What do DNA molecules and its associated proteins coil to form a?
DNA molecules coil around histone proteins to form a structure called a nucleosome. Multiple nucleosomes are further coiled and compacted to form chromatin, which then condenses into chromosomes during cell division.
How many folds is DNA compacted in your chromosome?
Several; DNA is super-coiled in its chromosomal state. It coils like this with the assitance of packaging proteins such as histones, condensins and cohesins. Different chromosomes (and organisms) have different packaging ratios. For example, the shortest human chromosome has an un-coiled DNA length of about 14,000 micrometers. In its chromosomal state, it has a length of about 2 micrometers, giving it a packaging ratio of 7,000.
When DNA is in long strands prior to colling?
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.
What is DNA organization?
genetics
How is DNA condensed into a nucleus?
Protein involved in DNA condensation. In most eukaryotes, the chromosomal packing involves the wrapping of DNA around a core of histones to form nucleosomes. Adjacent nucleosomes are packaged together via Histone 1 and nucleosomes are organized into a 30 nm chromatin fiber. DNA condensation takes place as cells enter mitosis or when germ cells enter meiosis.
What is Tightly coiled form of DNA called?
Coiled up DNA, combined with protein histone, forms chromosomes.

What is the full name for B DNA?
B DNA stands for B-form DNA, which refers to the most common structural form of DNA found in nature.
Within a cell DNA is compacted along with proteins into structures called?
Chromatin
What holds the DNA in a eukaryotic cell?
In a eukaryotic cell, the DNA is held within the nucleus. The DNA is organized into structures called chromosomes, which are further compacted by proteins to form chromatin. The nucleus is surrounded by a nuclear membrane that helps protect the DNA and regulate its interactions with the rest of the cell.
What form is DNA during interphase?
During interphase the DNA is in loose form. It makes the chromatin inside the nucleus. The chromatin allow access to RNA and DNA polymerases that transcribe and replicate DNA.During interphase the DNA is in loose form. It makes the chromatin inside the nucleus. The chromatin allow access to RNA and DNA polymerases that transcribe and replicate DNA.
What form of DNA is most stable A B or Z?
B-DNA is the most stable form of DNA due to its regular right-handed double helical structure. A-DNA and Z-DNA are less common and tend to form under specific conditions, such as high salt concentrations in the case of A-DNA and alternating purine-pyrimidine sequences in the case of Z-DNA.
Where do fossil rocks are most form?
Under the earth surface when dirt is compacted and it is pushing against something hard...
When DNA becomes compacted it forms the structure?
In the very first step of mitosis, the prophase.

Lithification is most likely closely related to?
the process of sediment becoming compacted and cemented together to form sedimentary rock.
