Coco12 said:A portion of an mRNA molecule has the sequence CCUAGGCUA. What is the sequence of the anti sense strand of the corresponding DNA molecule?
The anti sense strand is the coding strand. The 3' to 5' strand from which mRNA builds. Does that mean the sequence would be backwards?
epenguin said:First part: write out your reasoning for thinking that.
2nd part: are all bases the same in RNA and DNA?
Coco12 said:RNA has uracil instead of thymine
Coco12 said:So it would the complementary base pairs : GGATCCGAT?
epenguin said:Right.
are you unsure? This is not for a guess, just a test of knowing how mRNA is synthesised, and the conventions. Do a little picture if nec and don't be afraid to attach 3' and 5' signs to your strand ends.

Coco12 said:Just to clarify if the question said sense strand instead of anti , it would be the same sequence given except it would have thymine instead of uracil right?
DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions for all living organisms. It is made up of four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
The anti-sense strand of DNA is the complementary strand to the sense strand. It has the opposite base sequence and is used as a template for creating mRNA during transcription.
The CCUAGGCUA mRNA molecule is a specific messenger RNA (mRNA) molecule that is created during the process of transcription. It contains a sequence of bases that is complementary to the anti-sense strand of DNA.
The anti-sense strand plays a crucial role in gene regulation by serving as a template for creating mRNA. This mRNA then carries the genetic information from the DNA to the ribosomes, where it is used to produce proteins. By controlling the production of mRNA, the anti-sense strand helps regulate which genes are expressed and which are not.
The sequence of the anti-sense strand is determined by the sequence of the sense strand. Due to the complementary base pairing rule, the sequence of the anti-sense strand will always be the opposite of the sense strand. This sequence is unique to each gene and is essential for proper gene expression and protein production.
