  • Once it was realized that the sequence of bases in a gene specified the sequence of amino acids in a protein, various possibilities for such a genetic code were considered. How many bases are necessary to specify each amino acid? Is the code overlapping or nonoverlapping? Is the code punctuated or continuous?

  • Information Theory, Evolution, and the Origin of Life presents a timely introduction to the use of information theory and coding theory in molecular biology. The genetical information system, because it is linear and digital, resembles the algorithmic language of computers. George Gamow pointed out that the application of Shannon’s information theory breaks genetics and molecular biology out of the descriptive mode into the quantitative mode, and Dr. Yockey develops this theme, discussing how information theory and coding theory can be applied to molecular biology....

  • Inherited mitochondrial disorders are transmitted in a matrilineal fashion; all children from an affected mother will inherit the disease, but it will not be transmitted from an affected father to his children (Fig. 62-11D ). Alterations in the mtDNA affecting enzymes required for oxidative phosphorylation lead to reduction of ATP supply, generation of free radicals, and induction of apoptosis. Several syndromic disorders arising from mutations in the mitochondrial genome are known in humans and they affect both protein-coding and tRNA genes (Table 62-1 and Table 62-5).

  • Nucleotide Repeat Expansion Disorders Several diseases are associated with an increase in the number of nucleotide repeats above a certain threshold (Table 62-6). The repeats are sometimes located within the coding region of the genes, as in Huntington disease or the X-linked form of spinal and bulbar muscular atrophy (SBMA, Kennedy syndrome). In other instances, the repeats probably alter gene regulatory sequences. If an expansion is present, the DNA fragment is unstable and tends to expand further during cell division.

  • The Names of Plants is an invaluable reference for botanists and horticulturalists. The first section gives an historical account of the significant changes in the ways by which plants have been known and named. It documents the problems associated with an ever-increasing number of common names of plants, and the resolution of these problems through the introduction of International Codes for both botanical and horticultural nomenclature.

  • The human genome is largely made of complex sequences evolved over time due to replication,mutations and insertion of foreign DNA. Based on the nucleotide distribution and functional significance, the genome has been categorized into different block of sequences, namely genes or coding and non-coding regions. A special type of sequence located near genes, in relation to spread of DNA methylation and dinucleotide frequencies are the CpG islands1.

  • Over the past several years, scientists from the United States and around the world have been using a technique called DNA sequencing to unlock the genetic code of many different organisms. With code in hand, scientists can design sophisticated experiments that will inform our understanding of how an organism develops and functions. To date, they have carried out partial or complete DNA sequencing on human, mouse, rat, bacterial, and plant genomes. A major finding that was confirmed from these efforts is that most biologic functions are genetically conserved within and between species....

  • For purposes of deriving/identifying categories, references having to do with courtship, sex, pair-bonding, parenting, fidelity, mate guarding, and provisioning were initially targeted, along with themes related to long-term as well as short-term mating strategies. In the process of attempting to code the lyrics it became apparent that emotional expressions could be partitioned into different action references. For instance, “love” could either convey commitment, fidelity assurance, or a non-specific state. “Love” represents commitment when sung as “I love you.
