So, referring to this link I reference : https://en.bitcoin.it/wiki/Transactions

I just want to know how this will look with a coinbase transaction. I understand the basis of the reward system, the miners and the solving of the block's hash through SHA-256 and all continuous transaction following but since there is no input in coinbase transaction is there still something to be represented for the input.

Referring to the link above, will there be nothing following the previous tx, index and scriptsig?

This is given as the input for a tx:

Input:
Previous tx: f5d8ee39a430901c91a5917b9f2dc19d6d1a0e9cea205b009ca73dd04470b9a6
Index: 0
scriptSig: 304502206e21798a42fae0e854281abd38bacd1aeed3ee3738d9e1446618c4571d10
90db022100e2ac980643b0b82c0e88ffdfec6b64e3e6ba35e7ba5fdd7d5d6cc8d25c6b241501

Will the coinbase transaction look like this:

Input:
Previous tx:
Index: 0
scriptSig:

Or will something be represented in each section including previous tx, Index and scriptSig?If so, what?
 
It not, what? I just need something very explicit to know what the eventual reference will be. Basically, since BTC are are a series of signatures there must be a first reference point for the signature. Is it just some code originating from the block of the coinbase transaction? If it is, what is that reference? and when we trace a bitcoin back to its creation (or prior to the original possessors signature) what exactly will it look like?

Also, on another note, is an address just a public-key?
