Semiconservative Model of DNA Replication
The three different DNA replication models suggested by scientists include: Conservative model of DNA: According to this model the parental DNA will be conserved in the next generation. For example, a cell containing a double stranded parental DNA (represented by black color) will divide by mitosis into two daughter cells. Now, one daughter cell will

What is the Basic Structure of DNA (Deoxy Ribo Nucleic Acid)?
Introduction Structure of DNA The structure of DNA was first revealed through the extraction of nuclein by Meischer. Later, it was identified as nucleic acid, a polymer of nucleotides. These nucleotides are composed of phosphate, sugar, and nitrogenous bases. Watson and Crick’s model of DNA in 1953 demonstrated its double-helix form, a critical structure for
