Answer 1

To complete the mRNA sequence that will be formed from the given DNA sequence, we start by transcribing the DNA to mRNA. The DNA sequence provided is:

**DNA:** TAC CGC CCC

During transcription, adenine (A) in DNA pairs with uracil (U) in RNA, thymine (T) in DNA pairs with adenine (A) in RNA, cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C).

Now, let's transcribe the DNA sequence:

1. **TAC** (DNA) → **AUG** (mRNA)
2. **CGC** (DNA) → **CGC** (mRNA)
3. **CCC** (DNA) → **GGG** (mRNA)

So the complete mRNA sequence will be:

**mRNA:** AUG CGC GGG

Next, we will use the mRNA sequence to identify the corresponding amino acids using the codon chart:

1. **AUG** codes for Methionine (Met)
2. **CGC** codes for Arginine (Arg)
3. **GGG** codes for Glycine (Gly)

Putting it all together:

- **mRNA:** AUG CGC GGG
- **Amino Acids:** Methionine - Arginine - Glycine

Here’s the final response:

- **mRNA:** AUG CGC GGG
- **Amino Acid Sequence:** Met - Arg - Gly
