Some cells like erythrocytes (red blood cells) and thrombocytes (platelets) don't have DNA because they are made from precurors. Erythrocytes are made a process called erythropoiesis and thrombocytes are made by megakaryocytes.

How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
Has how many chromosomes withn the egg cells?
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
Which human cells never have 23 pairs of chromosomes?
Human sex cells which only have a haploid number of chromosomes. 23 total chromosomes. Red blood cells have no chromosomes also.
How many chromosomes are present in human sex cells?
The human sex cell or human gamete has half the number of cells that any other normal human cell would have. A normal human cell (the one from your skin, mouth, lung, liver, sex organs, etc.) has 23 pairs of chromosomes and as such are called diploid cells. The sex cells are haploid having only 23 number of chromosomes as they unite with another haploid cell to create a normal cell with complete set of 23 pairs of chromosomes. The 23rd chromosome on a male human gamete is either the X or the Y chromosome while on the female gamete it is always the X chromosome.
What types of cells contains 23 chromosomes?
Human sex cells.
How many chromosomes are in human kidney cells?
Human kidney cells are body cells, so they would have 46 chromosomes.
How many pairs of chromosomes do each human skin cell have?
Each human cell has 23 pairs of chromosomes or 46 chromosomes.
How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
How are sex cells different from others human cells?
Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes. So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.
How many chromosomes are in the resulting cells after human meiosis?
23 chromosomes
Has how many chromosomes withn the egg cells?
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
Number of chromosomes in eggs and sperm cells?
I assume you mean human egg and sperm cells. There is a haploid number of chromosomes in these cells. 23 chromosomes. n.
How many chromosomes are in their sex cells?
Sex cells have half the number of chromosomes as the original cell, and are said to be haploid. In human sex cells there are 23 chromosomes.
Which human cells never have 23 pairs of chromosomes?
Human sex cells which only have a haploid number of chromosomes. 23 total chromosomes. Red blood cells have no chromosomes also.
Human cells have 23 pairs of these?
