1. which type of rna delivers dnas \message\?
2. what are the 2 steps in protein synthesis? write them in order!
3. how many bases are there in one codon?
4. the central dogma of biology states that

Explanation:

1. mRNA (messenger RNA) is transcribed from DNA and carries its genetic information (the "message") to the ribosome for protein synthesis.
2. Transcription is the first step where DNA is copied into mRNA. Translation is the second step where mRNA is used to assemble amino acids into a protein.
3. A codon is a sequence of three nucleotides (bases) that codes for an amino acid.
4. The Central Dogma of Biology describes the flow of genetic information: DNA makes RNA (transcription), and RNA makes protein (translation).

Answer:

1. Messenger RNA (mRNA)
2. Transcription, then Translation
3. Three
4. DNA makes RNA makes protein (or DNA → RNA → protein)
