Klinefelter's Syndrome: Causes & Symptoms ||Class 12 Biology

By -
  Klinefelter's syndrome is a sex chromosomal abnormality. It occurs due to the presence of an additional copy of X chromosome resulting in the karyotype of 47, XXY.
  The syndrome was named after American endocrinologist Harry Klinefelter's in 1942, who described about it.
  Klinefelter's syndrome occurs randomly. An older mother may have a slightly increased risk of a child with Klinefelter's Syndrome. It is one of the most common chromosomal Disorders, occuring in 1-2 per 1,000 live male birth.
  Affected individuals are sterile male. Individuals have masculine development but feminine development (development of breast, i.e., gynaecomastia) also occurs. Sometimes symptoms are more prominent and may include weaker muscles, poor coordination, less body hair and undeveloped testes. 
  There is no cure for Klinefelter's syndrome, a number of treatment may help. Physical therapy, counseling, speech and language therapy may be useful.

Spermatogenesis : Definition & Process ||Class 12 Biology

By -
Image
    Spermatogenesis is the process of formation of spermatozoa (sperms) in the testes which originate from the primordial germ cells (PCGs).     The process of Spermatogenesis initiates at puberty and continues even in the old age.       The process of Spermatogenesis comprised the following two main stages- 1. Formation of spermatids 2. Spermiogenesis 1. Formation of spermatids : It include the following three phases- i) Multiplication Phase ii) Growth Phase iii) Maturation Phase   i) Multiplication Phase : During this phase, the immature germ cells present in the Seminiferous tubules of the testes known as spermatogonia increases in number by mitotic divisions and so that the newly formed spermatogonium possesses the same number at chromosomes.  ii) Growth Phase : Each spermatogonium is diploid (2n) and contains 46 chromosomes. Some of the spermatogonia called primary spermatocytes.  iii)  Maturation Phase : Primary spermatoc...

Sperm: Structure ||Class 12 Biology

By -
Image
     A mature spermatozoa or a sperm cell is a microscopic, tadpole-shaped structure of about 2-5 micrometer in diameter and 50 micrometer long. A plasma membrane encloses the whole body of sperm.      Sperm consists of head, neck, middle piece and tail.       1. Head: It is flat, oval and composed of a large haploid nucleus and a small cap-like structure called acrosome. It lies at the tip of the nucleus and is formed from the Golgi complex. It contains hydrolytic enzymes and is used to contact and penetrate the egg (ova) during fertilization.       2. Neck: Neck is the smallest part, it is short structure that contains two centrioles- one parallel to the base of the nucleus and called proximal centriole and other distal centriole perpendicular to the previous one. The proximal centriole enters into the egg during fertilization and starts the first cleavage division of the egg which has no centriole. The distal centriole give...

Antibody: Structure ||Class 12 Biology

By -

      Antibodies are immunoglobulin (Ig)  molecules. An Antibody seems like a Y-shaped structure. Antibodies are of mainly 5 types such as, IgA, IgM, IgE, IgG and IgD.       Antibodies are glycoproteins. They are typically made of basic structural units that consists of four polypeptide chains: two identical large heavy (H) chains and two identical small light (L) chains connected by disulphide bonds. Hence, an Antibody is represented as H 2 L 2 . The size of an antibody molecule is about 10nm. Each of the four chains has two regions: the constant region and the variable region.         The antibody recognizes a unique molecule of the pathogen, called an antigen via fragment antigen-binding (Fab) site of variable region. An antigen binding site is also called paratope, is a part of an antibody which recognizes and binds to an antigen. The part of antigen to which the paratope binds is called an epitope. The ability of an antibody to...
