olya-2409 [2.1K]

Answer: DNA and RNA are both examples of nucleic acids

They consist of a strand of nucleotides with a phosphate group, a 5′ sugar and a nitrogenous base.

Extra info: DNA and RNA molecules are polymers. DNA is double stranded, whereas RNA is single stranded.

The nucleotides of DNA can pair together by base pairing, creating a strand that is complementary to its pair

Various types of RNA exist which have roles in protein synthesis as well as regulation of cellular programmes by fine-tuning gene expression.

Mrrafil [7]

Answer:

Examples of astronomical objects include planetary systems, star clusters, nebulae, and galaxies, while asteroids, moons, planets, and stars are astronomical bodies. The birth of the sun is what created the universe. When the sun was first born it had huge amounts of gravity. This gravity was strong enough to make rocks and other celestial bodies come together to form our planets.
