The ENCODE Project, found that up to 98% of noncoding DNA is within 1000 base pairs of a protein-coding gene


The ENCODE project, which was a large-scale international research effort to map and characterize all of the functional elements in the human genome, did indeed find that 80% of noncoding DNA has some biochemical function.

The definition of "functional" used by the ENCODE project was broad, and included any DNA sequence that was associated with any kind of biochemical activity. This could include DNA sequences that are involved in the regulation of gene expression, the folding and packaging of DNA, or the repair of DNA damage.

It is important to note that not all of the functional noncoding DNA is equally important. Some of it may be involved in essential biological processes, while other parts may be more specialized or have a more limited role.

The ENCODE project has helped us to better understand the role of noncoding DNA in human biology, but there is still much that we do not know. As we continue to study the human genome, we are likely to learn more about the functions of noncoding DNA and its role in health and disease.

In addition to the ENCODE project, there have been other studies that have found that noncoding DNA plays a role in a variety of biological processes, including:

  • Gene regulation

  • DNA replication

  • DNA repair

  • RNA processing

  • Chromosome structure

  • Cell differentiation

  • Development

  • Aging

  • Disease

The functions of noncoding DNA are still being investigated, but it is clear that this type of DNA is essential for life and plays a vital role in many biological processes.

The ENCODE Project, found that up to 98% of noncoding DNA is within 1000 base pairs of a protein-coding gene. This means that noncoding DNA is often located in close proximity to genes, and it is thought to play a role in regulating gene expression.

For example, noncoding DNA can contain regulatory elements such as promoters and enhancers. Promoters are regions of DNA that RNA polymerase binds to in order to start transcription of a gene. Enhancers are regions of DNA that can activate or repress transcription of a gene, even if they are located far away from the gene itself.

Noncoding DNA can also contain other important elements, such as microRNAs. microRNAs are small RNA molecules that bind to mRNA and prevent it from being translated into protein. This can regulate the expression of genes by controlling how much protein is produced.

The study of noncoding DNA is a rapidly growing field, and scientists are still learning about its many functions. However, it is clear that noncoding DNA is not junk DNA, and it plays an essential role in regulating gene expression and maintaining genome stability.

The ATG sequence marks the beginning of a gene, and the TAA sequence marks the end of a gene. So, if a DNA sequence contains both an ATG and a TAA sequence within 1000 base pairs of each other, then it is considered to be close to a gene.

Francis Collins of the Human Genome Project ignored the 98% of the human DNA that was felt to be Junk DNA as per NeoDarwinism. He later admitted,

"In terms of junk DNA, we don’t use that term anymore because I think it was pretty much a case of hubris to imagine that we could dispense with any part of the genome, as if we knew enough to say it wasn’t functional. … Most of the genome that we used to think was there for spacer turns out to be doing stuff.”

Beyond the Sequence: The Epigenetic "Fingers" That Play the DNA Keyboard

Image
Imagine the keyboard itself is not a standard piano keyboard, but a modular synthesizer, capable of producing an almost infinite array of sounds. The DNA sequence, then, represents the fundamental building blocks of this synthesizer, the raw materials from which all sounds are generated. Epigenetics, our "fingers," manipulates these building blocks, adjusting parameters like volume, timbre, and rhythm, transforming the raw potential of the DNA sequence into a symphony of cellular functions. We can further refine the "fingers" analogy. Consider that each finger represents a distinct epigenetic mechanism: DNA methylation, histone modifications, and non-coding RNA.  DNA methylation, for instance, might be the "index finger," capable of precisely silencing specific genes, like muting individual keys on the synthesizer. Histone modifications, the "middle finger," could represent the ability to adjust the accessibility of the DN...

Why are Christian philosophers running towards Darwin while biologists are "running" away?

Image
As nature reveals the strength of epigenetics and the weakness of Neo-Darwinism, biologists are “running” away from the long-standing accepted theory. In The Federalist , April 2019, Benjamin Dierker reviews “Why one-third of biologists now question Darwinism”: "Current estimates are that approximately one-third of professional academic biologists who do not believe in intelligent design find Darwin’s Theory inadequate to describe all of the complexity in biology.” Dierker continues, “The important note is that these are not ideologues or religious zealots, nor do they propose a god or biblical solution.  Rather, they find problems in the lack of explanatory power of Darwin’s theory in light of modern understanding of mutation, variation, DNA sequencing and more. These expressions of doubt do not reject naturalism or evolution per se, but the rigor of the Neo-Darwinian model for explaining the development of life.” For 40 years, scientists calculated natural se...

Rewriting the Rules: Epigenomic Mutation Bias Challenges Randomness in Evolution

Image
This research challenges the long-held dogma that mutations occur randomly, irrespective of their consequences, by demonstrating a clear, epigenome-mediated mutation bias in Arabidopsis thaliana . The study meticulously unveils how mutation rates are not uniform across the genome but are significantly reduced in functionally constrained regions, particularly within gene bodies and essential genes. This discovery fundamentally alters our understanding of evolutionary processes, suggesting that mutation is not a purely directionless force. "Mutation bias reflects natural selection in Arabidopsis thaliana" This opening statement encapsulates the core finding: mutation rates are not random but reflect epigenetic pressures. The authors demonstrate that mutations are less frequent in crucial genomic regions, directly contradicting the prevailing theory of random mutation. This observation suggests an active mechanism that minimizes deleterious mutations in essentia...
