The test results are not preexisting conditions, but the probablitlity of getting those diseases. Share Your PDF File Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Genes are composed of DNA, they are the units of inheritance and they specify particular proteins, Distinguish between Mendelian trait and multifactoral trait, Mendelian traits are determined by one gene, Distinguish between genomics and proteomics, Genomics is the new field of investigating how genes interact and comparing genomes Meanwhile, an asymmetric karyotype is a karyotype showing a large difference between the smallest and largest chromosomes of the set. In most cells, chromosomes are located in functional pairs in the nucleus. The benefit would be that people could access the information easier, the danger would be that anyone might be able to find the information. Moreover, an increased asymmetric karyotype is associated with specialized zygomorphic flowers. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet.

Each of these cells contains a nucleus. Genes are the building blocks for your body. The coordination of various functions is brought about through the formation of enzymes, which are complex protein molecules. -CODON Genome size refers to the amount of DNA contained in a haploid genome expressed either in terms of the number of base pairs, kilobases (1 kb = 1000 bp), or megabases (1 Mb = 1 000 000 bp), or as the mass of DNA in picograms (1 pg = 1012 g). DNA constantly replicates itself by making hand-written copies of your bodys instruction manual using the chunks of bases that form the words.
