operons consist of: - Answer promoter, operator, coordinately related cluster of genes whose products function in a common pathway are human genes organized in operons? - Answer no responses caused by epinephrine binding to receptor - Answer --response may be relaxation of muscles through a G-protein pathway --other triggers contraction of muscles by opening calcium ion channels insulin receptor is what type of receptor? - Answer tyrosine kinase where is tRNA made? - Ans...

Why study cellular and molecular biology? - ANSWER-The connecting basis of all life is at the cellular and molecular level. DNA, RNA, proteins and the cellular mechanisms behind each of these form the fundamental basis of life. Many biological phenomena are better understood at the biochemical and molecular level. What are the 8 emergent properties of life? - ANSWER-Reproduction Growth and Development Order and Structure Metabolism Respiration Response to environmental stimuli Adaptatio...

What happens during G1? - Answer First growth phase; cell synthesizes proteins and produces cytoplasmic organelles What happens during the S phase? - Answer Synthesis; continues to grow as it copies chromosomes What happens during G2? - Answer Second growth phase; cell completes preparation needed to divide and continues basic life of the cell What happens during mitosis? - Answer Subdivided into prophase, metaphase, anaphase, and telophase; nuclear division What happens ...

BIO 311C QUESTIONS AND ANSWERS A+ GRADED ring structures contain what? hydroxyl group what are glycosidic linkages? covalent bonds formed between the two monosaccharides what are oligosaccharides used for? communication what are polysaccharides? sugar polymers (macromolecules) how is structure of polysaccharides determined? type of monomers/locations of bonds glycogen, starch, and cellulose all built from glycogen? true glycogen, starch, and cellulose can all provide energy for...

BIO 311C FINAL EXAM QUESTIONS AND ANSWERS A+ GRADED Define monomers, polymers and macromolecules What reactions happen in condensation synthesis and hydrolysis? 1) condensation synthesis: MAKES polymers by releasing water molecules, condensation synthesis is important in anabolic processes (builds complex from simple) 2) hydrolysis BREAKS DOWN polymers into monomers by adding -H to one molecule and -OH to another (uses n-1 water molecules) while hydrolysis is important in catabolic proc...

BIO 311C QUESTIONS AND ANSWERS A+ GRADED What are the two laws of inheritance? 1. Law of Segregation- Allele pairs segregate during gamete formation and the paired condition is restored by the random fusion of gametes at fertilization. Example: **Monohybrid Cross-(pPxpp) 3:1 ratio after crossing pure bred pea varieties with either spherical seeds or dented seeds. Found that 3/4th of the F2 progenies had spherical seeds and 1/4th had dented seeds. 2. Law of independent assortment- the ...
