Question

DNA is typically found in cells in the form of a very long strand that is coiled many
times and contains thousands or millions of nitrogen bases. Which term
describes this very long molecule of DNA?

Answer 1

Answer:

This very long molecule of DNA is called chromosome.

Explanation:

• Chromosome is a 'DNA molecule' that contains part or all of the genetic material of an organism.

• The 'three-dimensional genome structure' of chromosome plays a vital role in 'transcriptional regulation'.

• Prokaryotes have less sequence-based chromosome structure than eukaryotes.

• The recombination of chromosome during meiosis and successive reproduction plays a significant role in 'genetic diversity'.

• Chromosomes are normally visible under microscope during the metaphase of cell division. Chromosomes are the key elements of cell division.
