Detailed explanation-1: -A chromosome contains many genes. A gene is a segment of DNA that provides the code to construct a protein. The DNA molecule is a long, coiled double helix that resembles a spiral staircase.
Detailed explanation-2: -Type I genes tend to be involved in immune response or sensory receptors while type III genes are involved in cell to cell signalling and type II genes are a complex mix of all three types.
Detailed explanation-3: -1) The ori is the place where DNA replication begins, enabling a plasmid to reproduce itself as it must to survive within cells. Ori is the site for the origin of replication. This does not take part in any kind of gene expression and thus is not a part of any gene. Its function is to govern genome duplication.
Detailed explanation-4: -Centriole is not present in chromosomes, it is a cell organelle.
