Each chromosome is a single molecule of _____ whose extraordinarily long length can be compacted by as much as ______-fold during ______ and tenfold more during _____. This is accomplished by binding to _______ that help package the DNA in an orderly manner so it can fit in the small space delimited by the. The structure of the DNA-protein complex, called ______, is highly ______ over time. 10,000 chromosome mitosis 100 different nuclear envelope 1000 DNA nucleolus cell cycle dynamic proteins cell wall interphase similar chromatin lipids static

Explanation / Answer

Please find the correct order:

DNA, 100, Interphase, mitosis, proteins, nuclear envolope, chromatin, dynamic.

Reason: The chromosome is a single extended linear strucutre which is made up of DNA. The structure of DNA or chromosome becomes highly condensed or extended over 100 to 10,000 times over different phases of cell cycle. The chromosomes become condensed by binding to different nuclear proteins and become nucleosomes. This structure is called nucleosomes is formed by binding to histone proteins. The reason for binding of proteins to DNA and condensation of DNA is the limitation of size of nucleus. Thus, the chromatin is a highly dynamic structure.
