As a murder detective, I perceive the facility of alibis. When a possible suspect can show she or he wasn’t out there to commit a criminal offense as a result of they had been occupied elsewhere, they’re eradicated as a candidate for the homicide. Alibis create conundrums: situations troublesome to clarify primarily based on the impossibility of simultaneous appearances. In an identical means, the relationships between DNA, proteins, enzymes, and the cell’s membrane current a organic conundrum. Those that consider life can originate in our universe with out supernatural interplay (and steering) should overcome this conundrum in the event that they hope to account for the presence of life “contained in the room” of the pure universe by staying “contained in the room” for a proof. In my e-book, God’s Crime Scene: A Chilly-Case Detective Examines the Proof For A Divinely Created Universe, I describe the depth of the dilemma by illustrating the method of protein formation inside the cell.
Specifically fashioned purposeful proteins “unzip” a selected portion of the DNA by separating the helix on the center of its rungs. Extra specialised proteins then act as molecular machines, serving to to assemble nucleotide bases alongside one of many unzipped DNA segments.
This new assemblage of nucleotides is known as a messenger RNA (mRNA). As soon as fashioned, the shorter mRNA molecule detaches from the DNA and is carried off into the cell by further protein “helpers.” The mRNA is carrying directions wanted to construct a protein. It’s helped by one other RNA molecule generally known as switch RNA (tRNA). The mRNA and tRNA meet in a molecular machine known as a ribosome. This necessary mini-factory is constructed from proteins and RNA complexes. Right here, the tRNA transfers the message carried within the mRNA so amino acids can type every protein:

As soon as the sequence of amino acids has been established, one thing superb occurs. Relatively than stay in an extended chain, the amino acids start to roll up and fold onto each other, forming the precise completed form of the protein required to perform its job. This will likely take a number of seconds and scientists are nonetheless mystified as to how amino acids accomplish this job.
None of this may occur with out assistance from enzymes and the safety of the cell membrane. Enzymes are giant molecules constructed primarily with proteins. These necessary molecules activate and speed up the reactions associated to the whole lot from meals digestion to DNA formation. Almost each chemical response within the cell requires an enzyme to assist it occur quick sufficient for all times to outcome. Lastly, all of this exercise have to be protected. That’s the place the cell membrane turns into crucial. The membrane separates the inside of the cell from hostile exterior forces. It’s constructed with fatty molecules (lipids) and proteins (together with carbohydrates). Some cells even have an extra cell wall surrounding the membrane. Cell partitions are robust however versatile, and provide an extra layer of filtering and safety.
Now that we’ve reviewed the interior actions of the cell, you’ve in all probability already acknowledged the “hen and egg” drawback. Enzymes are vital for the well timed formation of proteins, however these enzymes are constructed, partially, with proteins. Worse but, this “hen and egg” drawback can also be current within the bigger relationships between the DNA, RNA, proteins, ribosomes and cell membrane.
Paul Davies describes the conundrum: “Take DNA… It has a grand agenda, however to implement this, DNA should enlist the assistance of proteins… proteins are made by sophisticated machines known as ribosomes, in accordance with coded instruction obtained from DNA by way of mRNA. The issue is, how might proteins get made with out the DNA code for them, the mRNA to transcribe the directions, and the ribosomes to assemble them? But when the proteins will not be already there, how can DNA, ribosomes and all the remainder of the paraphernalia get made within the first place? It’s Catch-22.”
Organic methods are replete with irreducibly complicated conundrums corresponding to these, and the very best rationalization for this type of complexity is clever interplay. Share on X
All these necessary machines, transportation autos and instruments should arrive on the mobile manufacturing facility concurrently and performance in unison if life is to be doable. The cell membrane and enzymes can’t be constructed with out proteins, however the protein formation have to be accelerated by enzymes and guarded by the membrane. Proteins can’t be fashioned with out DNA data and RNA exercise, however machines fashioned from proteins (like ribosomes), are a critically vital a part of this course of.
On this transient weblog submit (excerpted from God’s Crime Scene), I’ve solely described two of the numerous “hen and egg” issues naturalists should think about and clarify as they account for the origin of life within the universe. Organic methods are replete with irreducibly complicated conundrums corresponding to these, and the very best rationalization for this type of complexity is clever interplay. A supernatural designer can overcome the “hen and egg” conundrums we’ve described, and a Divine Designer of this nature stays the very best inference from the proof.
