WebApr 8, 2024 · A chromosome can be defined as an entire chain of DNA and it comes along with a group of stabilizing proteins. Chromosomes seem to be thread-like in appearance and are located inside the nucleus of an animal and plant cells. As discussed above, each chromosome is made up of protein and DNA (a single molecule). WebTypes of DNA: DNA duplex model proposed by Watson and Crick is right handed spiral and is called B-DNA (Balanced DNA). In the model the base pairs lie at nearly right angles to the axis of helix (Fig. 6.5 D). Another right handed duplex model is A-DNA (Alternate DNA). Here, a single turn of helix has 11 base pairs. fish roe protein
