DNA and RNA serve what purpose within a cell and living things.

Biology
1 answer:
Lorico [155]3 years ago
4 0

Answer:

D. DNA Contains the genetic code / instructions for the cell and the living organism they build

Explanation:

DNA and RNA are nucleic acids that contain the genetic information so that a cell knows exactly what proteins it should make, what function it should serve.

Why not A: DNA and RNA don't strictly build cellular proteins; that job is up more to the ribosome, tRNA, and mRNA. While this could be acceptable, it's not as good an answer as D.

Why not B: This is incorrect.

Why not C: DNA and RNA don't do any of the dirty work of fighting off intruders; that's the job of the immune system, building antibodies, eating the viruses with white blood cells, and using the epidermis as a barrier to keep harmful things out.

The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

<h3>What is the indirect evidence that helped us determine the layers?</h3>

Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.

The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.

So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

Answer:

The pairing of the nitrogen bases in a DNA molecule is AT and CG. Let's say that the DNA strand has the sequence of ATCG. The complementary strand of that DNA strand will be TAGC. A and T & C and G must pair with each other. The replicated strand will be the same as the original strand because the complementary strand of the replicated strand will be ATCG, which is the same as the original strand.
