What is a chromosome? Information about chromosomal

Cells in the core, during cell division in certain ways and basic dyes can be painted dark fibrous structures. There are many types of DNA and protein in the composition is. Nükleoprotein structure of the unit. These are the growth of a vibrant, growth and inheritance of the genes carry design features. Genes are DNA structure. DNA to carry genetic information mesüldür. Fixed number of chromosomes in cells of the type discussed will be found. Peas in 14 chromosomes per cell, 46 in human cells, the bowel worm 4, the 32 honey bee, mouse, 40, cattle 60, 48 in potatoes, corn on the 20, frog 26, 30 in the grasshopper, vinegar fly 8'er the chromosome is found in cells. This number is indicated by 2n. Diploid was named. 2n = 46'dır for man.

Chromosomes, cells in the kernel of the rest of the circuit to be seen with light microscopy are found in the form of very fine network during cell division as tight as thick as a spread. This circuit is painted with some paint can be seen with light microscopy. Chromosome length of 2-6 microns, the diameter is 0,2-2 microns. Size is fixed for each type of chromosome. For example, the length of human chromosomes is 4-6 microns.

Each member of the chromosome number, shape and size that provides karyotipini. Karyotip, from insemination to fertilization and species are protected, but its properties will continue. Chromosome maps of some species based on Karyotipe has been removed. Chromosomes, proteins, and a case "matrix" of the test substance within a search is made of at least two yarns. Each of these threads "kromatid" is called. Research, and two or more of this thread from the thread that has been made. Kromatidleri constituent yarns, "kromonema" or "kromomer" or "chromatin fiber" is called. On this iplikciklerin "Kromomer" or "chromatin of them" includes swelling of the experiment. Many of chromatin, the structure will move in the genes.

Each chromosome in cells of the body that produce sexual live from the two types are available. That one of their members from the other parent has received from his father. In terms of form and structure are similar to each other, from one home to another chromosome from the father-in "homologous chromosomes" is called. Even in body cells diploid number of sexual canlıların (2n) chromosome, but found, in the haploid germ cell (n) number of chromosomes will be found. To keep constant the number of chromosome types of sex cells, mature ago mayoz (meios) by dividing through (2n) to half the number (n) is reduced. Mayoz only appears in the sex cells.

Human body cells in 23 pair (46 pieces), one chromosome 23 is found only in reproductive cells. Fertilization is the result hasıl oosperm, female (n) and man (n) as the number of chromosomes (2n) number is reached. Thus, the number of protected species would be hard chromosomes. In human sperm cells (in men) n = 23, egg cells (in female) n = number of chromosomes is 23. Sex chromosomes are: always a pair of chromosomes determines gender. They also are called sex chromosomes. The rest of the chromosomes are mapped geminate otozomal. X and Y sex chromosomes that are two types. Dişilik X, Y chromosome is the male sex. Y chromosome, X chromosome to the dominant (domanant) capability. Pair of sex chromosomes in XX female, XY for men is the. To X and Y sex chromosomes "gonozom" or "hetero-chromosomes" is called. chromosome of human body cells formula: 2n-=. 46 is. 44 of them female individuals and 2 of them otozom one gonozom (XX), males in the 44 otozom and 2 gonozom (XY) will be found. Then the female individuals of the diploid number of 2n = 44 + XX chromosomes and men can be expressed as 2n = 44 + XY. Others live in this rule will apply. Drosaphila'nın (vinegar fly) 2n = 6 + XX in females, in males is 2n = 6 + XY.

Sex cells, dividing the result mayoz number of chromosomes is reduced to half, (n) number of chromosomes they carry. X sex chromosome of the female egg cell always has. Half of men in the number of X sperm cells, the other half of the Y chromosome is found. human reproductive cells in the female chromosome formula (egg cell) n = 22 + X, men's sperm cells, or n = 22 n = 22 + X + Y'dir.

That is to say, men in terms of gender are two different sperm. n = 22 + X chromosome with the dişilik, n = 22 + Y as the male sex characteristics will move. Egg cells of the female is always n = 22 + X will always show dişilik features.

X chromosome, a sperm, the fertilized egg cell, the 2n = 44 + XX will oosperm female cub was born. With a Y chromosome sperm egg fertilization occurs is 2n = 44 + XY oosperm. Y is dominant X chromosome is male cub. As you can see the determination of sex depends on sperm from men. Nevertheless, it is not enough information in this regard by the people, as unfair in some regions women boy is asked to bear. Even men are not born of women who divorce are also common.

hereditary diseases in humans are connected to X and Y'ye, For example, myopic, color blindness, hemophilia gene inheritance of X is connected. The second and third toes of boys swimmer of the Y chromosome with birds occur, such as curtains moved. Create many of the inner ear lulh with the Y chromosome from father to son moved. This feature is not never girls. Each character is designated by at least two genes. Genetic science is represented by a letter in her genes. Dominant (dominant) genes capitalized, recessive (çekinik) genes with the same letters rilir small.

The chromosomal disease: Some cases mayoz (-=- meiosis) chromosomes divide equally in the cell does not go. Therefore, individuals born with the new show deviations in the number of chromosomes is 2n. This situation is considered state of disease. Turner, who has the disease in females only one X-chromosome is found. (45X0) as shown. Gender development is corrupt, boy short, are obese and infertile. Men with M linefelter bozukItığuna X and one Y chromosome has two. (47XXY) is expressed as. These fine voice, sparse beard, internal reproductive organs are small, are retarded.

In rare cases XXX, XXXY, XXXXX, is found in individuals with sex chromosome XXXXY. In this case the X chromosome, regardless of the number of individuals carrying the Y chromosome is male. Genetic features between generations from parents to son in the core of germ cell chromosome is passed through. Rather the chromatin array in the chromosome of kromonema yarn contained in one of the genes moved. Genes are DNA structure. Then the DNA molecule of hereditary features and is passed between generations. DNA molecules themselves on the match, so have the ability to copy.

Parents of the DNA molecule, the transferred cells to produce copies of the hereditary encryption, son of the features play a role in switching. Indicated by short DNA deoksiribo nucleic acid, the core of the cell chromosome in which the hereditary basis for discrimination. Has all the qualities of the previous live. Mom and Dad are hidden in the DNA of some hususiyet. Every soul has its own DNA molecules in bulunur.Hurma orange tree does not grow, does not bear cub at a cow, monkey, human, monkey, does not occur all the people in these DNA molecules is of hususiyet.

Various information and various people in our brain are official. If they ever see one of our brain to open is not possible. Speaking of the place we 'is. Out that information from a Teyb band, I can not understand unless it is a tape. DNA can be likened to the band's teyb. doludıır inside with water. Even the most intelligent one, DNA is helpless in-ten to know the secret of life. Canlıların characters (in the blue-eyed, curly-haired worth, swarthiness, fairness, slant of eyes, etc.) a lifeless molecules, and the encryption of the molecule itself automatically to match, the characters from generation to generation transfer, expressed more clearly with a secret life of carrying Sayani amazed.
