10.4 Structure and Function of Cellular Genomes

WebGenes come in pairs (that is, are present in two copies in an organism). Genes come in different versions, now called alleles. When an organism has two different alleles of a gene, one (the dominant allele) will hide the presence of the other (the recessive allele) and determine appearance. WebGenes are composed of deoxyribonucleic acid ( DNA ), except in some viruses, which have genes consisting of a closely related compound called ribonucleic acid ( RNA ). A DNA …

WebEukaryotic organisms express a subset of the DNA that is encoded in any given cell. In each cell type, the type and amount of protein is regulated by controlling gene expression. To express a protein, the DNA is first transcribed into RNA, which is then translated into proteins. In prokaryotic cells, these processes occur almost simultaneously. WebHumans typically have 46 chromosomes in each cell of their body, made up of 22 paired chromosomes and two sex chromosomes. These chromosomes contain between 20,000 and 25,000 genes. New genes are being identified all the time. The paired chromosomes are numbered from 1 to 22 according to size. (Chromosome number 1 is the biggest.)
