Biology is the science discipline that studies life processes or characteristics of living organisms, including their structure, function, growth, origin, distribution and evolution. Creation biology is basically the study of biological systems under the inference that God created life on Earth with a finite number of discrete created kinds or baramin. While these forms of life have the ability to vary, and even undergo speciation, they cannot arise spontaneously from non-life, cannot interbreed outside of their kind, and cannot increase in genetic complexity.

DNA

Deoxyribonucleic Acid (DNA) is the molecular substance used to encode heritable information in all living cells. In eukaryotic cells, DNA is contained in a membrane-bounded region called the nucleus. It exists in long strands called chromosomes. The number and length of chromosomes differs among organisms.

The information is divided into discrete units called genes, which when activated send out instructions specifying cellular machinery to assemble proteins. This process called gene expression is needed to build and maintain all biological systems. The instructions contained within genes consist of a code with rules of syntax comparable to those found in the written language. In the DNA code, the gene is much like a sentence that contain "words" (triplets of nucleotides) known as codons.

A typical human cell contains a total of 46 chromosomes and about 6 × 109 nucleotides. To understand the data compression involved in this form of information, the amount of DNA in cell could in theory be packed into a space about 1.9 cubit micron in size. By comparison, 6 x 109 letters in a book would occupy more than a million pages, thus requiring more than 1017 times as much space.[1]

Harold W. Clark

Harold Willard Clark (1891-1986) was a Berkeley-trained biologist and a former student of George McCready Price who later replaced him on the faculty of Pacific Union College in 1922. Clark ultimately taught biology at Seventh-Day Adventist colleges for thirty-five years. Clark was a young earth creationist, who published his first book in 1929 (Back to Creationism) in which he urged readers to quit simply opposing evolution and to adopt the new "science of creationism". The term "creationism" subsequently became popularly used by scientific creationists to describe their distinctive interpretation of earth history.

"The origin of the [genetic] code is perhaps the most perplexing problem in evolutionary biology. The existing translational machinery is at the same time so complex, so universal, and so essential that it is hard to see how it could have come into existences or how life could have existed without it. The discovery of ribozymes has made it easier to imagine an answer to the second of these questions, but the transformation of an 'RNA world' into one in which catalysis is performed by proteins, and nucleic acids specialize in the transmission of information, remains a formidable problem." - Maynard Smith J. & Szathmary E., "The Major Transitions in Evolution," W.H. Freeman: Oxford UK, 1995, p81.[1]
