Deoxyribonucleic Acid (DNA) is at the heart of all life. It is in every cell and it carries the information for the construction of that life form. It can be viewed as being a long chain consisting of four different types of links, chemically known as nucleotides. The DNA of single cell species like bacteria, contain about 600,000 nucleotides, whereas human DNA has over 3,000,000,000. DNA does not comprise one long chain but it is in bundles called chromosomes. The chromosomes are in pairs and different life forms have different numbers of chromosomes and only life with the same number of chromosomes can produce viable off spring. For example, humans have 23 pairs chromosomes, primates have 24.
DNA does not consist as long strands but as double strands twisted into what has been called a double helix with weak bonding between the two strands. It can be imagined as railway tracks being pulled up and twisted as shown in the diagram.
DNA confirms the Bible
In the beginning God created the heavens and earth and all life (Genesis chapter 1)
In DNA the arrangement of the nucleotides (links) give it the ability to contain information, just like the arrangement of “o’s” and “1’s” store information in two dimensions in electronic devices. Due to its helical structure, DNA stores many times more information in three dimensions. Information cannot come about by random events, it must be put in. Bill Gates, the founder of Microsoft, said: DNA is like a computer program, but far, far more advanced than any software ever created. This is all powerful evidence for a Creator.
Every creature reproduced after its own kind (Genesis 1:21, 24 and twice in 25)
The DNA of a creature insures that the offspring is the same as the parents, because if a particular feature is not in the DNA of the parents it will not be expressed in their progeny. Rabbits produce rabbits and pumpkins produce pumpkins as the Bible says. This scientific fact shows Darwin’s idea of “acquired characteristics” to be wrong. Darwin explained giraffes as coming from a horse-like creature that over generations continually stretched its neck to reach higher leaves, which is utterly false.
So God created man in his own image, in the image of God he created him; male and female he created them. (Genesis 1:27)
Our gender is “hard wired” into our DNA. Males possess an X and a Y chromosome, whereas females have two X chromosomes. This is in every one of the 37 trillion cells that make us up. It does not matter if a person “identifies” as the other sex or has had sex reassignment surgery or hormones, a person’s sex is fixed and unchangeable as the Bible states. For example, if a few human hairs were found at a crime scene, a forensic scientist could determine if they were from a male or female by examining the chromosomes in them.
..but you must not eat from the tree on knowledge of good and evil, for when you eat of it you will surely die (Genesis 2:17)
Adam and Eve defied God’s clear instruction and when they did eat, mutations occurred in their DNA. DNA replicates itself as the cells that contain it divide. That is, the whole 6 billion nucleotides, and at an astonishing rate. If that replication is not a perfect copy of the original, it is called a mutation. Mutations started slowly with Adam and Eve, but they accumulate. Currently, we are amassing between 100 and 200 mutations every generation. The World Health Organisation estimates the number of genetic disorders caused by mutations to be over 10,000. These include, sickle cell anaemia, hemochromatosis, downs syndrome, cystic fibrosis and thousands of others. All cancers are a result of mutations and they will eventually bring an end to all life.
The initially slow accumulation of mutations very neatly explains the long-life spans of early people see; adefenceofthebible.com/2018/07/01/why-genetic-mutations-confirm-the-bible-and-oppose-evolution. The trajectory is downwards which is real and measurable. This is in totally contrast to what the evolution story of onwards and upwards.
Although Christians are constantly accused of believing in a God they cannot see, believing in fairy tales and needing a psychological crutch to get them through, the fact remains as this article has shown, if you are a Bible-believing Christian, then science is on your side. If you are an atheist, then science is your worst enemy.
