What are the highly condensed portion of chromatin which appear as very dark areas in a transmission electron micrograph?
which is the loosely condensed chromatin where genes are expressed
Structure of nucleosome and extent of chromatin condensation in metaphase chromosome?
A nucleosome is the basic unit of chromatin, composed of DNA wrapped around a core of histone proteins. In metaphase chromosomes, chromatin is highly condensed and tightly packed. The nucleosomes are further condensed into tightly coiled structures called chromatin fibers, ultimately forming the highly structured chromosomes observed during cell division.
What is the condensed form of DNA referred as?
The highly condensed forms of DNA (and proteins) are known as chromosomes.
What are uncoiled chromosomes in the nucleus of non dividing cells called?
Chromatid
How does DNA make itself more compact?
DNA can compact itself through a process called DNA condensation, where it wraps around proteins called histones to form structures called nucleosomes. These nucleosomes then coil and fold into higher-order structures, ultimately leading to the highly compacted form known as chromatin. This compaction allows the long strands of DNA to fit within the nucleus of a cell.
Why does chromatin remodeling have to be the first step in gene activation?
Eukaryotic DNA can be highly packaged in condensed chromatin and inaccessible to transcription factors and RNA polymerase.

Medical Transcription in Orlando?
Yes, a medical transcription school in Orlando, Florida that offers online classes would be the Medical Billing School. It is highly rated.
What are the dark staining rod shaped structures that are composed of highly coiled chromatin and found in cells undergoing cell division called?
The dark staining rod-shaped structures found in cells undergoing cell division are called chromosomes. They are composed of highly coiled chromatin, which is a complex of DNA and proteins that condenses to form chromosomes during cell division. Each chromosome contains the genetic information that is passed on to daughter cells.
In interphase the DNA in the form of loose threads called?
In interphase, DNA exists in the form of chromatin which consists of loosely packed threads of DNA along with proteins. This allows for easy access to the genetic material for processes like gene expression and DNA replication.
How do members of a highly mobile and diverse society compensate for the lack of accessible kin?
Members of a highly mobile and diverse society compensate for the lack of accessible kin by diversifying and associating with people outside of their immediate family.
Highly impermeable layers such as compacted clay or shale are known as?
Highly impermeable layers such as clay or shale are referred to as an aquitard. While permeable sand and limestone that can transmitt large amounts of water to a well are referred to as an aquifer.

What two rod structures contain the cell's DNA?
The two rod structures that contain the cell's DNA are chromosomes and chromatin. Chromosomes are highly condensed structures that contain the DNA during cell division, while chromatin is the relaxed form of DNA that is present in the nucleus during interphase.
