Transcription does not take place in erythrocytes (red blood cells) of peripheral human blood. Mature erythrocytes lack a nucleus and other organelles necessary for transcription, as they primarily function to transport oxygen and carbon dioxide. Instead, they rely on the proteins synthesized during their development in the bone marrow before entering circulation.

What are similarities between the human blood smear and the frog blood smear under microscope?
Numerous differences can be seen between frog blood and human blood. Perhaps the most obvious is the oval shape of the frog erythrocytes rather than the biconcave discs of human blood. Moreover, the frog erythrocytes have a nucleus (here stained blue) whilst human erythrocytes do not. There is less difference in size between the erythrocytes and leucocytes than in human blood. There are no platelets in frog blood.
Are there cells in the human body that lack nuclei if so which?
Red blood cells (erythrocytes) do not have nuclei.
What are virtual erythrocytes?
The SSC (self surviving cell) model is only a hypothetical cell; no such cells exist in nature. Thus, it was decided to model living cells so that the simulation results could be evaluated. Human erythrocytes were chosen for the model because intracellular metabolism is limited in human erythrocytes and because they do not replicate, transcribe or translate genes; also, there are already several studies on the modeling of erythrocyte. The construction of a prototype of human erythrocytes using the E-CELL System has been completed,this is referred to as VIRTUAL ERYTHROCYTES.
What kinds of cells has no nucleus?
Prokaryotic cells have no nucleus. In the human body, mature erythrocytes (red blood cells) have no nucleus.
Which type of cell in the human body lacks a cell nucleus?
Red blood cells, also known as erythrocytes, lack a cell nucleus in the human body.
What are some examples of peripheral tissues in the human body?
Some examples of peripheral tissues in the human body include skin, muscles, nerves, and blood vessels. These tissues are located outside of the central organs such as the brain and heart.
What is the peripheral in the human body?
A peripheral in the human body refers to any structure or system that is located outside of the central nervous system, such as nerves, sensory organs, and blood vessels. These peripheral components work together to collect and transmit information to and from the brain.
Is the cell wall visible in human blood cells?
No, because human cells don't have cell walls, only cell membranes.
What are the three types of blood cells in the human body?
Red blood cells (erythrocytes). These cells carry oxygen from the lungs to the rest of the body. White blood cells (leukocytes). These cells help fight infections and aid in the immune process. Platelets (thrombocytes). These help in blood clotting.
What are the 3 main cell types in human blood?
The blood tissue is conformed of three types of cells: The Red Blood Cells or Erythrocytes, that carry oxygen and collect carbon dioxide; White Blood Cells or Leukocytes, that are part of the immune system and Platelets or Thrombocytes, that are involved in homeostasis processes.
What are some types of human cells?
blood cells, white blood cells, sperm cells, brain cells.
Are the largest erythrocytes found in man and monkey?
The largest erythrocytes known to science are found in tailed amphibians, some as large as 56-65 microns. Compare this to ape (including human) red blood cells, which are around 6-8 microns in diameter.
