A complex of proteins and DNA strands that are loosely coiled such that translation and transcription can occur?
diarrhea
What is the spiral shape of a coiled protein called?
Helix
Why is the DNA in the nucleus loose and not well defined into chromosomes?
In the interphase nucleus the chromatin exists in two forms; loosely coiled form called euchromatin and tightly coiled form called heterochromatin. These two types become much more coiled to form the chromosome at the time of cell division. Now come to the point. When DNA is a bit loosely colied, that is, in the euchromatin, its bases are available for transcription. On the other hand, when it is in the form of heterochromatin, the bases are not accessible for reading by RNA polymerase, hence transcription is not possible. As majority of genes must be transcribed in the nucleus, so the chromosomes must be decondensed to appear in the form of chromatin, and that too in the form of euchromatin. If the DNA remained organized in the form of chromosomes, genes would remain inactive in the sense that they would not be acessible for transcription.
Name the cell organelles which contain DNA?
The three organelles that contain DNA are the nucleus, mitochondria, and chloroplasts. The nucleus contains the largest amount of DNA in the cell.
What is the protein around which chromosomal DNA is coiled?
Histones are the most abundant proteins found in chromosomes.
What is the loosely coiled threadlike material in the nucleus?
euglena
What is loosely coiled DNA?
chromatin
What molecule is a chromosome made of?
protein and DNA Each chromosome in the nucleus includes one macromolecule of DNA, folded and coiled with protein molecules to reduce its size.
A complex of proteins and DNA strands that are loosely coiled such that translation and transcription can occur?
diarrhea
What are coiled protein strands that have barbs tipped with poison?
A nematocyst is a coiled protein strands that have barbs tipped with poison. It is a capsule within a specialized cells.
What is formed with coiled up DNA?
Coiled up DNA, combined with protein histone, forms chromosomes.
Where are the chromosomes in the nucleus?
They are inside nucleus.They are coiled only when dividing.
Coiled threads containing the genetic code are found in?
Chromatin
What is the spiral shape of a coiled protein called?
Helix
What is chromatin in your body?
chromatin is coiled threads containing the genetic code

What is DNA coiled up into thread like structures called?
When DNA is in its coiled up form, it is called a chromosome. These exist in the nucleus of each cell.
