Chromosome walking
Chromosome walking is a technique to clone a gene (e.g., a disease gene) from its known closest markers. The closest linked marker (e.g., EST or a known gene) to the gene is used to probe a genomic library.

Chromosome walking is a method in genetics for identifying and sequencing long parts of a DNA strand, e.g., a chromosome.
Chromosome Numbers
All animals have a characteristic number of chromosomes in their body cells called the diploid (or 2n) number.

A chromosome is an organized package of DNA found in the nucleus of the cell. Different organisms have different numbers of chromosomes.
Chromosomes - Pull up Those Genes
Chromosomes are the things that make organisms what they are. They carry all of the information used to help a cell grow, thrive, and reproduce. Chromosomes are made up of DNA.
The Y chromosome contains a gene called SRY (for sex-determining region of Y).

Cloning a Disease Gene by Chromosome Walking.
After a marker is linked to within 1 cM of a disease gene, chromosome walking can be used to clone the disease gene itself.
Chromosome Abnormalities (e.g. Down syndrome)
Another type of human genetic disorder involves chromosome abnormalities.
chromosome replication - chromosome replication takes place during S phase of the cell cycle; the two strands of a DNA double helix separate and each serves as a template for synthesis of complementary daughter strand.
Chromosome: a self-replicating genetic structure, composed primarily of proteins and DNA, which carry nucleotide sequences known as genes.
chromosome -- Linear piece of eukaryotic DNA, often bound by specialized proteins known as histones.
Chromosome (KROH-muh-sohm) A cellular structure containing genes. Excluding sperm and egg cells, humans have 46 chromosomes (23 pairs) in each cell.
Chromosome
A self-replicating DNA molecule that carries essential genetic information for growth and replication of a cell or virus.
Chromosome The structure which is built up around each nuclear DNA molecule. It is comprised of a single (double stranded) DNA molecule with associated histone proteins, non-histone proteins and RNA.
Chromosome. A single DNA molecule, a tightly coiled strant of DNA, condensed into a compact structure in vivo by complexing with accessory histones or histone-like proteins. Chromosomes exist in pairs in higher eukaryotes. (See Chromosome walking.

chromosome theory of inheritance Holds that chromosomes are the cellular components that physically contain genes; proposed in 1903 by Walter Sutton and Theodore Boveri.
Chromosome: A linear sequence of genes wound up with proteins into a single unit that is found in the nucleus of cells. See also DNA, genes.
chromosome
[Gk. chroma, color + soma, body]
A threadlike, gene-carrying structure found in the nucleus. Each chromosome consists of one very long DNA molecule and associated proteins. See chromatin.

chromosome
a long, threadlike association of genes in the nucleus of all eukaryotic cells and most visible during mitosis and meiosis. Chromosomes consist of DNA and protein.
Chromosome: Structure in a cell nucleus that carries the genes. Each chromosome consists of one very long strand of DNA, coiled and folded to produce a compact body. They become more compact and visible during metaphase of cell division.

Sex chromosomes: The X and Y chromosomes in human beings that determine the sex of an individual. Females have two X chromosomes; males have one X an d one Y. Single strand: One half of a DNA double helix.
Chromosome walking
Method involving hybridizing a primer of known sequence to a clone from an unordered genomic library and synthesizing a short complementary strand (called walking along a chromosome).
Chromosome
The term was proposed by Waldeyer (1888) for the individual threads within a cell nucleus (gk. chroma, colour; soma, body).
Chromosome
- Components in a cell that contain genetic information. Each chromosome contains numerous genes. Chromosomes occur in pairs: one obtained from the mother; the other from the father.
chromosomes - structure composed of a very long DNA molecule and associated proteinsthat carries part (or all) of that hereditary information of an organism.
Chromosomes are divided into genes, each gene being a stretch of DNA, i.e., a sequence of nucleotides (A,G,C,T for short). The location of a gene is called a locus. (The position of a nucleotide within a gene is called a site.
CHROMOSOME WALKING - The sequential isolation of clones carrying overlapping sequences of DNA which span large regions of a chromosome. Overlapping regions of clones can be identified by hybridization.
Chromosome walking: A technique for cloning everything in the genome around a known piece of DNA (the starting probe).
chromosome Rodlike structure that appears in the nucleus of a cell during mitosis; contains the genes responsible for heredity.
Sex chromosomes are a relatively recent invention. Our ancestors in the tree of evolution did not have two sex chromosomes that are fully differentiated the way we know them with an X and a Y chromosomes.
polytene chromosome - large chromosome resulting from repeated DNA replication and alignment of homologs in the absence of mitosis; found in salivary glands and some other tissues of dipteran insects.
Alternate forms of a gene or DNA sequence, which occur on either of two homologous chromosomes in a diploid organism. (See DNA polymorphism.) Alternative mRNA splicing. The inclusion or exclusion of different exons to form different mRNA transcripts.

DNA usually occurs as linear chromosomes in eukaryotes, and circular chromosomes in prokaryotes. A chromosome is an organized structure consisting of DNA and histones.
Prophase: During this first mitotic stage, the nucleolus fades and chromatin (replicated DNA and associated proteins) condenses into chromosomes. Each replicated chromosome comprises two chromatids, both with the same genetic information.
