Protein Synthesis Practice

Master protein synthesis! Practice DNA transcription, mRNA translation, and amino acid sequencing.

Comparing DNA and RNA Read each description, then place it under the correct molecule DNA A, G, C, T contains deoxyribose sugar found in nucleus of eukaryotic cells Deoxyribonucleic acid double strand RNA A, G, C, U contains ribose sugar found in nucleus and cytoplasm Ribonucleic Acid single strand DNA Transcription: You will transcribe the DNA sequence, then translate the mRNA codons into amino acids. Use all capital letters for RNA. Use capital and lower case letters for amino acids. Below is the DNA strand TAC - CGT - ATA - CAG - CTA - ATTCreate the mRNA AUG- GCA- UAU - GUC - GAU- UAAAmino acids Met - Ala - Tyr - Val - Asp - Stop Types of RNA Correctly match the picture and definition for each type of RNA. RNA Definition Picture mRNA Carries the copy of DNA's code from the nucleus to the ribosomes tRNA transfers correct amino acids to ribosomes rRNA Makes the ribosome, where amino acids are linked together to make proteins Complete mRNA using the DNA strand.Complete amino acids using CODON wheel. DNA: TAC GCC CCA AGT AGC ATCmRNA: AUG-CGG-GGU-UCA-UCG-UAGAA: Met-Arg-Gly-Ser-Ser-STOP What are the monomers of proteins called? amino acids fatty acids nucleotides monosaccharides When amino acids are linked together, a molecule is created called a _ chain. These chains make up proteins. polysaccharide triglyceride polypeptide nitrogenous bases What are stop CODONS? They tell the ribosome when to stop making proteins They tell the mRNA when to stop leaving the nucleus They tell the ribosomes to keep making proteins Amino Acids Match the amino acid to the correct code. Use your CODON wheel or chart for help. AUG Met AAA Lys CCC Pro Which type of RNA starts in the cell's nucleus during transcription, then carries the DNA code outside of the nucleus.? rRNA tRNA mRNA DNA Which of the following processes occurs in the ribosomes, and decodes the mRNA into amino acids? replication transcription translation respiration Which of the following peptide chains is created by the following mRNA code?AUG CCA CGA GCU UAU Met-Lys-Pro-Gly-Phe Met-Pro-Arg-Ala-Tyr Met-Lys-Phe-Asp-Sir What are the four DNA nitrogenous bases? Select the correct four answers from the list. cytosine guanine thymine uracil adenine amino acids transport Where does transcription occur in the cell? nucleus cytoplasm ribosome golgi body Where in the cell does translation happen? nucleus mitochondria chloroplasts ribosomes What type of RNA makes up ribosomes? mRNA rRNA tRNA zRNA Which explanation below BEST describes how DNA and RNA share information for protein synthesis? DNA wraps around a strand of RNA transferring nucleotides for protein synthesis. DNA leaves the nucleus for a ribosome where mRNA will perform protein synthesis. DNA unzips, RNA is created and transcribes the genetic information from DNA for protein synthesis. RNA will unzip and DNA will transcribe the genetic information from the DNA in the ribosome. Which explanation BEST describes how the genetic instructions carried by the mRNA are translated, or decoded, to make a protein? The rRNA bases are read at the ribosome. The tRNA brings peptide acid to the ribosome. The peptide acids bind together to make a protein chain. In the nucleus, the mRNA bases are read. The mRNA brings the amino acid to the ribosomes. The amino acids bind to create a protein. In the nucleus, the tRNA is read, then the mRNA brings the amino acid to the nucleus. The amino acids bind to create a protein. The mRNA bases are read at the ribosome, then the tRNA brings amino acids to the ribosome. The amino acids bind together to make a protein. Use the picture of protein synthesis to answer the question.Find 1. in the picture. What is the name of the object the arrow pointing to? anticodon codon nucleotide phosphate group
