This video discusses about genome and its replication in prokaryotes and uterus.
00:07
Prokaryotes are the organisms in which the cell flat the presence of membrane -bound oil.
00:26
In these cells, the genetic material present in the form of circular dna within the nucleoid of the cell.
00:46
Nucleoid is a poorly demarcated engine present in the cytoplasm.
00:55
In comparison to eukaryotes, the genome size of proteratres is relatively smaller.
01:09
Eukaryotes are the organisms in which the cells contain membrane -bound organelles, such as chloroplasts and mitochondria.
01:27
Genetic material of nucleots is present in the form of linear tna in the nucleus of the cell, which is a membrane bound organally.
01:47
In comparison to the cokerat's, the genome size of plocariots is larger.
02:01
The cell division with prokaryotes as well as u -karyotes will be discussed.
02:10
In prokaryotes, the cell divides by a mechanism known as binary fusion.
02:23
The process of binary fusion involves four steps.
02:29
The first step is replication of dna.
02:38
The second step is increase in the size of the cell.
02:44
The third step is aggregation of the replicated dna and the fourth and the last step is splitting of the cell.
03:08
Thus, a one cell undergoes these four steps to form two cells whereas in eukaryotes two types of cell division process are observed observed, one is mitosis in which two genetically identical daughter cells are formed.
03:44
This means that the daughter cells contains the same number of chromosomes as the parent cell.
03:50
Whereas in meiosis, four daughter cells are formed that contain half the number of chromosome in comparison to the parent cell...
