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 |
