In the datura plant, purple flower color is controlled by a dominant allele p. white flowers are found in plants homozygous for the recessive allele p. a purple-flowered datura plant is self-fertilized, and its offspring are 27 purple-flowered plants and 9 white-flowered plants. if the 27 purple-flowered plants are self-fertilized, how many of the 27 would you expect to segregate both purpled-flowered and white-flowered plants in their offspring?

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.
