To complete the mRNA sequence based on the provided DNA sequence "TAC CGC CCC", we need to transcribe the DNA to mRNA.
The rules for transcription are:
- Adenine (A) in DNA pairs with Uracil (U) in RNA.
- Thymine (T) in DNA pairs with Adenine (A) in RNA.
- Cytosine (C) in DNA pairs with Guanine (G) in RNA.
- Guanine (G) in DNA pairs with Cytosine (C) in RNA.
Now, we will transcribe the given DNA sequence:
- TAC → AUG
- CGC → GCG
- CCC → GGG
So the complete mRNA sequence is: AUG GCG GGG
Now we will identify the amino acids corresponding to the mRNA codons:
- AUG codes for Methionine (Met)
- GCG codes for Alanine (Ala)
- GGG codes for Glycine (Gly)
Putting it all together:
mRNA: AUG GCG GGG
Amino acid: Met Ala Gly
So the final answer is:
- mRNA: AUG GCG GGG
- Amino acid: Met Ala Gly
