The single-cell organism that does not contain a well-defined nucleus and membrane are called prokaryotes. The genetic information is contained in the nucleoid of the cell.
<h3>What is a nucleoid?</h3>
Nucleoid is a region in the cytoplasm of the prokaryotic cell that is an irregular-shaped structure that consists of the genetic material of the cell.
The process of the replication and transcription of the DNA and RNA of the prokaryotic cell occurs here and is different from the eukaryotic nucleus by lacking a nuclear membrane.
Therefore, prokaryotic genetic material is contained in the option D. nucleoid of the cell.

Here's it! Good Luck!
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano, and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.
Hope this helps!
The source code of transcription is mRNA.
