Answer 1

Answer is DNA replication

ECM extra cellular matrix consist of network of polysacharides and proteins secreted by the cell, proption of which varry depending on the tissue type. This include collagen, elastin, glyco proteins, fibronectin, laminin etc. Componenets of ECM linked to each other through cell adhesion molecules.

ECM serve as reservoir for signalling molecules that regulate cell dision, cell differentiation and cell motility. ECM proteins bind to growth factors (GFs) and interact with cell surface receptors to elicit cellular signalling and regulate gene transcription.

While ECM has no direct role in DNA replication which occur inside nuclues.
