3, AAA TGC GCG ATA 5' is the sequence of nucleotides on a gene after transcription the mRNA formed against it and the sequence of bases in the corresponding binding anticondons will be
(a) UUU ACG CGC UAU and AAA UGC GCG AUA
(b) UAU CGC GCA UUU and AUA GCG CGU AAA
(c) UUU ACC TUG UAU and AAA UGG UAC AUA
(d) UAU GUT CCA UUU and AUA CAU GGU AAA

Options

A. UU ACG CGC UAU and AAA UGC GCG AUA
B. UAU CGC GCA UUU and AUA GCG CGU AAA
C. UUU ACC TUG UAU and AAA UGG UAC AUA
D. UAU GUT CCA UUU and AUA CAU GGU AAA

Answer

To solve the question, we need to follow these steps:

### Step 1: Identify the given nucleotide sequence
The given nucleotide sequence is:
3' AAA TGC GCG ATA 5'

### Step 2: Transcribe the nucleotide sequence into mRNA
During transcription, the DNA sequence is used to create mRNA. The mRNA is synthesized in the 5' to 3' direction, and the base pairing rules are as follows:
- Adenine (A) pairs with Uracil (U) in RNA (instead of Thymine (T) in DNA)
- Thymine (T) pairs with Adenine (A)
- Cytosine (C) pairs with Guanine (G)
- Guanine (G) pairs with Cytosine (C)

Given the DNA sequence:
3' AAA TGC GCG ATA 5'

The complementary mRNA sequence (5' to 3') will be:
5' UUU ACG CGC UAU 3'

### Step 3: Determine the corresponding anticodons
Anticodons are complementary to the mRNA codons and are also read in the 3' to 5' direction. The mRNA sequence we obtained is:
5' UUU ACG CGC UAU 3'

Now we will find the anticodons:
- For UUU, the anticodon is AAA
- For ACG, the anticodon is UGC
- For CGC, the anticodon is GCG
- For UAU, the anticodon is AUA

Thus, the complete sequence of anticodons will be:
3' AAA UGC GCG AUA 5'

### Step 4: Match with the given options
Now, we will compare our results with the provided options:
- (a) UUU ACG CGC UAU and AAA UGC GCG AUA
- (b) UAU CGC GCA UUU and AUA GCG CGU AAA
- (c) UUU ACC TUG UAU and AAA UGG UAC AUA
- (d) UAU GUT CCA UUU and AUA CAU GGU AAA

The correct answer is option (a) which matches our results.

### Final Answer:
The mRNA formed is 5' UUU ACG CGC UAU 3' and the corresponding binding anticodons are 3' AAA UGC GCG AUA 5'.
