LTE: Are the demodulation reference symbols modulated using SC-FDMA like other PUSCH symbols or using OFDM?

Are the demodulation reference symbols modulated using SC-FDMA like other PUSCH symbols or using OFDM. I have seen in a couple of places that OFDM is used for the DRMS, but I cannot find anything about it in 3GPP TS 36.211.

Any pointer would be appreciated?

LTE: Why SC-FDMA has PAPR lower than OFDMA?

PAPR is the major disadventage of OFDMA which require high resolution D/A and A/D or increasing Transmission Power.
I know that SC-FDMA used on Uplink becuase it has lower PAPR than OFDMA. On downlink direction, the high PAPR Problem of OFDMA solved by increasing eNB transmission power. This solution cannot be implemented on Uplink direction because UL is power limited link. so SC-FDMA used on UL instead of OFDMA, but why? why SC-FDMA has LOWER PAPR

Why SC-FDMA is not used for downlink?

I know the reason why OFMDA cannot be used for the uplink but I wonder why SC-FDMA is not used for the downlink. It is still a form of OFDMA technology.

Is it practically possible to deploy SC-FDMA in downlink for LTE?

SC-FDMA is kind of a variant of OFDMA so I wanted to know is it practically possible to deploy SC-FDMA for multiple access in downlink in LTE-A and what will be the negatives of deploying SC-FDMA for downlink instead of OFDMA?
