Question | Answer |
what is the shape of DNA? | a double helix |
what are the sides and backbones of DNA made of? | nucleotides (sugars) |
what are the 4 nitrogen bases? | A-T, G-C |
what is the shape of RNA? | 1 single strand |
what are the nitrogen bases involved in RNA? | A-T, G-C |
what is the sugar involved in RNA? | ribose |
where is RNA located? | in the ribosomes |
how many stands are in DNA? | 2 strands |
what is the sugar involved in DNA? | deoxyribo |
DNA base pairing? | A-T, C-G |
RNA base pairing? | A-U, G-C |
what are the steps to DNA replication? | DNA unwinds, replication fork forms,DNA polymerse attaches to a new base. |
what is the role of DNA polymerase? | make DNA from nucleotides |
what is made in DNA replication? | new DNA for new cells |
what is the order of protein synthesis? | DNA -(transcription)-RNA-(translation)- protein |
what are the steps to transcription? | DNA unwinds, 1 strand is used as a template, RNA polymerse attaches to new base, mRNA goes to the ribosomes |
what is does transcription make? | a protein |
what are the steps to translation? | mRNA from transcription starts codon, RNA attches to mRNA,tRNA brings amino acids to anti codon, moves along |
what is made in translation? | protiens |
who are the founders of the structure of DNA? | Crick and Watson |
what is the purpose of mRNA? | sends messages to make a protein |
what is the purpose of tRNA? | transfers the amino acids |
what is the purpose of rRNA? | links amino acids to protiens |
what is a codon? | a sequence that make amino acids |
how many bases are in a codon? | 3 |
