Biology Semester 2 Final Review

Any change in the nucleotide sequence of the DNA of a gene is called

• codon

• anticodon

• translation

• mutation

Which of the following sequences best describes the flow of information that takes place when a gene directs the synthesis of a protein?

• protein --> RNA --> DNA

• DNA --> mRNA --> protein

• DNA --> amino acid --> RNA --> protein

• DNA --> tRNA --> mRNA --> protein

Select the correct complementary sequence of DNA for

TAC ACG TTA AGC ACT .

• ATG TGC AAT TCG TGA

• TGC AAT TCG ACG UGA

• UGC AAT UCG TGA

• AUG TGC AAT UCG UGA

A codon is a triplet code found on

• mRNA

• tRNA

• DNA

• rRNA

What is the end product of Replication?

• two new strands of new DNA.

• single strand of DNA

• for strands of DNA

• two strands of DNA each with 1 parent strand and new strand.

A section of DNA that codes for a protein is called a-

• gene

• cell

• chromosome

• nucleus

Transcribe this strand of DNA.

After meiosis II, which of the following is true about the cells that are produced?

• Four cells are produced. They are identical to each other and each contains half the number of chromosomes that the parent cell has.

• Four cells are produced. Each is unique and contains half the number of chromosomes that the parent cell has.

• Four cells are produced. Each is unique and contains the same number of chromosomes that the parent cell has.

• Two cells are produced. Each is unique and contains the same number of chromosomes that the parent cell has.
