Know your chromosomes

We continue the series with a discussion on family trees or pedigree analysis and the mapping of genus through linkage studies.     

Know your chromosomes

The pattern of inheritance of genes linked to the sex chromosomes in humans have their own signature due to the presence of a single copy of X and Y chromosomes in males and 2 copies of the X chromosome in females. However nature has adopted ingenious methods to equalize the copy number of most genes that map to the X chromosome. This in turn has contributed to the understanding of regulatory phenomena involving whole chromosomes.     

Know your chromosomes

The selective elimination of human chromosomes in mousehuman hybrid cells generates a unique system for cytogenetic analysis. The use of such somatic cell hybrids in chromosome mapping is discussed in this part of the series.     

Know your chromosomes

Mutations are vital in deciphering the regulated expression of genes in all organisms. In humans, study of mutant traits has helped in the management of genetic disorders. This article focuses on the nature of mutations that are encountered in general and the possible ways in which these mutations are produced.     

Know your chromosomes

In this article, the last of the series, the implications of understanding our genome in its totality are examined. The concerns raised seem as important as the gains promised.     

Know your chromosomes

The study of cellular structures including chromosomes began as early as the 17th century. The organization of chromosomes, the structure and function of genes and the role of genetic mutations in diseases continue to be an area of intense scientific investigation.
