During transcription, the nucleotide sequence of the nascent RNA is most similar to that of the: sensestrand, antisense strand, template strand, or non-coding strand.

The answer is sense strand.
Nascent RNA is immediately formed RNA, can someone elaborate?
But...isn't the sense strand the same as the template strand?
This is their explanation:

During transcription, the nucleotide sequence of the nascent RNA is most similar to that of the sense strand. Several synonyms are used to describe the complementary nucleotide sequences of double stranded DNA undergoing transcription. After the DNA double helix is opened, the single stranded DNA from which the RNA is directly transcribed is referred to as the template, antisense, or non-coding strand. The single stranded DNA strand that does not serve as a template for RNA transcription is known as the non-template, sense, or coding strand. The nucleotide sequence of the nascent RNA is the same as the sense strand except that U pairs with A instead of T.

Hi, check the DAT Discussions forum. I think you will get more assistance there than here, and good luck on your DAT! :D
 
DNA has template/Antisense/non-coding strand and nontemplate/sense/coding strand.
Example
Strand1(Anti- sense/template): 5' - GTACCACAG - 3'
Strand2(sense/nontemplate): 3' - CATGGTGTC - 5'
RNA strand transcribed from template: 3' - CAUGGUGUC-5'
As you can see sense strand has same sequence as RNA being transcribed. Also think of sense as the one being similar to the strand being translated.
Hope this helps.
