Can you see chromosomes during interphase?
No. Chromosomes aren't visible until Prophase.
No, during interphase the cell's DNA is still linear (in a double helix structure). It is only during mitosis (during the anaphase) in which the DNA condenses to form chromosomes with 2 chromatids each. When the DNA is replicated during the interphase, it is still linear and is not yet in the form of chromosomes and chromatids.
