Stored?

Hereditary information is contained in genes, located in the chromosomes of each cell. Each gene carries a single unit of information.

What molecule stores hereditary information?

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.

Is hereditary information stored in ribosomes?

In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.
