Chromosomes are mostly DNA not proteins, but there are small proteins that "package" and protect the DNA. These proteins are somewhat different in prokaryotes and eukaryotes:
- Prokaryotes do not possess nuclei. Instead, their DNA is organized into a structure called the nucleoid. This structure is, however, dynamic and is maintained and remodeled by the actions of a range of histone-like proteins, which associate with the bacterial chromosome. In archaea, the DNA in chromosomes is even more organized, with the DNA packaged within structures similar to eukaryotic nucleosomes.
- In the nuclear chromosomes of eukaryotes, the uncondensed DNA exists in a semi-ordered structure, where it is wrapped around histones (structural proteins), forming a composite material called chromatin.
What else can I help you with?
What chromosome is the HBB gene on?
The HBB gene, which codes for the beta globin protein, is located on chromosome 11.
What does the rp13 gene code for on chromosome 17?
The rp13 gene on chromosome 17 codes for a protein that is part of the ribosome, which is essential for protein synthesis in cells. Mutations in this gene can lead to disorders affecting protein production and cellular function.
What spooled string of genes inside the nucleus?
A spooled string of genes packaged in a single unit is called a chromosome. A chromosome is a structure of DNA, RNA, and protein which are found in cells.
What two structures make up a single replicated chromosome?
DNA and Protein
What is the protein handle on a chromosome?
The protein handle refers to specific regions on a chromosome where proteins can bind and interact with DNA. These protein handles help regulate various cellular processes such as gene expression, DNA replication, and chromosome structure. They play a crucial role in organizing and controlling the functions of the chromosome.
What is the definition of chromosome mutation?
A chromosome is an organized structure of DNA and protein that is found in cells.In biology, mutations are changes to the nucleotide sequence of the genetic material of an organism.
Is a chromosome a protein?
no it is not
What chromosome is the HBB gene on?
The HBB gene, which codes for the beta globin protein, is located on chromosome 11.
What makes up a chromosome?
A chromosome is made up of DNA, protein, and RNA. The DNA contains the genetic information necessary for an organism's growth and development, while the proteins help the DNA stay organized and compacted within the chromosome structure. RNA is involved in various functions related to gene expression and regulation.
A segment of DNA found on a chromosome that codes for a protein?
a gene
What does the rp13 gene code for on chromosome 17?
The rp13 gene on chromosome 17 codes for a protein that is part of the ribosome, which is essential for protein synthesis in cells. Mutations in this gene can lead to disorders affecting protein production and cellular function.
What chromosome does cystic fibrosis effect?
The gene on chromosome 7 produces a protein called cystic fibrosis trans-membrane regulator. Mutation in the DNA level of chromosome 7 leads to the absence of this protein which leads to cystic fibrosis. Cystic fibrosis is a recessive disease.
What spooled string of genes inside the nucleus?
A spooled string of genes packaged in a single unit is called a chromosome. A chromosome is a structure of DNA, RNA, and protein which are found in cells.
Is chromosome a type of gene?
A chromosome is a collection of many genes and protein substrates upon which the genes are strung, rather like beads on a string.
Parts of chromosome that specify amino acid sequence in protein?
pattern of sugar
