73) Carbon atoms are unique in their ability to form chains of varying sizes.
Which statement correctly describes a reason for the very large variety of these chains?
A)
Single bonds between two carbon atoms are non-polar in nature.
B)
Carbon has the towest electronegativity among-the-common elements.
The bond strength of a single bond between two carbon atoms is large.
D)
The bonding between two carbon atoms can be either ionic or covalent.

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.

Give two examples of what would occur if one of the pairs did not match or had an extra chromosomes. explain how this might occur, and if it would be dangerous to the individual. fast.
