DNA Sequence for Anti-Sense Strand of CCUAGGCUA mRNA Molecule

In summary, the anti sense strand of the corresponding DNA molecule to an mRNA molecule with the sequence CCUAGGCUA would have the sequence GGATCCGAT, with thymine instead of uracil if it was the sense strand. This is due to the complementary base pairing between adenine and uracil in RNA, which is replaced by adenine and thymine in DNA.

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?

First part: write out your reasoning for thinking that.

2nd part: are all bases the same in RNA and DNA?

RNA has uracil instead of thymine

So it would the complementary base pairs : GGATCCGAT?

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.

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?

Is that the sequence complementary to the mRNA?

yes I think that's a correct deduction.
 

Related to DNA Sequence for Anti-Sense Strand of CCUAGGCUA mRNA Molecule

What is DNA sequence?

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).

What is the anti-sense strand of DNA?

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.

What is the CCUAGGCUA mRNA molecule?

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.

What is the significance of the anti-sense strand in gene regulation?

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.

How is the sequence of the anti-sense strand determined?

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.
