Biology 13.1-13.2
Term | Definition |
---|---|
RNA | Is a nucleic acid that directs the production of proteins |
Transcription | The process of changing DNA into RNA |
Codon | Is the three base "word" of mRNA used to determine the amino acid |
Transfer RNA | job is to carry an amino acid to the ribosome and find the correct codon. |
Translation | Determining the amino acid sequence that corresponds to the codon |
Anti-codon | Found on the tRNA molecule and has the complementary bases to an mRNA codon |
Exons | Are spliced back together to form the mRNA molecule |
polypeptide | A protein is made of a ________________chain of amino acids |
Messenger RNA | job is to carry encoded information to the ribosome. |
Intron | The segment of the DNA that is cut out prior to becoming mRNA |
Ribosomal RNA | Forms an important part of the subunits of the ribosome |
Differences of DNA and RNA: Uracil | RNA contains ______________ instead of Thymine |
Differences of DNA and RNA: Ribose | RNA contains _______________ instead of Deoxyribose |
Differences of DNA and RNA: Single Stranded | RNA is generally __________________ instead of double standed |
Why is RNA important? | RNA are involved in making proteins and RNA controls the assembly of amino acids into proteins |
Cytoplasm | This is where Protein synthesis takes place |
When transcribing from DNA to mRNA what is the opposite of (A) Adenine? | (U) Uracil |
What is the mRNA strand from this DNA strand? DNA: CAC TGT | GUG ACA |
What is the mRNA strand from this DNA strand? DNA: ACA GTG | UGU CAC |
