my Doctor told me that there is DNA with one strand and there is with three and if i prove that he will award me so please help me

How many gene is present in one chromosomes?
A given gene is present on exactly two chromosomes in a somatic cell.
Are alleles made up of DNA?
All alleles contain DNA. They are the genes. An allele is one form of a gene. For example, the gene for flower color in pea plants has two alleles, one for purple flower color, and one for white flower color.
What structures make up chromosomes?
Gene is the functional unit of chromosome.
Why a species has homologous chromosomes?
Basically we are all made up from 50% mum and 50% dad. Chromosomes are a condensed version of our DNA; these chromosomes (DNA) contain the genes that tell our body what to do during development and throughout our lives. We have 23 chromosome pairs in total we get one chromosome from the mother and one from the father. The chromosomes are called homologous since each chromosome pair will contain the same genes on it but the genes will not necessarily code for the same thing. For example a chromosome will have the genes for eye color on it and since we have one from the mother and father we will have a pair of chromosomes with the gene with eye color on it. This would be a homologous chromosome pair, however one gene may say blue eyes the other may say brown eyes. The genes are still the same however each color would be a different allele for the gene.
What is X chromosome?
The x chromosome is one of the sex chromosomes, the other being the y chromosome. In mammals there are two of the sex chromosomes in each organism. Females generally contain two x chromosomes, and males contain one x chromosome and one y chromosome.
Gametes contain one half one quarter or is equal to the number of alles found in other cells in the body of an organism?
Gametes contain half of the number of chromosomes as somatic cells (the other cells of your body). These chromosomes have the same number of alleles on them as somatic cells, but gametes contain one allele of each gene while somatic cells contain two alleles of each gene. So, they contain half the amount of alleles that the rest of your cells do.

What is a homologies?
This are chromosomes that have exactly the same length that contain the same gene but those genes have different alleles.
Are alleles made up of DNA?
All alleles contain DNA. They are the genes. An allele is one form of a gene. For example, the gene for flower color in pea plants has two alleles, one for purple flower color, and one for white flower color.
What structures make up chromosomes?
Gene is the functional unit of chromosome.
What is the primary function of the chromosome?
Chromosomes contain DNA that provides a "blueprint," or genetic information, for the organism.
Why do the chromosomes in a homologous pair differ from one another?
They have the same length and gene locus but differ in terms of alleles. An allele is a form of a gene, differing from other alleles of the gene by a few bases at most and occupying the same locus as the other alleles of that gene. The gene locus is the position of a gene on a chromosome. Hope that helped! They have the same length and gene locus but differ in terms of alleles.

Genes are found on which part of a cell?
Genes can be found in chromosomes. The cell nucleus of almost every cell contains chromosomes and genes. They contain the DNA and the gene shows as a section of the DNA.

What is the relationships between chromosomes genes and alleles?
alleles are the various types of options that is chosen by the gene. The gene is the segment of DNA that codes for the protein. Genes are found on chromosomes. Chromosomes contain multiple genes.
Does DNA contain 23 chromosomes?
No. DNA doesn't contain chromosomes. Chromosomes are DNA.
How many chromosomes do they contain?
Bacteria contain one circular chromosome (and several tiny circular plasmids), some slime molds contain hundreds of thousands of linear chromosomes. Other organisms contain various numbers of chromosomes depending on the species.
