An experiment is performed in which the sequence of bases coding for the signal peptide is deleted from an mRNA molecule which codes for a lysosomal enzyme. When this mRNA is expressed in a cell, the resulting protein would be expected to be found in the: correct answers Cytoplasm Which of th following is not a typical component of biological membranes in eukaryotic cells? a. proteins that span the lipid bilayer b. fatty acids linked to glycerol by ester bonds c. triglycerides d. phospholipids correct answers c. triglycerides Proteolytic enzymes that function best at low pH are: correct answers lysosomal proteins and enzymes synthesized on rough endoplasmic reticulum. Which of the following would you expect to find in both prokaryotes and eukaryotes? a. endoplasmic reticulum b. lysosomes c. ribosomes d. mitochondria e. Golgi apparatus correct answers c. ribosomes Hydrogen bonding correct answers 1. binds purines and pyrimidines to one another to hold the two strands of the DNA together 2. determines the secondary structure of proteins 3. keeps water liquid at room temperature at sea level 4. permits bases in RNA to bind to bases in DNA during transcription Myosin and kinesin (which are cytoplasmic proteins) both: correct answers Are ATPases and undergo a structural change after converting ATP to ADP and inorganic phosphate. During translation, covalent bonds are formed between adjacent _____ by _____. correct answers amino acids, ribosomal RNA The 3D shape (tertiary structure) of a protein results largely from the interaction of the _____ with one another or with water. correct answers R-groups The Signal Recognition Particle (SRP) plays an important role in the synthesis of some proteins, and is composed of proteins and a small molecule of RNA. You can conclude that the nucleic acid component of this protein: correct answers was synthesized in the nucleus from a DNA template. In 1483, Richard III had his two nephews, ages 9 an 12, arrested and confined to the tower of London. They were never seen alive again outside the tower, and were presumed murdered. In 1674, two small skeletons were found in a closet beneath a stairway and assumed to be the
