DNA and RNA

yes they are, the black and red ones are not really swans.

Not now mitochondria in sperm!
OR
Dawkins was wrong. As were most others.

In "The Blind Watchmaker” (ref. 57, p. 176): “All the mitochondria in you are descended from the small population that traveled from your mother in her egg. Sperms are too small to contain mitochondria (our italics), so mitochondria travel exclusively down the female line, and male bodies are dead ends as far as mitochondrial reproduction is concerned. Incidentally, this means that we can use mitochondria to trace our ancestry strictly down the female line.”

A very minor effect, in the sense that the paternal mitochondrial contribution is minute. From the article:

In contrast, the mammalian oocyte contains around 100,000 (105) to 100,000,000 (108) mitochondria (16), and the human oocyte in particular is estimated to contain 100,000 (105) copies of mtDNA (17). Thus the oocyte’s mtDNA copy number exceeds that of the sperm by a factor of at least 1000 (103).

The police do not keep DNA profiles of suspects after they are cleared. But somehow enough DNA of a relative of the Idaho killer was in a public file.

Article is from 1996. There must certainly exist some more recent information.

Well now. They have been selling her cells and DNA for decades. The least they could do is clone her back from those cells. Minus the cancer gene.

Karikó's work includes the scientific research of RNA-mediated immune activation, resulting in the co-discovery with American immunologist Drew Weissman of the nucleoside modifications that suppress the immunogenicity of RNA

mRNA is produced by synthesising a ribonucleic acid (RNA) strand from nucleotide building blocks according to a deoxyribonucleic acid (DNA) template, a process that is called transcription.[2] When the building blocks provided to the RNA polymerase include non-standard nucleosides such as pseudouridine — instead of the standard adenosine, cytidine, guanosine, and uridine nucleosides — the resulting mRNA is described as nucleoside-modified.[3]

I'm now prevented from using the DVD classes of a particular courses outfit, so started to look for Covid videos on Youtube.
