One example of codominance is fur color in cattle; the alleles for red fur and white fur are codominant. If a homozygous red cow and a homozygous white bull mate, what would you expect to find in their offspring?.912.l.16.2> They will all have white fur. Their fur will be a mixture of red and white hairs. Their fur will be a lighter shade of red. They will all have red fur. Question 10 If a tRNA molecule has an anticodon which reads AUG, what will it match up with and what amino acid is it carrying? .912.l.16.5> U C A G UUU Phenylalanine UCU Serine UAU Tyrosine UGU Cysteine U U UUC Phenylalanine UCC Serine UAC Tyrosine UGC Cysteine C UUA Leucine UCA Serine UAA Stop UGA Stop A UUG Leucine UCG Serine UAG Stop UGG Tryptophan G CUU Leucine CCU Proline CAU Hisitidine CGU Arginine U C CUC Leucine CCC Proline CAC Hisitidine CGC Arginine C CUA Leucine CCA Proline CAA Glutamine CGA Arginine A CUG Leucine CCG Proline CAG Glutamine CGG Arginine G AUU Isoleucine ACU Threonine AAU Asparagine AGU Serine U A AUC Isoleucine ACC Threonine AAC Asparagine AGC Serine C AUA Isoleucine ACA Threonine AAA Lysine AGA Arginine A AUG Methionine/Start ACG Threonine AAG Lysine AGG Arginine G GUU Valine GCU Alanine GAU Aspartate GGU Glycine U G GUC Valine GCC Alanine GAC Aspartate GGC Glycine C GUA Valine GCA Alanine GAA Glutamate GGA Glycine A GUG Valine GCG Alanine GAG Glutamate GGG Glycine G It is carrying arginine and will match with a CGU codon on the mRNA. It is carrying methionine and will match with a TAC codon on the DNA. It is carrying methionine and will match with a UAC codon on the mRNA. It is carrying tyrosine and will match with a UAC codon on the mRNA. Question 11 While the DNA in a human skin cell was being replicated, a single base was miscopied. What will be the most likely result of this for the cell in which it happened?.912.l.16.3> All the proteins the cell creates from the miscopied strand will do different jobs than the old ones. If the new sequence codes for the same amino acid as the original cell, it will function normally. Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded. Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides. Question 12 A ferret’s haploid number of chromosomes is 20. How would the number of chromosomes in the ferret’s body cells compare to the number of chromosomes in its gametes?.912.l.16.17> Its body cells would have 20 chromosomes, and its gametes would have 40 chromosomes. Its body cells and gametes would both have 40 chromosomes. Its body cells and gametes would both have 20 chromosomes. Its body cells would have 40 chromosomes, and its gametes would have 20 chromosomes. Question 13 A body cell is in the longest stage of its life cycle. The cell grows, synthesizing proteins and increasing in size. Eventually, the cell will grow too large to carry out normal activities. Which of the following is the best conclusion you can make about the life cycle of this cell?.912.l.16.14> The cell is close to the end of its life cycle, and a chemical signal will initiate cell death. The cell is ready to undergo mitosis, and a chemical signal will send the cell to prophase. The cell is in the G1 phase of interphase, and a chemical signal will send the cell to the S phase. The cell is in the S phase of interphase, and a chemical signal will move the cell to the G2 phase. Question 14 While mRNA strands are being created a sequence is sometimes miscopied. What is the best possible outcome for the cell should this take place?.912.l.16.5> The miscopied sequence codes for the same amino acids as the original sequence. The new sequence creates a protein that serves a different function from the original. The ribosomes will correct the mistake before the tRNA matches an amino acid to it. The mRNA will only be used to create non-critical proteins for the cell. Question 15 Over the last several decades, the scientific community has gathered a large amount of information regarding genetics and genetic variation. What are two main sources that lead to increased genetic variation?.912.l.15.15> Selective breeding Gamete mutations Recombination Genetic drift • Show less
