DNA, RNA, and Protein Synthesis Review

Master DNA, RNA, and protein synthesis with our review worksheet! Perfect for biology students.

The primary function of DNA in cells is to serve as a storage form from unused nucleotides occupy space in the nucleus to keep the nucleus from collapsing store information that tells the cells which proteins to make serve as template for making long, spiral carbohydrates During DNA replication, the enzyme DNA polymerase separates the two nucleotide chains in a DNA molecule constructs new nucleotide chains that are complementary to the chains in the original DNA molecule breaks down the original DNA molecule into individual nucleotides joins two DNA molecules into a single molecule A section of one DNA strand has the sequence ACCGAGGTT. What is the sequence of a mRNA transcribed from this section of DNA? ACCGAGGUU ACCGAGGTT TGGCTCCAA UGGCUCCAA What process is shown in the diagram below? replication transcription translation protein synthesis According to the base pair rules, adenine binds with _ in RNA. Guanine Thymine Uracil Cytosine The two strands of a DNA molecule are held together by _ bonds. Hydrogen Strong Carbon Deoxyribose The mRNA codon of CCG codes for what amino acid? Leucine Proline Arginine Glycine The "backbone" or sides of DNA are made up of a 5 carbon sugar and _. Phosphate Deoxyribose Nitrogenous base Ribose What does "semi conservative replication" mean? Each new double helix contains two new strands Each new double helix contains one original (parent) strand and one new strand Each new double helix contains two original (parent) strands One new double helix contains two original (parent) strands and the other double helix contains two new strands. In a DNA double helix, a region along one strand of DNA has the following sequence:5'- GCCTATTC- 3'What is the complementary sequence? 3'- GCCTAATC- 5' 5'- CGGATTAG- 3' 5'- CGGAUUAG- 3' 3'- CGGATAAG- 5' Look at the following sequence in a nucleic acid: 5'- GCUA- 3' What kind of nucleic acid is this? DNA RNA Protein Amino acid If you are given a sequence of nucleotides, how can you determine whether it is DNA or RNA? If it has a T it is DNA If it has a U it is RNA All of the above Label the three parts of a DNA nucleotide on the image below. Phosphate Deoxyribose Sugar Nitrogenous Base
