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 the following is a not a typical component of biological membranes in eukaryotic cells? correct answers triglycerides During translation, covalent bonds are formed between adjacent _______________ by ___________________ correct answers amino acids, ribosomal RNA Proteolytic enzymes that function best at low pH are: correct answers - lysosomal proteins - synthesized on rough endoplasmic reticulum Which of the following would you expect to find in both prokaryotes and eukaryotes? correct answers ribosomes In the _______, portions of the mRNA transcript are cut out and removed. The remaining regions of the mRNA called __________________ are ligated back together and translated in the ______ correct answers nucleus, exons, cytoplasm Hydrogen bonding correct answers - binds purines and pyrimidines to one another to hold the two strands of the DNA together - determines the secondary structure of proteins - keeps water liquid at room temperature - permits bases in RNA to bind to bases in DNA during transcription The three-dimensional 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 and 12 arrested and confined to the tower of London. They were never again seen alive 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 remains of the two boys. Which of the following would be consistent with the skeletons belonging to the Richard's nephews? correct answers The growth plates had not closed so that the diaphysis and epiphyses of the long bones were separate structures
