In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.
It is the semifluid substance that fills up the entire space of the cell and is enclosed by the cell membrane.
Lysosomes are called suicidal bags as they hold digestive enzymes in an enclosed membrane.
Lysosomes are called suicidal bags as they hold digestive enzymes in an enclosed membrane.
cell wall is the outer, protective layer
The endoplasmic reticulum is an organelle that helps ribosomes build proteins.
Golgi apparatus assists in the processing and packaging of proteins and lipid molecules, particularly those destined for cell export.
They are the smallest membrane-bound organelles which comprise RNA and protein. They are the sites for protein synthesis, hence, also referred to as the protein factories of the cell.
The nucleus is a membrane-bound structure that is present only in eukaryotic cells.
Mitochondria's primary function is to produce energy through the process of oxidative phosphorylation. Besides this, it is responsible for regulating the metabolic activity of the cell. It also promotes cell multiplication and cell growth.
