| Rna | uses information in DNA to synthesize proteins |
| RNA differs from dna in three ways: | 1.only 1 strand instead of 2 2. ribose instead of carbon sugar 3. uracil instead of thymine |
| Messenger RNA | transmits information from DNA- template for amino acids |
| Transfer RNA | bonds to only one specific type of amino acids |
| Ribosomal RNA | makes up ribosomes- most abundant form |
| transcription | genetic information is copied to DNA and RNA |
| step 1:enzyme | RNA polymerase binds to specific regions of DNA |
| promotors | marks the beginning of the DNA chain to be transcribed |
| eukaryotes | marks the beginning of a single gene |
| step 2: | polymerase attaches to the first DNA nucleotide on template |
| step 3: | begins adding complementary RNA nucleotides C to G and A to U |
| step 4: | when RNA polymerase reaches the sequence of nucleotides- termination signal- enzyme triggers a release of DNA |
| termination signal | marks the end of a gene in eukaryotes |
| genetic code on DNA is transcribed to RNA and is carried into the what | cytosol- protein synthesis |
