Concept explainers
For each statement, identify which major theme is evident (the relationship of structure to function, information flow, pathways that transform energy and matter, interactions within biological systems, or evolution) and explain how the statement relates to the theme. If necessary, review the theme descriptions (see Chapter 1) and review the examples highlighted in blue in this chapter.

Genetics: From Genes to Genomes
- 1) The nucleolus is a cytoplasmic organelle involved in the synthesis of ribosomes (true or false ) 2)DNA is often referred to as supercoiled because it is most commonly found in cells as two strands of inter-wounded DNA (true or false ) 3) translation is a process of synthesizing proteins based on base sequences of mRNA molecule (true or false )arrow_forwardA student develops four models for the composition of a eukaryotic cell. The weight of the cell is broken down as the percentage of the total cell weight for each of the components. Which model indicates the CORRECT percentage values for the components of an actual cell and why? A Model A because this model shows that nucleic acids are the most abundant macromolecule, and nucleic acids are the most important macromolecule because they contain genetic information. B Model B because this model shows that proteins are the most abundant macromolecule, and proteins are the most important macromolecule because they are the most diverse and are involved in many cell structures and functions. C Model C because this model shows that phospholipids are the most abundant macromolecule, and phospholipids are the most important macromolecule because they are the main component of the cell membrane. D Model D because this model shows that nucleic acids are the least abundant…arrow_forwardRibosome, mitochondria, and golgi bodies are structures in cell whose forms dictate their physical functions. Describe their function in relation to their structure.arrow_forward
- Which of the following is FALSE regarding the four structures that BOTH prokaryotic and eukaryotic cells have in common and why are these essential structures for all cells?1 DNA directs protein production2 Mitochondria the power house of the cell3 Cytoplasm, aqueous interior of all cell houses organelles and other structure 4 cell membrane : regulates movement of molecules between cell and its surroundings5 ribosome build proteins according to the DNA's instructionsarrow_forwardMatch the following: Forms part of the subunits for the protein synthesizing organelle A molecule that binds to a specific codon and specific amino acid simultaneously Attaches the correct amino acid to its transfer RNA Provides the energy needed for synthesis reactions Produced in the nucleus, this molecule specifies the exact sequence of amino acids of the protein to be made May be attached to the ER or scattered in the cytoplasm [Choose ] [Choose ] [Choose ] [Choose ] [Choose ] [Choose ] SEXINVarrow_forwardGlycophorins are a type of membrane protein found on red blood cells. They allow red blood cells to circulate through the blood vessels without sticking to the walls of the blood vessels or to other cells. Describe how a glycophorin protein would be synthesized by the cell. Include What parts of the cell are involved and what happens at each location. The process of protein synthesis (i.e. transcription, translation, etc).arrow_forward
- Put the following steps of protein synthesis in order: STEP A - Anticodon attaches to the mRNA STEP B - mRNA leave the nucleus and attaches to a ribosome STEP C - complementary mRNA attaches to DNA STEP D - the amino acids bond, forming a protein C, B, A, D O A, C, B, D O D, C, A, B O B, C, A, Darrow_forwardWhy are proteins important for cells? A - They are the main source for energy inside cells. B - They control all cell structure and function. C - They only break down materials in the lysosome. D - They only create new ribosomes.arrow_forwardWhich statements correctly describe the rough endoplasmic reticulum (rough ER)? It has ribosomes bound to its membrane. It synthesizes proteins that will be sent out of the cell. It stores and releases calcium ions. It is connected to the membrane of the nucleus. It is used to transport mRNA to the cell membrane.arrow_forward
- (AKS 4a / DOK 1) Students in biology class were presented with the model below and asked to revise (change) the model to show which structures (letters) would be present after it is used for a cellular function such as muscle contraction, active transport, or mitosis.
