Chromatin is formed when the long DNA molecule wraps around a set of proteins called HISTONE. Histones bind to the DNA molecule, which could are the core of the proteins to form a NUCLEOSOME structure.
Is composed of DNA and protein?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Each nucleosome is composed of DNA wrapped around eight proteins called histones.
Which structure manufactures the components of ribosomes?
Some chromosomes have sections of DNA that encode ribosomal RNA, a type of structural RNA that combines with proteins to make the ribosome. In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome.
What cell structure sorts packages proteins?
The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER.
Is DNA replication part of protein synthesis?
Protein synthesis makes proteins, while DNA replication makes DNA . DNA replication occurs in the nucleus and produces two identical sets of DNA. Protein syntheses produces mRNA, which is then translated by tRNA molecules carrying amino acids to produce a polypeptide or protein.
What is DNA replication and protein synthesis?
The main difference between protein synthesis and DNA replication is that the protein synthesis is the production of a functional protein molecule based on the information in the genes whereas DNA replication is the production of an exact replica of an existing DNA molecule.
What is used in DNA replication and in protein synthesis?
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
Why DNA replication is important before protein synthesis?
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes.
What is the end result of translation in protein synthesis?
The amino acid sequence is the final result of translation, and is known as a polypeptide. Polypeptides can then undergo folding to become functional proteins.
