During Hfr conjugation, what is the order of DNA transfer from an Hfr cell to a recipient cell?
- First, chromosomal genes; next, a part of F factor; lastly, the remaining part of F factor
- First, a part of F factor; next, the remaining part of F factor; lastly, chromosomal genes
- First, a part of F factor; next, chromosomal genes; lastly, the remaining part of F factor (correct)

What is the significance of colinearity in prokaryotes?
What is the significance of colinearity in prokaryotes?
- It ensures that all genes are expressed in a linear fashion
- It allows for a direct translation from nucleotide sequence to amino acid sequence (correct)
- It determines the linear order of nucleotides in a gene based on amino acid structure
- It prevents non-informational DNA sequences from interrupting gene continuity
What distinguishes a specialized transducing phage from a generalized transducing phage?
What distinguishes a specialized transducing phage from a generalized transducing phage?
- Specialized phages can transfer genes only through lytic cycle
- Generalized phages have the ability to cut the bacterial chromosome into pieces
- Generalized phages can only transfer genes from a particular region of the bacterial chromosome
- Specialized phages can only transfer DNA derived from any part of the bacterial chromosome (correct)
