Answer:
The correct answer is A.) during transcription
Explanation:
The pairing during DNA replication and transcription is a little bit different. During replication, A pairs with T, T with A, C with G, and G with C. In transcription T is replaced by U so when there is nucleotide adenine is present in the DNA sequence than uracil will be added against it as complementary nucleotide in mRNA during transcription.
So here 5'-GAT-3' nucleotide sequence is present in DNA and after transcription the nucleotide sequence will be 5'-CUA-5' because U is added against A during transcription. Therefore the correct answer is A.
Answer:
a. 50%
Explanation:
<em>BRCA1 genes is a tumor supressor gene whose harmful mutation can cause hereditary breast ovarian cancer syndrome in both males and females. The BRCA actually stands for breast cancer.</em>
