A bacterial cell with faulty RNA polymerase would not be able to carry out a) DNA replication b) double helix formation c) DNA supercoiling d) transcription 3. R plasmids are of particular concern to humans because they can: a) interfere with the human immune cells b) increase reproductive capabilities in bacteria c) transfer antibiotic resistance between bacteria d) contain genes that can code for bacterial toxins 4. Prokaryotic cells typically have which type of genome? a) double strand, straight DNA strand b) double strand, double helix DNA strand c) single strand, double helix DNA strand d) single strand, circular DNA strand 5. Unlike most prokaryotes, Eukaryotic RNA contains a) R sites b) terminators c) introns d) exons ic RNA containsthat must be removed during processing.

Answer 1

1. Option B is correct. Dna polymerase is responsible for adding nucleotides to the DNA molecule during DNA replication. DNA polymerase adds nucleotides in the 5'-3' direction.

2. Option d is correct. Bacterial cell with faulty RNA polymerase would not be able to carry out transcription.

3. Option C is correct. R plasmids are of particular concern to humans because they can transfer antibiotic resistance between bacteria.

4. Option d is correct. Prokaryotic cells typically have single stranded circular DNA strand.

5. Option C is correct. Unlike most prokaryotes eukaryotic RNA contains introns that must be removed during processing.
