Question

If the sequence of bases of the. Mrna Coden is AU. What would be the sequence of bases on the opposite strand assembled by the t? Rna 1U AAA 2T. AA3UA for ATT. T

Answer 1

To decipher your question, let's break it down step by step regarding mRNA, tRNA, and the complementary base pairing.

1. You have a base sequence of mRNA indicated as "AU".
2. mRNA is complementary to the DNA template strand, and it is synthesized based on the template strand.

If the mRNA sequence is **AU**, this indicates that the DNA template strand would have the complementary bases.

- For **A** in mRNA, the complementary DNA base would be **T** (A pairs with T).
- For **U** in mRNA, since uracil doesn't exist in DNA, it corresponds with **A** (U pairs with A from the template).

Hence, for the mRNA "AU", the corresponding part of the DNA template strand would be **TA**.

Now, if you are referring to the tRNA that would bind to this mRNA (which has anticodons that are complementary to mRNA codons), the tRNA anticodons would be:

- For the mRNA codon **AU**, the complementary tRNA anticodon would be **UA**.

Putting this all together:
- mRNA: AU
- DNA Template Strand: TA
- tRNA Anticodon: UA

Now, regarding the sequence you mentioned, if you provide clear codons (the sets of three bases), I can assist you further based on that information. However, it seems there are some extra notations ("1U AAA 2T. AA3UA for ATT. T") that might need clarification to assist you accurately.

If you complete or clarify your question, I would be happy to help!
