Does humans have nucleus?
The nucleus is the control center of the cell, and as all living things are made up of cells, all living things have AT LEAST on nucleus. Humans are made up of trillions of cells, therefore they have trillions of nuclei. However, one does not normally measure a species by nuclei. Animals with one nucleus would be so small, you need microscopes to see them, and strong ones at that.
What animal has a nucleus?
Most animal cells (except for human red blood cells and some others) have a nucleus. It is like a control centre in the cell which allows some substances to enter and others substances to leave the cell. It also initiates chemical reactions and processes like respiration in the cell cytoplasm.
Is there a cell in humans that don't have DNA?
No. Not all cells have a nucleus, which contains nuclear DNA; but all cells have mitochondria, which have their own DNA, called mitochondrial DNA, or mDNA. In humans, the cells that lack a nucleus and therefore nuclear DNA, are mature red blood cells, but they do have mitochondria and mitochondrial DNA.
What are some fast facts about the nucleus?
Here are some quick ones off the top of my head: * The nucleus is a membrane-bound organelle inside all eukaryotic cells * It contains most of the genetic material (DNA) of the cell (the rest is stored in mitochondria) * All eukaryotic cells contain a nucleus by definition; the word comes from the Greek "eu" (true) and "karyon" (nut), which refers to the nucleus * Some cells of eukaryotic organisms (eg, humans) do not contain cells; for example, red blood cells are without a nucleus * DNA replication and transcription occur within the nucleus; transcribed RNA leaves the nucleus via nuclear pores * Ribosomes are made within the nucleolus, a structure found within the nucleus
What is the diploid number of chromosomes in humans and how is it identified?
The diploid number of chromosomes in humans is 46. This is identified by counting the number of chromosomes in a cell's nucleus, which contains two sets of chromosomes - one set from each parent.
Where do humans have 3 billion base pairs?
Humans have approximately 3 billion base pairs in their DNA, which is found in the nucleus of every human cell. This DNA contains the genetic information that determines an individual's traits and characteristics.
Do humans have a cytoplasm?
No, humans do not have cytoplasm. Cytoplasm is a jelly-like substance found inside cells that contains various organelles. Humans have cells that contain cytoplasm, but as a whole organism, humans do not have cytoplasm.
Is the nucleus found in all cells?
No. Every living cell of animals, plants, and other eukaryotes contain a single nucleus -- that, in turn, contains the DNA. However, about a quarter of the human cells in the human body are red blood cells, which do not contain a nucleus or DNA. Also, the cells of bacteria and other prokaryotes contain DNA, but do not have a nucleus. (Here "nucleus" implies "biological nucleus", a single organelle inside the cell that contains the DNA. Atomic physicists use the word "nucleus" differently, the clump of protons and neutrons at the center of each atom. Every cell contains water, DNA, and other molecules; the molecules are composed of atoms which each have an atomic nucleus, so there are typically trillions of atoms and therefore trillions of atomic nuclei in each cell).
Can you give me a sentence using nucleus in biology form?
Humans contain a nucleus in our body.
Is the nucleus found in animals or in humans?
Both
Number of chromosome observed in each nucleus of the cells in animal mitosis model?
During animal mitosis, each nucleus contains a diploid number of chromosomes. This means that each nucleus in the cell will typically have two sets of chromosomes, with one set inherited from each parent. In humans, for example, this would mean that each nucleus contains 46 chromosomes (23 pairs) during mitosis.
