What else can I help you with?
What is composed of polysaccharide and polypeptide?
Glycoproteins are composed of polysaccharide chains (carbohydrates) covalently linked to polypeptide chains (proteins). These molecules play important roles in cell signaling, recognition, and structure in living organisms.
Which cell helps the organelle manufactures proteins?
Ribosomes are the organelles responsible for manufacturing proteins within cells. They can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER. Ribosomes translate messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins.
Will point mutation CAUSE a cell to make an incomplete polypeptide if the mutation results in a stop codon?
Yes it will.
What does the rough E R do for a plant cell?
The rough endoplasmic reticulum (RER) in a plant cell is primarily responsible for the synthesis and processing of proteins. Its surface is studded with ribosomes, which translate mRNA into polypeptide chains, leading to the production of proteins that are often destined for secretion or for use in the cell membrane. Additionally, the RER helps in the proper folding and modification of these proteins, ensuring they are functional and properly assembled before they are transported to their final destinations within or outside the cell.
Will a point mutation cause the cell to make an incomplete polypeptide if the mutation results in a stop codon?
Yes, a point mutation will cause the cell to make an incompelete polypeptide chain that is non-functional, if the mutation results in a stop codon. This type of a mutation is also called as the Nonsense Mutation.
Is plant cell has polypeptide?
Yes
What tools that help a cell translate?
The main tools involved in the process of translation in a cell are ribosomes, transfer RNA (tRNA) molecules, messenger RNA (mRNA), and various protein factors. Ribosomes act as the machinery where translation occurs, while tRNA molecules bring amino acids to the ribosome based on the mRNA codon sequence. Protein factors help in initiating, elongating, and terminating protein synthesis.
How could a change in a polypeptide affect cell activity?
Enzymes are derived from polypeptide chains, enzymes are responsible for adequate cell activity. Therefore, if a polypeptide chain is not properly composed, the enzyme will be dysfunctional, hence leading to a depletion in cell activity.
Do monera have cell walls?
Yes, made of polysaccurid with polypeptide
The receptors for catecholamine and polypeptide hormones are found?
on the outer surface of the target cell
Amino acids that are not yet part of a polypeptide are found in which part of the cell?
Amino acids that are not part of a polypeptide are typically found in the cytoplasm of a cell. They are either freshly synthesized by ribosomes or recycled from proteins that have been degraded.
Describe the path of a newly synthesized polypeptide from a ribosome to the cell surface?
After synthesis in the ribosome, the polypeptide chain is usually transported to the endoplasmic reticulum (ER) where it undergoes post-translational modifications and folding. From the ER, the polypeptide enters the Golgi apparatus for further processing before being packaged into vesicles and transported to the cell surface. Finally, the vesicle fuses with the cell membrane, releasing the polypeptide to the cell surface.
A point mutation will cause the cell to make an incomplete polypeptide if the mutation results in?
