Josh is assigned a project in class to make a strand of m-rna from dna. the dna code that he has been assigned is cgg tcg agt gat. what would be the correct code for josh to use in his transcription

The code will be GCC AGC UCA CUA

Explanation:

The mRNA is produced complementary to the DNA strand.  The Adenine nucleotide pairs with the Uracil (instead of thymine) in m RNA. The Guanine base pairs with Cytosine. This pairing will result in the formation of the mRNA strand. Once the strand is synthesized, it moves out of the nucleus.

Hence, as the sequence of the above DNA code is CGG TCG AGT GAT, the mRNA produced will have the code  GCC AGC UCA CUA.
