In eukaryotes (animals, plants, fungi, algae) chromosomes are found in the nucleus.
There is also DNA in mitochondria and chloroplasts, which is usually referred to by terms like "mitochondrial DNA" or "the chloroplast genome". The word "chromosome" is not generally used for this DNA.
Prokaryotes (bacteria) have a single chromosome in a region of the cell called the nucleoid. Scientists do not use the term "nucleus" for prokaryotes, as there are no membranes inside the cell, and therefore no nuclear membrane. So, no nucleus!
The nucleus.
In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.
Sex cells have 1/2 the number of chromosomes of a normal cell (23)
Branch of science that is concerned with the study of chromosomes and cell-division . It includes study of normal chromosomes and investigation of the chromosomal anamolies.
a gamete nucleus has only half the number of chromosomes in it than a regular body cell. in humans a regular body cell has 46 chromosomes (23 pairs) in the nucleus, but a gamete ie sperm or egg cell has only 23 chromosomes, which are all unpaired. during fertilization the 23 chromosomes from a sperm and the 23 from the egg cell combine and pair up.
each skin cell has 46 chromosomes
In a "normal" human autosome (normal cell, not a sex cell), there is 23 pairs of chromosomes.
There are 23 haploid chromosomes in a normal human gamete (sex cell).
They have less chromosomes than a normal cell.
There are 46 chromosomes in the umbilical cord.
There are 23 haploid chromosomes in a normal human gamete (sex cell).
A normal human body cell has a total of 46 chromosomes. 23 chromosomes come from the mother and 23 chromosomes come from the father, totaling to 46 chromosomes in total.
There are 23 haploid chromosomes in a normal human gamete (sex cell).
Normal human gametes carry 23 chromosomes, which is half the number of chromosomes found in a somatic cell. During fertilization, a sperm cell with 23 chromosomes fuses with an egg cell, also with 23 chromosomes, to form a zygote with a total of 46 chromosomes.
A sex cell contains half the number of chromosomes found in a somatic (normal) cell. Therefore a human sex cell would contain 23 chromosomes.
A sex cell contains half the number of chromosomes found in a somatic (normal) cell. Therefore a human sex cell would contain 23 chromosomes.
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
