Q: Answer the following question given this paragraph: RNA analysis is performed to study gene expression patterns in cells. RNA is naturally very unstable because RNAses are commonly present in nature and very difficult to inactivate. Similar to DNA, RNA extraction involves the use of various buffers and enzymes to inactivate macromolecules and preserve the RNA. Gel Electrophoresis Because nucleic acids are negatively charged ions at neutral or basic pH in an aqueous environment, they can be mobilized by an electric field. Gel electrophoresis is a technique used to separate molecules on the basis of size, using this charge. The nucleic acids can be separated as whole chromosomes or fragments. The nucleic acids are loaded into a slot near the negative electrode of a semisolid, porous gel matrix and pulled toward the positive electrode at the opposite end of the gel. Smaller molecules move through the pores in the gel faster than larger molecules; this difference in the rate of migration separates the fragments on the basis of size. There are molecular weight standard samples that can be run alongside the molecules to provide a size comparison. Nucleic acids in a gel matrix can be observed using various fluorescent or colored dyes. Distinct nucleic acid fragments appear as bands at specific distances from the top of the gel (the negative electrode end) on the basis of their size (Figure 17.4). A mixture of genomic DNA fragments of varying sizes appear as a long smear, whereas uncut genomic DNA is usually too large to run through the gel and forms a single large band at the top of the gel. Q: What type of analysis is performed to study gene expression patterns in cells? A:
Answer: rna analysis

Answer the following question given this paragraph: Crystalline solids are generally classified according the nature of the forces that hold its particles together. These forces are primarily responsible for the physical properties exhibited by the bulk solids. The following sections provide descriptions of the major types of crystalline solids: ionic, metallic, covalent network, and molecular. Q: What kind of solids are generally classified by the forces that hold their particles together and include ionic, metallic, covalent network, and molecular types? A:
OPTIONS:
- distinct solids
- helium solids
- flat solids
- crystalline solids
crystalline solids

Answer the following question given this paragraph: Many transition metals and their compounds are used as catalysts. Given MnO 2, FeCl3, Pt, and Ni, which would you select for each purpose and why?. Q: Many transition metals and their compounds are used as what? A:
OPTIONS:
- insulators
- bases
- sealants
- catalysts

Answer: catalysts

input with options: Answer the following question given this paragraph: All life relies on a relatively narrow range of pH, or acidity. That's because protein structure and function are very sensitive to pH. Air pollution can cause precipitation to become acidic. Nitrogen and sulfur oxides, mainly from motor vehicle exhaust and coal burning, create acids when they combine with water in the air. The acids lower the pH of precipitation, forming acid rain . If acid rain falls on the ground, it may damage soil and soil organisms. If it falls on plants, it may kill them (see Figure below ). If it falls into lakes, it lowers the pH of the water and kills aquatic organisms. Q: When the ph of precipitation is lowered because of air pollution, what results? A:
OPTIONS:
- abnormal rain
- climate change
- sleet
- acid rain
output:
acid rain
