how many chromosomes does a nucleus have?

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

Humans are diploid organisms, carrying two complete sets of chromosomes in their somatic cells: one set of 23 chromosomes from their father and one set of 23 chromosomes from their mother. The two sets combined provide a full complement of 46 chromosomes.

Answer and Explanation: The cells of a human each contain 23 pairs of chromosomes, for a total of 46 chromosomes in all. It doesn't matter if it is a skin cell, a liver...

Some insects, for instance, only have one or two chromosomes. Meanwhile, giraffes have 62, chickens have 78, mice have 40, cabbages 18, and strawberries only 14. Humans, like many other species, are called 'diploid'.

Each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

A dog's body contains trillions of cells. Most of these cells contain a nucleus. In dogs, 38 pairs of autosomes (non-sex chromosomes) can be found in every nucleus, for a total of 76 chromosomes plus the two sex chromosomes (X and Y) for a grand total of 78.

The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.

Since each chromosome consists of one DNA molecule, each human somatic cell contains 46 chromosomes. A DNA molecule with part or all of the genetic material of an organism. Each of the two threadlike strands into which a chromosome divides longitudinally during cell division.

Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes.

Humans have 46 chromosomes, That number of chromosomes will be found a, in cells in anaphase. - : b. in egg and sperm cells. in somatic cells.

Chromosomes also contain chemical substances that govern the function of genes. The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells.

Mitosis is normal cell division. The cell will create a copy of it's DNA, resulting in 92 chromosomes temporarily in one cell, which will then split, creating two cells with 46 (23 pairs) chromosomes in them. If the cell then undergoes meiosis, it will be left with 23 chromosomes, unpaired.

Before mitosis starts, all the chromosomes in the nucleus replicate their DNA to make identical copies. The nucleus now contains two sets of replicated chromosomes, twice as many as a normal body cell.

Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid. The letter n is used to represent a single set of chromosomes; therefore a diploid organism is designated 2n.

The DNA sequences of homologous chromosomes are usually not exactly identical. The nuclei of most human cells contain 46 chromosomes. These 46 chromosomes consist of 23 pairs of homologous chromosomes, or homologs, meaning each of these pairs are alike, but not necessarily identical.

The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells. There are 22 pairs of autosomal chromosomes and one pair of sex chromosomes.
