|---|---|
| made up of repeating subunits of nucleotides/ 2 chains of nucleotides | DNA |
| 3 parts of dna nucleotide | deoxyribose, phosphate, and nitrogen containing bases |
| 4 nitrogen bases | adenine, guanine, cytosine, thymine |
| 2 purines | adenine, guanine |
| suggested model double helix structure of DNA, 1953 | Watson and crick |
| Watson and crick Nobel prize in medicine award year | 1962 |
| 4 letters used to signify the nitrogen bases | A, G, C, T |
| process of copying DNA | replication |
| dna polymerase are... | enzymes |
| ATTCCG | original sequence of DNA |
| TAAGGC | New nucleotide chain in replication of DNA |
| one error for every .... paired nucleotides | 10k |
| proofreading (enzymes repairing errors) brings the error rate to one error every ... nucleotides | 1B |
| ... responsible for the movement of the genetic info from DNA in mucleus to the site of protein synthesis in cytosol | RNA |
| 2 pyrimidines | cytosine, thymine |
| 3 types of rna | messenger, transfer, ribosomal |
| what type of rna carries genetic info of the dna to cytosol | messenger |
| what type of rna binds to specific amino acids | transfer |
| what type of rna is the most abundant form | ribosomal |
| process by which genetic info is copied from DNA to RNA | transcription |
| whats the products of transcriptions | transcripts |
| 3 types of transcripts | mRNA, tRNA, rRNA |
| production of protein is | protein synthesis |
| proteins are... | polymers |
| a correlation between a nucleotide sequence and an amino acid sequence is | genetic code |
| 3 mRNA equals | codon |
| start codon | AUG |
| stop codon | UAA, UAG, UGA |
| process of assembling polypeptides from info encoded in mRNA is | translation |
| ribosomes are composed of ,,, | rRNA and proteins |
| ribosomes have ... that are key to translation | 3 binding sites |
