Up to now in your studies, you have been learning the normal features of human beings (i. Now it is time to introduce you to the abnormalities that can occur in humans i. General pathology covers the basic mechanisms of diseases whereas systemic pathology covers diseases as they occur in each organ system. Most of these topics represent the major categories of diseases that can occur in different organ systems. For example, acute inflammation can occur in different organs but wherever it occurs its mechanism is the same. That is, an acute inflammation in the skin has the same mechanisms & features as an acute inflammation of the meninges. Therefore, if one knows general pathology well, one can apply this knowledge to diseases in the various organ systems. Hence, your general pathology knowledge will facilitate your understanding of systemic diseases (Systemic Pathology). Therefore, the whole purpose of general pathology is to help you understand systemic diseases i. So, even though, you will understand the basic mechanisms of diseases common to various types of illnesses, it doesnt mean that this book has covers all of pathology in as much as it didnt cover systemic pathology. Therefore, after reading this book, you are encouraged to read books on systemic pathology.
In paracentric inversion buy bisoprolol 5 mg with visa, the inverted segment of the chromosome has no centromere cheap bisoprolol 10mg on line. When translocation occurs between two non-homologous chromosomes, then it is called reciprocal translocation or illegitimate crossingover. In heterozygous translocation, one member of each pair of chromosomes is normal and the other member is with interchanged segment. But in homozygous translocation, both the members of paired chromosomes have translocated segments. Numerical chromosomal aberrations Each species of an organism has a specific number of chromosomes in its somatic cells. Alterations in the number of chromosomes from the diploid set is called numerical chromosomal aberration. Euploidy Euploidy is the variation in the chromosome number that occurs due to increase or decrease of full set of chromosomes. Diploidy In most of the plants and animals, the somatic cells contain two sets of chromosome. Polyploidy Addition of one or more sets of chromosomes to the diploid set results in polyploidy. Watermelon, grapes and banana are autotriploids, whereas apple is an autotetraploid. Allopolyploidy Increase in one or more haploid set of chromosomes from two different species result in allopolyploidy. It is obtained by crossing a wheat Triticum durum (2n = 4x = 28) and a rye Secale cereale (2n = 2x = 14). Then the chromosome number is doubled using colchicine and it becomes an hexaploid. Parent Triticum durum x Secale cereale 2n = 28 2n = 14 (2n = 4x = 28) (2n = 2x = 14) F hybrid (sterile)1 2n = 21 (2n = 3x = 21) Chromosome doubled (Colchicine treatment) 2n = 42 (2n = 6x = 42) Hexaploid Triticale 129 Aneuploidy Variation that involves one or two chromosomes within the diploid set of an organism results in aneuploidy. Hypoploidy Decrease in one or two chromosomes from the diploid set is described as hypoploidy. Nullisomy is the condition in which a pair of homologous chromosomes is lost from the diploid set i. Hyperploidy Addition of one or two chromosomes to the diploid set of chromosome results in hyperploidy. Trisomy results due to the addition of one chromosome to diploid set of chromosomes. Tetrasomy results due to the addition of two chromosomes to diploid set of chromosome. Significance of ploidy m Polyploidy plays an important role in plant breeding and horticulture. R-type cells S-type cells Heat killed S-type cells Heat killed R-type cells S-type cells Fig. The virulent strain synthesized a smooth polysaccharide coat and produces smooth colonies. Another strain which lacked the proper polysaccharide coat is harmless and produces rough colonies. Griffith killed some smooth strain bacteria and mixed it with live rough strain bacteria. When the mixture of heat killed S-type cells and R-type 132 cells was injected into the mouse, the mouse was dead. That is the hereditary material of heat killed S-type cells had transformed R-type cells into virulent smooth strains. They are complex macro molecules and made up of millions of smaller units called nucleotides. Each nucleotide is G C made up of pentose sugar, a A T phosphate group and a nitrogenous base. T A Adenine and guanine are the purines C G and thymine and cytosine are pyrimidines. T Thymine The sub-unit containing only sugar G C and nitrogenous base is known as A T nucleoside. They are adenine nucleotide, guanine nucleotide, thymine nucleotide and cytosine nucleotide. There are two hydrogen bonds between adenine and thymine (A= T) and there are three hydrogen bonds between guanine and cytosine (GC) pairing. The enzyme helicase unwinds the two strands and as a result replication fork is formed. Now we will know more about their types and their role in the biology of an organism. The type of gene that is involved in protein synthesis depends upon their length, kinds and sequence of nucleotides.
