primitive life consisted of RNA,which was a self replicating molecule.RNA molecule was surrounded by a lipoprotein vesicle and formed a primitive cell,which formed proteins.then the DNA molecule was produced from the RNA molecules by reverse transcription.then DNA replaced RNA as the genetic material.Likewise the first cell was formed that was coacervaetes.

Where do haemoblasts originate?
Haemoblasts originate in the bone marrow. They are stem cells that give rise to all blood cells in the body, including red blood cells, white blood cells, and platelets.
Where do Schwannomas originate?
Schwannomas originate in the Schwann cells
Stem cells responsible for the production of white blood cells originate in what?
Stem cells responsible for the production of white blood cells originate in the bone marrow. These stem cells differentiate, or specialize, into various types of white blood cells including lymphocytes, neutrophils, and monocytes.
B cells and t cells both originate from stem cells in the?
B cells and T cells both originate from the haematopoietic (or hematopoietic) stem cells located in the bone marrow. T cells mature in the thymus. B cells mature in the secondary lymphoid tissues (such as the spleen).
What cells originate from monocytes?
Macrophages and dendritic cells originate from monocytes. Monocytes are a type of white blood cell that circulate in the bloodstream and can differentiate into macrophages which are involved in immune responses and tissue repair, or dendritic cells which play a key role in presenting antigens to activate T cells in the immune system.
Where do t cells come from?
All T-cells originate in the same place in humans. They originate from hematopoietic stem cells which are located in the bone marrow.
Where do haemoblasts originate?
Haemoblasts originate in the bone marrow. They are stem cells that give rise to all blood cells in the body, including red blood cells, white blood cells, and platelets.
Where do Schwannomas originate?
Schwannomas originate in the Schwann cells
Where do blood cells originate in the human body?
Blood cells originate in the bone marrow of the human body.
Does T- cell development begin in the spleen?
Wikipedia: All T cells originate from haematopoietic stem cells in the bone marrow.
Where do natural killer (NK) cells originate in the human body?
Natural killer (NK) cells originate in the bone marrow of the human body.
From where do all plant tissues originate?
All plant tissues originate from meristematic cells, which are found in the growing regions of the plant such as the root and stem tips. These meristematic cells continually divide and differentiate into various types of plant tissues, including vascular, epidermal, and ground tissues.
Do all cells have a parent-cell?
All cells originate from a previous cell, and if there is only one of them it is called the "parent cell". In the context of reproducing, the cell made from a parent cell is called the "daughter cell".
Stem cells responsible for the production of white blood cells originate in what?
Stem cells responsible for the production of white blood cells originate in the bone marrow. These stem cells differentiate, or specialize, into various types of white blood cells including lymphocytes, neutrophils, and monocytes.
Where do the microtubules of the spindle originate during mitosis in both plant and animal cells?
In plant cells, the microtubules of the spindle originate from the microtubule-organizing centers (MTOCs) located at opposite poles of the cell. In animal cells, the microtubules of the spindle originate from the centrosomes, which are also located at opposite poles of the cell.
Where do B cells and T cells originate?
They both originate in the red bone marrow. B lymphocytes mature there. T lymphocytes mature in the thymus gland.
What are the different types of blood cells and their study and fuctions?
There are three kinds of blood cells, red, white, and plasm blood cells. Also called eurythrocytes, leukocytes, and thrombocytes. They all originate from a pluripotent stem cell.
