Griffith's experiment discovered bacterial transformation which in his experiment means:

1.	A mutation in the R strain made them virulent.
2.	A mutation in the S strain made them non-virulent.
3.	A rough strain passed genetic information to a smooth strain.
4.	A smooth strain passed genetic information to a rough strain.

All the following will not be applicable to DNA replication in prokaryotes except:
1. It begins at several places along the chromosome.
2. It begins at the origin and travels in both directions.
3. It begins at the origin and travels around the chromosome back to the origin.
4. It begins at a GC rich region of the chromosome.

Avery, MacLeod, and McCarty used DNase in their experiment because:

The analysis of viral nucleic acid reveals that it contains adenine 21%, guanine 31%, cytosine 23%, and some unexpected base 19%. What will be true for this virus?

The bacterial DNA is mainly composed of:
1. Ori sequences.
2. Structural gene sequences.
3. Intergenic regions.
4. Introns.

All the following structures in a eukaryotic chromosome are composed of DNA except:

A genome will be best defined as:
1. All the information in plasmids of a bacterium.
2. A homologous pair of chromosomes.
3. The complete DNA sequences in a diploid zygote.
4. All the DNA contained in a human gamete.

When DNA is replicated the first nucleotides are added by:
1. DNA primase
2. DNA polymerase III
3. DNA polymerase II
4. DNA ligase

A deoxyribonucleotide contains:

Constitutive heterochromatin includes:
1. The Barr body.
2. A region of active gene expression.
3. Telomeres.
4. Both 1 and 2.
