Answer the following question given this paragraph: 3.4 | Protein Synthesis By the end of this section, you will be able to: Explain how the genetic code stored within DNA determines the protein that will form Describe the process of transcription Describe the process of translation Discuss the function of ribosomes It was mentioned earlier that DNA provides a "blueprint" for the cell structure and physiology. This refers to the fact that DNA contains the information necessary for the cell to build one very important type of molecule: the protein. Most structural components of the cell are made up, at least in part, by proteins and virtually all the functions that a cell carries out are completed with the help of proteins. One of the most important classes of proteins is enzymes, which help speed up necessary biochemical reactions that take place inside the cell. Some of these critical biochemical reactions include building larger molecules from smaller components (such as occurs during DNA replication or synthesis of microtubules) and breaking down larger molecules into smaller components (such as when harvesting chemical energy from nutrient molecules). Whatever the cellular process may be, it is almost sure to involve proteins. Just as the cell's genome describes its full complement of DNA, a cell's proteome is its full complement of proteins. Protein synthesis begins with genes. A gene is a functional segment of DNA that provides the genetic information necessary to build a protein. Each particular gene provides the code necessary to construct a particular protein. Gene expression, which transforms the information coded in a gene to a final gene product, ultimately dictates the structure and function of a cell by determining which proteins are made. The interpretation of genes works in the following way. Recall that proteins are polymers, or chains, of many amino acid building blocks. The sequence of bases in a gene (that is, its sequence of A, T, C, G nucleotides) translates to an amino acid sequence. A triplet is a section of three DNA bases in a... Q: The sequence of bases in a gene translates to the sequence of what protein components? Choices: - protein acids - rna acids - molecular acids - amino acids A:
amino acids

This marimba uses gourds as resonance chambers to amplify its sound. (credit: APC Events, Flickr). Q: Resonance has been used in what kind of human-made recreational objects since prehistoric times? Choices: - toys - paintbrushes - arrows - musical instruments A:

Question: Answer the following question given this paragraph: Check Your Learning Ammonia can be liquefied by compression at room temperature; oxygen cannot be liquefied under these conditions. Why do the two gases exhibit different behavior? Answer: The critical temperature of ammonia is 405.5 K, which is higher than room temperature. The critical temperature of oxygen is below room temperature; thus oxygen cannot be liquefied at room temperature. Q: Unlike ammonia, oxygen cannot be liquefied at room temperature because its what is below room temperature? Choices: - relaxed temperature - leading temperature - particular temperature - critical temperature A:
Answer: critical temperature

Answer the following question given this paragraph: The somatic nervous system also controls some unconscious movements, called reflexes. A reflex is a very rapid motor response that is not directed by the brain. In a reflex, nerve impulses travel to and from the spinal cord in a reflex arc , like the one in Figure below . In this example, the person jerks his hand away from the flame without any conscious thought. It happens unconsciously because the nerve impulses bypass the brain. Q: What is the term for the unconscious movements controlled by the somatic nervous system? Choices: - senses - mechanisms - tremors - reflexes A:
**Answer**
reflexes

Answer the following question given this paragraph: Prokaryotic cells are cells that lack a nucleus. The DNA in prokaryotic cells is in the cytoplasm, rather than enclosed within a nuclear membrane. All the organisms in the Bacteria and Archaea Domains have prokaryotic cells. No other organisms have this type of cell. Organisms with prokaryotic cells are called prokaryotes . They are all single-celled organisms. They were the first type of organisms to evolve. They are still the most numerous organisms today. Q: What significant part of the cell do prokaryotic cells lack? Choices: - a cell wall - a ribosome - mitochondrial dna - a nucleus A:
**Answer**
a nucleus
