Mitochondrial dna is used to follow maternal inheritance and sequences on the y chromosome is used to follow paternal inheritance. why is it not practical to analyze paternal inheritance in this class?
a. because only men have a y chromosome, the women in the class wouldn't be able to participate. b. none of these are valid reasonsc. it's not impractical because y chromosome sequences are present in both men and women. d. because only men have a y chromosome, the men in the class wouldn't be able to participate. e. because only men have a y chromosome, the women in the class would contribute excess data.

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.
