You're interested in the genetics of earlobe shape on your campus. free (unattached) earlobes are caused by a dominant allele. the attached earlobe phenotype is caused by a recessive allele. individuals with free earlobes have either a homozygous genotype or a heterozygous genotype. assuming that your college campus is a stable population, what calculation would you use to determine the percentage of students who have a heterozygous genotype for earlobe shape? a) calculate the percentage of people who have free earlobes. b) calculate the percentage of people who are homozygous-dominant for free earlobes. c) calculate the percentage of people who have attached earlobes. d) calculate the percentage of people who carry the recessive allele.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
