biology rna and dna
| Term | Definition |
|---|---|
| transcription | the process where the DNA sequence in a gene is copied into mRNA |
| translation | mRNA leaves the nucleus to the cytoplasm where rRNA is to be decoded |
| DNA polymerase | enzyme that is needed for transcription |
| mRNA | code for making amino acid |
| tRNA | carries amino acids from the cytoplasm to the ribosomes |
| rRNA | forms polypetides which are the site of protein synthesis produced in the ribosomes in the cell |
| codon | 3 based sequence on mrna codes for amino acid |
| amino acid | building blocks for protein synthesis |
| what is the first step for protein syntheis | transcription |
| 2nd step | translation |
| what are the 2 main steps in protein synthesis | transcription and translation |
| what is the sugar in RNA | ribose |
| sugar for DNA | deoxyribose |
| DNA pairings | A-T G-C |
| RNA pairings | A-U G-C |
| 1st step in dna replication | it unzips dna helicase breaks down h- bond |
| where is the enzyme located | nucleus |
| where is the DNA polmerase located | nucleus |
| 2nd step in replication | uses the free floating nucleotides to build the new strands from the old strands |
| 3rd step | the ligase rechecks if everything is correct |
