No , both strands are replicated in opposite directions , which gives rise to the name " leading " and " lagging " strands as one strand is replicated faster than the other . DNA is replicated only from 5' to 3' so only one strand can be replicated in the 5' to 3' continously ( leading ) while the other is in the opoosite direction . u probably wont understand this mechanism easily through words so i suggest u watch a video on youtube if u still dont get it !
<u><em>Mitosis</em></u> is the division in which two identical daughter cells are generated from a mother cell
Answer:
39 double-helical DNA molecules will be presenet in sperm and 39 in egg.
Explanation:
Each chromosome is made up of histone protein and a molecule of DNA.
Each cell contain double number of chromosomes (2n) except a few exceptions like sperm (1n) and egg (1n).
Human body cells contain 46 chromosomes while sex cells contain 23 chromosomes because of meiosis. Similarly dog cells contain 78 chromosomes while their gametes i.e egg and sperm each contain 39 chromosomes. The fertilization of sperm and egg will restore the chromosome numbers.
<em>As there is only one double helix DNA present in chromosome, so there would by 39 double helix DNA in sperm and 39 double helix DNA in egg. </em>
