What does DNA do?

The blueprint for genetic makeup

What makes up a strand of DNA?

DNA strands are long chains of nucleotides, each composed of a phosphate group, a sugar molecule (deoxyribose), and one of four nitrogenous bases

What does RNA do?

RNA translates genetic information from DNA into proteins.

What makes up a strand of RNA?

RNA strands are long chains of nucleotides, each with a phosphate, a ribose sugar, and one of four bases: Adenine, Uracil, Guanine, or Cytosine.

What does transcription do?

Transcription converts genetic information from DNA into an RNA molecule.

What does translation do?

to convert the genetic information encoded in messenger RNA (mRNA) into functional proteins

How translation happen?
a. What is a codon?

Translation is the process where the ribosome reads mRNA codons (three-base sequences) and uses them to assemble a chain of amino acids into a protein.
