- Q1A section of a nucleic acid is shown below The process represented in the diagram produces a molecule that is complementary to the template strand of DNA. What type of molecule is produced?Messenger RNACarbohydratePolypeptideNew DNA60sBIOL.6c
- Q2If several pea plants with the genotype T TYy are crossed with pea plants with the genotype Ttyy, what percentage of the offspring will be expected to have the T TYy allele combination?50%40%25%75%60sBIOL.6f
- Q3A model of a DNA molecule is shown below. The arrow indicates -the bond between adjacent phosphate and deoxyribose moleculesthe hydrogen bond between complementary nucleotidesthe junction of introns and exons in the sense strand of DNAthe junction of a codon and a DNA triplet60sBIOL.6a
- Q4A codon chart is shown below. Which of these changes to the DNA triplet 3' GCT 5' will affect the protein produced?GCATCCGTTTCT60sBIOL.6e
- Q5Crossing-over between nonsister chromatids during meiosis is significant in heredity. This process most likely leads to an increase in which of the following?The occurrence of polyploidyGenetic variationThe expression of dominant traitsNumber of gametes60sBIOL.6g
- Q6Characteristics such as a widow's peak or attached earlobes are determined by the genetic code. Which components of DNA are referred to as the genetic code?Deoxyribose sugarsPhosphate groupsNitrogenous basesHydrogen bonds60sBIOL.6a
- Q7In cocker spaniels the allele for a black coat color (B) is dominant over the allele for a brown coat color (b). If a brown cocker spaniel is crossed with a heterozygous black cocker spaniel, which of the following genotypic ratios can be expected?2 BB: 0 Bb: 2 bb1 BB: 2 Bb: 1 bb2 BB: 1 Bb: 0 bb0 BB: 2 Bb: 2 bb60sBIOL.6f
- Q8How does DNA in cells determine an organism's complex traits?DNA folds into the nucleus of each of the cells of an organismDNA produces the energy an organism needs in order to growDNA contains codes for proteins, which are necessary for the growth and functioning of an organismDNA separates into long single strands that make up each part of an organism60sBIOL.6a
- Q9The fact that a strain of yeast with a certain defective gene can use the human version of the gene to repair itself is evidence that yeast and humans -both have eukaryotic cellsdepend on the same food supplyhave identical genomesshare a genetic code60sBIOL.6b
- Q10A mutation that occurs in the gametes of an organism will most likely be transferred to which of the following?The offspring of the organismThe siblings of the organismThe mating partner of the organismThe other organisms living nearby60sBIOL.6e
- Q11Early-onset Alzheimer's disease affects people under the age of 65. Less than five percent of people who are diagnosed with Alzheimer's disease have this type. Many cases of early-onset Alzheimer's disease are inherited, a type known as familial Alzheimer's disease (FAD). Which statement is best supported by this information?Natural selection will continue to reduce the incidence of FAD.FAD affects only the genes of middle-aged people.Deletion of one amino acid causes FAD.FAD is the result of a genetic change in one or more chromosomes.60sBIOL.6e
- Q12Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?FertilizationMitosisBinary fissionMeiosis60sBIOL.6g
- Q13The sequence of nitrogenous bases in DNA varies widely. The sequence of the bases in DNA is most important for which of the following?Preventing mutations from occurring during DNA replicationAllowing the DNA to have the shape necessary for replicationHelping form the sugar-phosphate backbone of DNA moleculesProviding the instructions for the traits of an organism60sBIOL.6a
- Q14Four different types of cells are shown below. Which characteristic is shared by all four cells?Genetic material composed of DNAA mechanism for transforming sunlight into energyMembrane-bound organelles that transport substancesSelf-locomotion60sBIOL.6b
- Q15In the 1860s Gregor Mendel performed numerous dihybrid crosses between pea plants. Dihybrid crosses involve the study of the inheritance patterns related to two different traits. In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BbFf x bbff cross would be expected to be heterozygous for both traits?50%0%100%25%60sBIOL.6f
