It determines protein structure.
It is important for cell to copy DNA without making mistake because the DNA contain genetic code in the form of nucleotide base pair sequence, if those sequence get wrong then the DNA code for wrong gene i.e. there will be a mutation which can be lethal or dangerous.
No DNA sequence wont have U (uracil), so it is an RNA sequence!
The start codon is the point at which a DNA sequence starts. It is important because a ribosome begins translating a sequence of RNA into amino acids.

BBC is the DNA in a MRNA sequence. This is part of the body.
gene sequence: DNA sequence ( its the same thing)
With the sequence GCAGCGGAT of DNA CGTCGCCTA will form.
If the DNA sequence is ACT, the complimentary mRNA sequence would be UGA
