Double-nucleated protein strands after DNA duplication in interphase what is this?

In this case, we are talking about chromatids – the constituent halves of chromosomes. They include nucleic acids – deoxyribonucleic acid (genetic material – DNA) and special proteins – histones, the purpose of which is to stabilize the chromatid structure. Pay attention to the fact that in the interphase there is a doubling of nucleotides according to the principle of complementarity – that is, only a certain species can be attached near one nucleotide (thymidine corresponds to adenine, and uracil corresponds to cytidine).
