Red blood cells contain the hemoglobin protein which is a carrier of oxygen. In sickle cell anemia, the hemoglobin present in red blood cells becomes abnormal and sickle shaped. Abnormal hemoglobin cannot carry as much oxygen as normal hemoglobin. The sequences given show sections of the DNA sequence that produce both the normal and abnormal types of hemoglobin.

Which amino acids are coded for by the abnormal DNA?

• histidine, leucine, valine

• histidine, threonine, valine

• proline, valine, glutamic acid

• proline, leucine, glutamic acid

• Insertion

• Substitution

The diagram shows a single DNA strand.

What would happen if thymine (T) was replaced by adenine (A)?

• A nondisjunction would occur.

• A gene mutation would occur.

• A segregation would occur.

• Crossing-over would occur.

When a strand of DNA was replicated, one base was left out. Why would this be more damaging than if the base was only changed?

• The process stops and must restart at the beginning after the new sequence of DNA has been read.

• The missing base would leave a hole in the new DNA strand, causing the structure to be unstable.

• The rest of the DNA cannot be read, as it would recognize that the number of bases changed.

• The codons shift one letter for all bases after the mutation, changing all of them as well.

What is the role of mRNA during protein synthesis?

• to bind to protein molecules and form ribosomes

• to carry out the termination of a polypeptide chain

• to carry genetic information from the DNA in the nucleus to the ribosomes for translation

• to recognize a specific codon and to deliver the corresponding amino acid to the ribosome

The diagram shows a process that occurs in most cells.

What is the significance of this process?

• It creates copies of the cell's genetic code for daughter cells.

• It enables the cell to produce proteins for cell division.

• It allows the cell to identify and repair errors in the genetic code.

• It produces strands of mRNA and tRNA for protein synthesis.

• DNA --> proteins --> mRNA --> traits

• mRNA --> DNA --> proteins --> traits

• mRNA --> proteins --> DNA --> traits
