A new study in Nature challenges prevailing theories, suggesting that Homo sapiens evolved from multiple diverse populations across Africa, with the earliest detectable split occurring 120,000-135,000 years ago, after prolonged periods of genetic intermixing. There is broad agreement that Homo sapiens originated in Africa.

At least 75 per cent of our DNA really is useless junk after all

Each DNA sequence that contains instructions to make a protein is known as a gene. The size of a gene may vary greatly, ranging from about 1,000 bases to 1 million bases in humans. Genes only make up about 1 percent of the DNA sequence. DNA sequences outside this 1 percent are involved in regulating when, how and how much of a protein is made.

Like René Magritte's painting of a pipe entitled "Ceci n'est pas une pipe" — or "This is not a pipe" — what is called "the human genome" today in fact "doesn't exist," says Penn State Professor Ken Weiss at The Mermaid's Tale blog. The human genome is no more real than "the chair" or "the dog," he adds. Paraphrasing Plato, Weiss says that ...

In all cells, DNA does not exist free in solution but rather as a protein-coated complex called chromatin. In prokaryotes, the loose coat of proteins on the DNA helps to shield the negative charge of the phosphodiester backbone. Chromatin also contains proteins that control gene expression and determine the characteristic shapes of chromosomes ...

DNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.

Principles of Biochemistry/Nucleic acid I: DNA and its nucleotides

In living organisms, DNA does not usually exist as a single molecule, but instead as a pair of molecules that are held tightly together. These two long strands entwine like vines, in the shape of a double helix. The nucleotide repeats contain both the segment of the backbone of the molecule, which holds the chain together, and a base, which ...

It's the End of the Gene As We Know It - Nautilus

The startling implication is that the gene as popularly conceived—a blueprint on a strand of DNA, determining development and its variations—does not really exist. So it is, in a review in the journal Genetics in 2017, that the geneticists Petter Portin and Adam Wilkins question "the utility of the concept of a basic 'unit of ...

The configuration of the DNA molecule is highly stable, allowing it to act as a template for the replication of new DNA molecules, as well as for the production (transcription) of the related RNA (ribonucleic acid) molecule.A segment of DNA that codes for the cell's synthesis of a specific protein is called a gene.. DNA replicates by separating into two single strands, each of which serves ...

How, then, does DNA polymerase add the first nucleotide at a new replication fork? Alone, it can't! The problem is solved with the help of an enzyme called primase. Primase makes an RNA primer, or short stretch of nucleic acid complementary to the template, that provides a 3' end for DNA polymerase to work on. A typical primer is about five to ...

Codons. Cells decode mRNAs by reading their nucleotides in groups of three, called codons. Here are some features of codons: Most codons specify an amino acid. Three "stop" codons mark the end of a protein. One "start" codon, AUG, marks the beginning of a protein and also encodes the amino acid methionine.

Conclusion. DNA does not exist. They may be able to perform race based testing and disease prediction by examining our bacteria, but there is no such molecule as 'DNA' and all genetics science is one big hoax. 'DNA forensics' is yet another hoax. Something which has been implicitly acknowledged by the MSM.

DNA vs. RNA - 5 Key Differences and Comparison

DNA is a much longer polymer than RNA. A chromosome, for example, is a single, long DNA molecule, which would be several centimetres in length when unraveled. RNA molecules are variable in length, but much shorter than long DNA polymers. A large RNA molecule might only be a few thousand base pairs long. Sugar.
