What are nucleosomes?
Q: What are nucleosomes?
A: Nucleosomes are the building blocks that make up chromosomes. They consist of a segment of DNA wound around a histone protein core.
Q: What is chromatin?
A: Chromatin is a substance that consists of DNA and a protein.
Q: What happens to chromatin to form nucleosomes?
A: Chromatin is packed up to form nucleosomes.
Q: What are the three things that packages of nucleosomes do?
A: The packages of nucleosomes do three things: they function in cell division, they wrap up the very long DNA in a shorter package, and they regulate the gene action in cells.
Q: What is the function of chromosomes in cell division?
A: The function of chromosomes in cell division is to ensure the equal distribution of genetic material between daughter cells.
Q: What is the role of histone proteins in nucleosomes?
A: Histone proteins act as a core around which a segment of DNA is wound to form a nucleosome.
Q: What is the role of proteins in regulating gene action in cells?
A: Proteins play a role in regulating gene action in cells by helping to control the expression of genes.
