In prokaryotes the genes directly specify proteins.

In eukaryotes the exons within the genes specify proteins, the introns within the genes are noncoding DNA that alternate with exons and are spliced out in the process of transcription to messenger RNA.

A chromosome in humans is made up of one long DNA molecule. This DNA molecule is double-stranded and contains thousands of genes.


What is a long DNA molecule that contains genes and has proteins to help it Retain its shape?

A long DNA molecule that contains genes and is associated with proteins to help maintain its structure is called a chromosome. Chromosomes are made up of DNA wrapped around histone proteins, which facilitate efficient packaging and organization within the cell nucleus. This arrangement not only protects the genetic material but also plays a crucial role in gene regulation and expression.

Does each chromosome have a very long DNA molecule with hundreds of thousands of genes?

Yes, each chromosome contains a single, long DNA molecule that can house tens of thousands of genes. Genes are segments of DNA that contain the instructions for making specific proteins, which then determine an organism's traits and functions. In humans, each cell typically contains 23 pairs of chromosomes, for a total of 46 chromosomes.
