No. The only hereditary material is DNA. But histones are actually pretty interesting in their own right. They can affect what genes are available to be expressed by a cell. Some researchers think that modifications to histone proteins can be transmitted at mitosis from a mother cell to the daughter cells, thus maintaining a certain pattern of gene expression. This is part of a field called epigenetics.

What parts of a cell contains hereditary materials?
the mitochondria
Old idea that hereditary materials from parents mix in offspring?
Blending
Chromatin contains proteins called?
Histones are the main proteins in chromatin, histones are a group of five small basic proteins in the nucleus.
What is the name for strands of DNA wound around proteins?
chromosomes. The DNA is genes that are tightly wrapped around proteins. The proteins are histones.
What protein does DNA wrap around?
Histones are the major proteins involved in coiling DNA.
To help with biology homework what are histones?
Histones are proteins found in eukaryotic cell nuclei. They are high in alkaline. Histones package and order the DNA into units that are called nucleosomes.
What role do histones play in a cell?
DNA strands are wrapped around the histones. In order for DNA to be accessible, histones must be modified (acetylation). If the histones are "protected" at a particular locus from modification, the genes are silenced and cannot be expressed.
What is a non histones protein?
Non-histones protein are classified as the proteins that are left after the histones have been removed in chromatin. DNA polymerase and scaffold proteins are non-histone proteins.
Does histones and DNA molecules relate to each other?
Histones are a part of DNA. Histones are actually 8 molecule of proteins joined together and the DNA strand wraps around the the histone in a circular manner. Histones are present on the DNA strand at regular intervals.
Which organelle surrounds the cell membrane and contains hereditary material?
The Nucleolus of the Nucleus in any eukaryotic cell contains the hereditary material. While, prokaryotic cells hereditary material is located within the cell membrane floating freely in the cytoplasm.
Term for the group of proteins that organizes and condenses long strands of DNA into light coils?
HISTONES
When does DNA begins to condense with help of structural proteins like histones?
as soon as histones are put in solution with DNA it begins to condense. Just by being there the positively charged histones are attracted to the negatively charged DNA. DNA wraps around histones and other structural proteins condensing to metaphase chromosomes.
