Plant RNA viruses show a wide variation in their genome structure and organisation and may have different terminal structures such as cap structures or genome-linked proteins (VPg) at the 5' end, and a poly(A)-tail or tRNA-like structure at the 3' end of their RNA (reviewed by Goldbach et al., 1991).

Genomes are evolutionarily dynamic and analysis provides insights Mitochondria and chloroplast structure and genome organisation. With a large number of prokaryotic and eukaryotic genomes completely sequenced and more forthcoming, access to the genomic information and synthesizing it for the discovery of new knowledge have become central themes of modern biological research. The proportion of unique DNA varies in different eukaryotic organisms (Table 4). Genome Organization at the DNA Level. 1.Human C3 and C5 structural genes are located on chromosome 19p13.3-p13.2 and 9q33, respectively [30, 31].Although C3 (41 kb) and C5 (79 kb) genes are quite different in size, their intron-exon organization is very similar, with each consisting of 41 exons [7, 11].

The cell is the structural and functional unit of all living organisms, and is sometimes called the “building block of life.” Some organisms, such as bacteria, are unicellular, consisting of a single cell. Nuzzled. 10/30/19 Viruses are categorized into over 30 distinct groups which are classified as families and genera. Vectors of Plant Viruses . • The diseases caused by the major coronaviruses are listed. In many plant species with relatively large genomes, chromosomes during interphase adopt Rabl configuration (Cowan et al., 2001).This term describes an interphase chromosome arrangement in which centromeres and telomeres are located at opposite sides of the nucleus ().This configuration is thought to be a remnant of a preceding anaphase. Curr Opin Biotechnol. Ø DNA in the chromatin attain a packing ratio of about 7:1 (seven fold packing) by the formation of nucleosomes.. Ø Nucleosome units organized into more compact structure of 30 nm in diameter called 30 nm fibers (proposed by Rachel Horowitz & Christopher Woodcock in 1990).. Ø The H1 histone plays very important role in the formation of the 30-nm fiber.
