What else can I help you with?
What structures in cells contain DNA and protein?
Nucleus.
What basic protein forms the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes?
Histones are the basic proteins that form the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes. These proteins help to package and condense the DNA within the cell nucleus.
What is the spiral shape of a coiled protein called?
The spiral shape of a coiled protein is called an alpha helix. This secondary structure is formed by hydrogen bonds between amino acids in the protein chain, resulting in a tightly wound helical structure.
What is the name of the rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals called?
The rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals is called a chromosome.
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.
What is the loosely coiled threadlike material in the nucleus?
euglena
What is loosely coiled DNA?
Loosely coiled DNA refers to chromatin, which is the complex of DNA and proteins that makes up a chromosome in the cell. When the DNA is loosely coiled, it allows for easier access to the genetic information for processes such as gene expression and replication. This relaxed state is important for regulating gene activity and enabling various cellular functions.
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.
Coiled threads containing the genetic code are found in?
Chromatin
Where are the chromosomes in the nucleus?
They are inside nucleus.They are coiled only when dividing.
What structures in cells contain DNA and protein?
Nucleus.
What is chromatin in your body?
chromatin is coiled threads containing the genetic code

Which part of the nucleus carries the information for hair colour?
The parts of the nucleus that carries genetic information are the Chromosomes. A chromosome is an organized structure of DNA and protein found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.
What is the name of the rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals called?
The rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals is called a chromosome.
