Comparing RNA and DNA

100

What is the sugar in RNA?

Ribose

200

Is RNA single or double stranded?

SINGLE

300

Does RNA contain uracil or thymine?

URACIL

400

What is the sugar in DNA?

Deoxyribose

Types of RNA

100

Along with up to 80 different proteins, these specific RNA molecules make up the subunits of a ribosome.

rRNA

200

These cellular structures, made of two subunits, serve as the exact location where protein synthesis occurs.

Ribosomes

300

This molecule acts as a copy of a DNA segment and serves as the direct blueprint for making a protein.

mRNA

400

These specific RNA molecules function as carriers that bring amino acids to the mRNA during protein synthesis.

tRNA

500

These chemical compounds are carried by tRNA molecules out of the cytoplasm to help build proteins.

Amino acids

RNA Synthesis

100

This is the name of the process where segments of DNA serve as templates to produce complementary mRNA molecules.

Transcription

200

These specific base sequences on DNA act as the exact regions where RNA polymerase binds to begin synthesis.

Promoters

300

This is the final step that new RNA molecules sometimes require before they are officially ready to be read.

RNA editing

400

Summary

During transcription, DNA segments act as templates to create complementary mRNA molecules. This process begins when RNA polymerase binds to specific DNA sequences called promoters. Once formed, these new RNA molecules sometimes require RNA editing before they can be read.
