RNA and Protein Synthesis

DNA and RNA are nucleic acids. True False DNA vs. RNA DNA double stranded deoxyribose sugar Thymine RNA single stranded ribose sugar Uracil What molecule is messenger RNA transcribed from? DNA rRNA tRNA none Drag the correct phrase to the type of RNA. mRNA complementary copy of DNA made in the nucleus rRNA makes up ribosomes tRNA carries amino acids to ribosomes and matches to mRNA What is the three base sequence on the mRNA that codes for a single amino acid? anticodons codons rRNA tRNA Where does transcription occur in the cell? ribosomes nucleus Golgi apparatus lysosome Match the following: DNA--> mRNA Transcription mRNA--> Protein Translation What is the process of DNA--> RNA--> Proteins called? Replication Mitosis Meiosis Protein Synthesis Dogma Exons are expressed as proteins. True False Transcribe the DNA strand: GAC ATG CAG into mRNA. CAG TAC GTC CTG TUC GUC CUG UAC GUC A short segment of an mRNA molecule is shown below. mRNA: AUG GUG CUG AAGTranslate this mRNA into proteins using the codon chart below. Met-Ala-Gly-Lys Met-Gly-Leu-STOP Met-Val-Leu-Lys Met-Val-Met-Lys What THREE events must happen to protect the mRNA molecule after transcription but before the mRNA can leave the nucleus to be translated? 5` cap splicing methylation poly A tail The 5` cap and the poly A tail are added to the mRNA to _ the molecule from nucleases splice protect destroy intertwine During splicing, sequences are removed from the mRNA molecule that do not code for a protein. What do we call the sequences that we KEEP because they are expressed as a protein? exons introns promoters tRNA The DNA sequences that tell RNA polymerase where to sit down and start transcription are called promoters exons 5` cap poly A tail
