Question

Explain why TUS is the only replication protein that is sequence-specific?

Short answer

TUS also known as terminus utilization substance is a protein that binds to terminator sequences.

Step-by-step solution

TUS is the only replication protein that is sequence-specific

TUS acts as a counter helicase when it comes in contact with an advancing helicase.

TUS is sequence-specific and binds to terminator sequences.

Role of TUS

The bound TUS protein effectively halts. DNA polymerase movement TUS help in ending DNA replication in prokaryotes.

Thus, TUS is the only replication protein that is specific for sequences
