For each of the following, identify the type of RNA involved (mRNA, rRNA, or tRNA). _____ a. Transports the correct amino acid to the ribosome, using the information encoded in the mRNA. _____ b. Is a major component of ribosomes. _____ c. Specifies the order of amino acids in a protein, using a series of three-base codons, where different amino acids are specified by particular codons. _____ d. Contains a three-base anticodon that pairs with a complementary codon revealed in the mRNA. _____ e. Assists in making the bonds that link amino acids together to make a protein.
What is the main function of tRNA in relation to protein synthesis? a. inhibits protein synthesis b. proofreading c. identifies amino acids and transports them to the ribosome d. all of these 2. Translation is the process where a. mRNA is created in the nucleus b. glucose molecules are made c. mRNA is decoded to form a protein d. is where lipids are synthesized 3. What is an anticodon? a. the part of an mRNA that signals translation termination b. the part of an mRNA that signals the start of translation c. the part of a tRNA that binds to a codon in mRNA d. the part of a tRNA that accepts an amino acid, via a reaction catalyzed by tRNA synthetase 4. Alternative splicing refers to a. the use of introns as exons, or vice versa, during RNA processing b. splicing out of damaged DNA by DNA repair enzymes c. joining of RNA from two different genes to form a new mRNA d. the use of alternative reading frames when translating an mRNA
