DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
Muscle cells can contract and relax and lave fibers as long as 1.5 feet.
Muscles contract and relax all the time. Without more information it is impossible to help you. What reason do you need to relax it or them in the first place. What kind of muscle are you talking about.
Thin strands of DNA are known as double helices and contain genetic information in the form of genes that determine characteristics of an organism. They are composed of two intertwined strands of nucleotides, which are the building blocks of DNA. These strands can vary in length and complexity depending on the organism.
Chromosomes are tightly packed DNA, consisting of long strands of DNA wrapped around proteins called histones. This compact structure helps to ensure that the DNA is able to fit inside the nucleus of a cell and is organized in a way that allows for efficient regulation and replication.
In a cell, the tangles of long strands of DNA form the
DNA
When DNA is in long strands, it typically forms chromatin structures by wrapping around histone proteins to condense into nucleosomes. This packaging allows for the long DNA strands to be compacted within the nucleus of a cell. Additionally, the chromatin structure can undergo further condensation to form chromosomes during cell division.

A polymer made of long molecular strands would generally be more viscous than one made of short molecular strands. Longer molecular chains lead to more entanglement and interactions between chains, resulting in higher viscosity.
