What is the small spherical body within the nucleus?
The small spherical body within the nucleus is called the nucleolus. It is involved in the production of ribosomes, which are essential for protein synthesis in the cell.
What are microtubules made of?
Microtubules are made of protein subunits called tubulin. These tubulin subunits polymerize to form long, hollow tubular structures that are essential for various cellular processes such as cell division, cell shape maintenance, and intracellular transport.
What makes up proteins what are the subunits called?
Proteins are composed of amino acids. These amino acids are joined together by peptide bonds where the -COOH group and the -NH2 group of two consecutive amino acids bond with the loss of a water molecule. The sequence of the amino acids make up the primary structure of the protein.
What is the bond type linking the subunits of proteins together called?
The bond type linking subunits of proteins together is called a peptide bond. It forms between the amino group of one amino acid and the carboxyl group of another amino acid, creating a covalent bond that is essential for protein structure and function.
What is a protein made up of three separate polypeptides called?
A protein made up of three separate polypeptides is called a trimer. Trimeric proteins consist of three individual protein subunits that come together to form a functional complex. Each of the three polypeptides in a trimeric protein may contribute unique structural and functional properties to the overall structure.
Are microtubules tubelike proteins?
Microtubules are not proteins themselves, but rather structures made up of protein subunits called tubulins. These tubulins assemble together to form long, hollow tubes that play a critical role in many cellular processes, including cell division and intracellular transport.
What is the small spherical body within the nucleus?
The small spherical body within the nucleus is called the nucleolus. It is involved in the production of ribosomes, which are essential for protein synthesis in the cell.
What do you call the protein shell of a virus?
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. The capsid encloses the genetic material of the virus.
What is ferritin?
Ferritin is a globular protein complex consisting of 24 protein subunits and is the primary intracellular iron-storage protein in both prokaryotes and eukaryotes, keeping iron in a soluble and non-toxic form. Ferritin that is not combined with iron is called apoferritin.Ferritin is a globular protein complex consisting of 24 protein subunits and is the primary intracellular iron-storage protein in both prokaryotes and eukaryotes, keeping iron in a soluble and non-toxic form. Ferritin that is not combined with iron is called apoferritin.
Viruses are made up of a piece of nucleic acid covered by?
Their RNA or DNA (depending on the virus) is surrounded by a capsid: a protein coat made up of subunits of protein called capsomers
What are the darkly staining area of the nucleus that produces the subunits of ribosomes is?
The darkly staining area of the nucleus that produces the subunits of ribosomes is called the nucleolus. It is responsible for synthesizing ribosomal RNA (rRNA) and assembling ribosomal subunits. The nucleolus plays a crucial role in protein synthesis within the cell.
What is the the structural level when two protein chains combine to form an active protein the structural level is?
The structural level when two protein chains combine to form an active protein is called the quaternary structure. This level of protein organization involves the assembly of multiple polypeptide chains, known as subunits, which can be identical or different. The interactions between these subunits are crucial for the protein's functionality and stability. Examples include hemoglobin and immunoglobulins, which rely on their quaternary structure for biological activity.
What is the protein coat that surrounds a virus called?
The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
What are subunits of protein?
Amino Acids =]Proteins are the building blocks of the human body, and are made up of smaller molecules called amino acids.
What are the subunits of DNA called?
Purines, Pryimidine and Nucleotide are the subunits of DNA.
What is the protein coat the surrounds a virus call?
The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
What is another name for protein coat?
Another name for a protein coat is a "capsid." The capsid is the protein shell that encases and protects the genetic material of viruses, playing a crucial role in their structure and function. It is composed of protein subunits called capsomers, which assemble to form the protective layer around the viral genome.
