- A chromosome (chromo- + -some) is a packaged and organized structure containing most of the DNA of a living organism.exually reproducing species have somatic cells (body cells), which are diploid [2n] having two sets of chromosomes (23 pairs in humans with one set of 23 chromosomes from each parent), one set from the mother and one from the father. Gametes, reproductive cells, are haploid [n]: They have one set of chromosomes.

Definitions &Translations A chromosome is an organized structure of DNA and protein that is found in nucleus of the cell. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.

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. Segments of DNA in specific patterns are called genes. Your genes make you who you are.

Chromosomes: Definition & Structure Chromosomes are thread-like molecules that carry hereditary information for everything from height to eye color. They are made of protein and one molecule of DNA, which contains an organism’s genetic instructions, passed down from parents. In humans, animals, and plants, most chromosomes are arranged in pairs within the nucleus of a cell. Humans have 22 of these chromosome pairs, called autosomes. How sex is determined. Humans have an additional pair of sex chromosomes for a total of 46 chromosomes.

Chromosome A chromosome (chromo- + -some) is a packaged and organized structure containing most of the DNA of a living organism.his gives 46 chromosomes in total. Other organisms have more than two copies of their chromosome types, such as bread wheat, which is hexaploid and has six copies of seven different chromosome types – 42 chromosomes in total.

Sex chromosome Definition. noun, plural: sex chromosomes. A type of chromosome in the genome that is involved in the determination of the sex as well as the development of sexual characteristics in an organism. It occurs in pairs in somatic cells while singly in sex cells . Supplement

- If someone has an extra chromosome it means there was a genetic  mutation that is abnormal in human development. It may result in  problems with the person affecting them on… a basic level, or may go  fully unnoticed. A common disorder that can be caused by having an  extra chromosome is Down's Syndrome.

What is a chromosome? DNA and histone proteins are packaged into structures called chromosomes. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing.However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope.hromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing.

What Does It Mean When Your Baby Is Born With An Extra Chromosome? The chromosomes in the 23rd pair are called the SEX CHROMOSOMES. Sex chromosomes are labelled X or Y. Males normally have one copy of the X chromosome and one copy of the Y chromosome in each cell; it is the Y chromosome that determines maleness.

Difference Between Gene and Chromosome Chromosome is an organized structure in cells containing a long, coiled, and single strand of DNA with some associated proteins. A chromosome is a long DNA strand or molecule that includes a number of genes, regulatory elements, and nucleotide sequences.herefore, it could be said that chromosomes are longer and larger than genes. • Chromosomes carry genes but not the other way around. • Gene is composed of only serially connected nucleotides while chromosome has nucleotides and proteins in the structure.

What Does Chromosomes Mean? Every species has a characteristic number of chromosomes; humans have 23 pairs (22 pairs of autosomal, or nonsex, chromosomes and one pair of sex chromosomes). Human chromosomes consist primarily of DNA. During cell division (see meiosis, mitosis), chromosomes are distributed evenly among daughter cells. In sexually reproducing organisms, the number of chromosomes in somatic (nonsex) cells is diploid, while gametes or sex cells (egg and sperm) produced by meiosis are haploid (see ploidy).
