Creating a Miniature Factory. Expanding the Genetic Code. At the Scripps Institute in California, scientists have engineered a bacterium with an expanded genetic code.. In addition to A, T, G, and C, they have . tree. The . geneticists studying the alien organisms have deciphered their genetic code. For familiarity, they have used A, C, G, and T to indicate the bases in this code..  . A comparable genetic sequence in each alien has been identified in the genes that code for eye growth. This genetic sequence has allowed the aliens to be divided into six groups, with the single-tail, three-eye group split in half. The geneticists also studied several outgroup species (not shown) to compile a likely ancestral DNA sequence. From this information, they have constructed four possible phylogenetic trees..

Mitotic and meiotic divisions are highly precise as a result of which the chromosome number of different species are highly stable. But a low frequency of irregularities do occur. These irregularities in chromosome number (some type) have contributed to crop evolution and (all the types) are of much use in plant breeding.. Professor of Sericulture. Yuvaraja’s. College, .

Therefore, germplasm collection is a collection of a large number of genotypes of a crop species and its wild relatives. .
