how many chromosomes are in a gene?

Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.

A gene is a stretch of DNA on a chromosome that has the instructions for making a protein. Each chromosome has many genes with humans having over 22,000 genes in all. A gene's instructions for a protein are written in the three letter code I referred to before. A protein is a molecular machine that does a specific job.

How many chromosomes do humans have? Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes.

The human genome is the genome of Homo sapiens. It is made up of 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 24 distinct human chromosomes: 22 autosomal chromosomes, plus the sex-determining X and Y chromosomes.

46 chromosomes forming 23 pairs of homologous chromosomes. length, centromere position, and staining pattern. The two chromosomes of a matching pair in which each chromosome carries genes controlling the same inherited characteristics. Two chromosomes of a homologous pair may have different versions of the same gene.

In humans, the Y chromosome spans about 58 million base pairs (the building blocks of DNA) and represents almost 2% of the total DNA in a male cell. The human Y chromosome contains over 200 genes, at least 72 of which code for proteins.

Genes are made of DNA. How many genes do humans have? Humans have 25,000 genes.

How many chromosomes do people 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.

Genes are subsections of DNA molecules linked together that create a particular characteristic. Each chromosome is made up of a single DNA molecule coiled around histone proteins. Research dating back to the 1800s shows that every living creature has a specific set of chromosomes in the nucleus of each of its cells.

Each chromosome contains numerous genes, which are the units of information. Every species of plant or animal has a specific number of chromosomes in each of its cells. Horses have 64 chromosomes. Cows have 60.

A quick overview of cell division The genetic information of plants, animals and other eukaryotic organisms resides in several (or many) individual DNA molecules, or chromosomes. For example, each human cell possesses 46 chromosomes, while each cell of an onion possesses 8 chromosomes.

Genes are passed from parents to children. Each person has 23 pairs of chromosomes, or 46 in all. For each pair, you get one chromosome from your mother and one chromosome from your father. About 1 in 150 babies is born with a chromosomal condition.

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.

The human genome is the genome of Homo sapiens. It is made up of 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 24 distinct human chromosomes: 22 autosomal chromosomes, plus the sex-determining X and Y chromosomes. Chromosomes 1-22 are numbered roughly in order of decreasing size.

Human chromosomes are located inside the nucleus of the cell. A chromosome is a structure that holds your genes. Your genes determine your traits, such as eye color and blood type. The usual number of chromosomes inside every cell of your body is 46 total chromosomes, or 23 pairs.
