Protein Synthesis Worksheet

Master protein synthesis! Worksheet covers transcription, translation, DNA/RNA, codons, and ribosomes.

Enter your full name and class period below: 1) A is a(n) anticodon.2) B is a tRNA molecule.3) C is a mRNA molecule.4) D is the ribosome.5)E is a(n) amino acids. Where does of the first step of protein synthesis occur? Nucleus Ribosome Mitochondria Cytoplasm Where does the second step of protein synthesis occur? Nucleus Ribosomes Mitochondria Smooth ER Fill in the blanks. a) The first step of protein synthesis is transcriptionb) The second step of protein synthesis is translationc) The 3 bases on the mRNA strand are called codonsd) The 3 bases on the tRNA are called anticodon Nitrogen bases are read _ bases at a time. 1 2 3 6 RNA vs DNA DNA Deoxyribose sugar Double stranded Thymine Anti-parallel Only in nucleus RNA Single stranded Ribose sugar Uracil Creates the ribosome 3 different types Can leave the nucleus Transcription vs Translation Transcription DNA to mRNA Only in the nucleus Translation mRNA to amino acids On the ribosomes Creates polypetide bonds tRNA molecules bring amino acids to the ribosome Put in correct order Six Step: A stop codon is reached, the newly formed protein is released.First Step: DNA strands unwind and separateThird Step: mRNA leaves the nucleus and attaches to a ribosomeFourth Step: tRNA binds to the corresponding mRNASecond Step: mRNA copies DNA according to complementary base pairing.Fifth Step: amino acids bind to each other, the chain lengthens. 1) A is a(n) amino acid.2) B is a ribosome.3) C is mRNA.4)D is DNA. What is the amino acid that goes with the mRNA:AAG? PRO LYS GLY SER What is the amino acid that goes with the mRNA:UCG? TRP SER CYS ARG What amino acid goes with the DNA: CCA? PRO ALA GLY VAL If the mRNA strand is AUG – CAU—AUU—UGA –CCC. The amino acid sequence is.....

A base A gene A codon An anticodon
