The DNA replication for the sequence TCGAT would be:

AGCTA

Here's why:

* DNA replication is the process of creating a copy of a DNA molecule. It follows the base pairing rules:

* A (adenine) pairs with T (thymine)

* G (guanine) pairs with C (cytosine)

* The original strand: TCGAT

* The complementary strand: AGCTA
