Lysosomes are found in almost every animal eukaryote cell. What is their function The function for a lysosome is to break down debris and any other unwanted things within the cell (sometimes referred to as stomach of cell)
The nucleus regulates all cell activity. It does this by controlling the enzymes present. The chromatin is composed of DNA. DNA contains the information for the production of proteins. This information is encoded in the 4 DNA bases. Adenine, thymine, cytocine, and guanine. The specific sequence of these bases tells the cell what order to put the amino acids.
There are three processes that enable the cell to manufacture protein:
Replication allows the nucleus to make exact copies of its DNA
Transcription allows the cell to make RNA working copies of its DNA
In translation the Messenger RNA is used to line up amino acids into a protein molecule
Nucleus the most prominent organelle of the cell. The number of nuclei may vary, they may be uni-nucleate (single nucleus), bi-nucleate (two nuclei) or even multi-nucleate.
Nucleus is present in all eukaryotic cells, they may be absent in few cells like the mammalian RBCs.
The shape of the nucleus is mostly round, it may be oval, disc shaped depending on the type of cell.
