BIOL 101 Quiz Cells to Organisms Liberty Lynchburg/BIOL 101 Quiz Cells to Organisms Liberty Lynchburg Question 1 3.2 / 3.2 pts Which of the following is not a recognized organ system within the human body? the integumentary system the ovarian follicle system the circulatory system the muscular system the skeletal system Question 2 3.2 / 3.2 pts Which of the following sequences best represents the overall flow of information in a cell? replication, division, protein processing, protein import transcription, pre-mRNA processing, translation, protein processing, export glucose import, glycolysis, Kreb’s cycle, electron transfer replication, translation, protein import, membrane assembly ADP synthesis, ATP synthesis, biosynthesis, protein assembly Question 3 3.2 / 3.2 pts Animal development and automobile development differ in that the initial components are simpler than the final product. automobile development requires introduction of material from the outside. animal development requires the input of energy. information for developing an animal comes from within the animal. automobile development can suffer from informational errors. Question 4 3.2 / 3.2 pts The term “transcription” means the process of converting newly translated proteins into processed proteins. reading a base sequence in DNA to generate a complementary base sequence in RNA (mRNA). converting the information in amino acids back into DNA. copying the information in ADP into ATP. converting the amino acids in RNA into amino acids in proteins. Question 5 3.2 / 3.2 pts The “S” phase of the cell cycle represents the activity of RNA message generation. DNA synthesis. protein synthesis. nuclear separation. chromosome separation. Question 6 3.2 / 3.2 pts A sequence of human cell divisions accompanied by some growth and cell differentiation convert an early ___________ into a hollow ball of cells called a _________. zygote, morula primitive streak, neural tube morula, blastocyst blastocyst, chorion zygote, 8-cell stage embryo IncorrectQuestion 7 0 / 3.2 pts The de-condensation of visible chromosomes back into chromatin fibers is a defining feature of which phase of the cell cycle? prophase S phase G1 phase metaphase telophase Question 8 3.2 / 3.2 pts A three-dimensional, folded molecule shaped like an “L” with an anticodon at one end and an amino acid attachment site at the other end: an rRNA RNA polymerase a tRNA an mRNA poly-A tail a small ribosomal subunit Question 9 3.2 / 3.2 pts Which of the following is not a role of the ribosome or its subunits? creating a channel for mRNA to enter and exit helping tRNA anti-codons to bind to mRNA codons comparing tRNA anti-codons against corresponding mRNA codons binding amino acids together to form a polypeptide chain generating ATP energy to be used by the cell in biosynthesis Question 10 3.2 / 3.2 pts There are more than four kinds of amino acids in proteins. Each kind of amino acid must be coded for in mRNA. Thus, a short sequence of mRNA bases called a(n) _________ is used to code for each amino acid in the translation process. . . . . . . . . .
