What else can I help you with?
What is the DNA material within a cell that wraps around proteins called?
The DNA material within a cell that wraps around proteins is called chromatin. Chromatin is composed of DNA and proteins, mainly histones, which help in compacting and organizing the DNA within the cell nucleus.
What is tissue madeup of?
Tissue in the human body is made up of millions of cell. Each cell is composed on mostly water along with various proteins, fats, and other stored material.
What are the similarities between a prokarytic cell and a eukaryotic cell?
They both: - contain genetic material (DNA/RNA) - are enclosed in a cell membrane - composed of the same basic chemicals (eg. proteins, nucleic acids) - have ribosomes
What is the living material of a living cell?
The living material of a living cell is primarily composed of proteins, lipids, carbohydrates, and nucleic acids (DNA and RNA). These biomolecules form the structures and carry out the functions necessary for the cell to survive and perform its specific roles in the organism.
What is a cell made up of living material?
A cell is composed of living material called cytoplasm, which consists of water, proteins, lipids, nucleic acids, and various other organic molecules. These components work together to maintain the cell's structure and function.
What surrounds nucleoli and chromatin?
Nucleoli are regions within the nucleus of a cell that are composed of proteins and RNA. They are surrounded by chromatin, which is the complex of DNA and proteins that make up chromosomes. Chromatin forms the structural basis for the nucleus and contains the genetic material of the cell.
What structure composed mainly of proteins and lipids aids in maintain homeostasis in a cell?
cell membrane
What is a cell wall make of?
It is composed of cellulose fiber, polysaccharides, and proteins.
What thin material forms the boundary of the cell?
The thin material that forms the boundary of the cell is called the cell membrane, or plasma membrane. It is primarily composed of a phospholipid bilayer with embedded proteins, which regulate the movement of substances in and out of the cell. This structure not only provides protection but also facilitates communication and signaling between cells.
Where are the ribosomes composed of?
Ribosomes are composed of ribosomal RNA (rRNA) and proteins. The rRNA molecules are synthesized in the nucleolus of the cell and then combine with proteins to form the ribosomes in the cytoplasm.
What material is cell wall chiefly composed of?
HEMICELLULOSE
What is composed of DNA and proteins?
Chromatin is composed of DNA and histone proteins. Histone proteins help package and condense DNA into a complex structure that fits within the nucleus of a cell.
