Unformatted text preview: Question 1 0 points Save The diagram below shows the inheritance of a sex-linked recessive trait. In generation II, female number 5 marries a man and has three children. One daughter and one son do not have the recessive trait; the other son does have the recessive trait. Based on this information, one can conclude that: the mother is homozygous for the trait. the father is homozygous for the trait. the father is heterozygous for the trait. the mother is heterozygous for the trait. Question 2 0 points Save The portion of the tRNA molecule that base-pairs with the mRNA is called the _______. complement codon reverse-complement anti-codon Question 3 0 points Save Prokaryotic cells do not need telomeres because: They have circular genomes instead of linear genomes. They have linear genomes instead of circular genomes. They replicate their DNA semi-conservatively, not conservatively. They replicate their DNA conservatively, not semi- conservatively. Question 4 0 points Save DNA damage is monitored by which tumor suppressor protein? p53 Rb (retinoblastoma) Guardase p21 Question 5 0 points Save Two different groups of imaginary grindylows live in geographically separated locations and rarely interbreed. On one occasion, a big-footed white grindylow does mate with a small-footed brown grindylow. Three offspring result: one big-footed brown grindylow and two small-footed brown grindylows. Which statement about the inheritance of color in grindylows is most likely to be correct? White is dominant to brown. Brown is dominant to white. White and brown are codominant. This cannot be answered without more information. Question 6 0 points Save Which of the following nucleic acids are not used during translation? tRNA mRNA DNA rRNA Question 7 0 points Save You have isolated the following sequence from the middle of a coding region of an mRNA of a protein: 5- AACGAAUUGAUCUAGGCACUGA-3 What is the likely reading frame of the protein? 5-AAC/GAA/...-3 5-ACG/AAU/...-3 5-CGA/AUU/...-3 It is impossible to determine. Question 8 0 points Save Nucleosomes: consist entirely of DNA. consist of DNA wound around a histone core. are present only during mitosis. are made of chromosomes. Question 9 0 points Save Translation of all proteins starts with which amino acid? methionine leucine alanine adenosine Question 10 0 points Save From lowest to highest in abundance, what is the correct order of the following eukaryotic chromosomal structures? centromere telomere origin of replication centromere origin of replication - telomere origin of replication centomere telomere telomere centromere origin of replication Question 11 0 points Save The microtubules of the mitotic spindle attach to a specialized structure in the centromere region of each chromosome called the: kinetochore...
