The sequence that would be produced through transcription having sequence of original DNA strand ACGTAAGCT is UGCAUUCGA.
What is DNA?
- DNA stands for deoxyribonucleic acid.
- It is a long chain of polynucleotide.
- Each nucleotide consists of: deoxyribose sugar, phosphate group and nitrogenous bases (nitrogen-containing compound).
- Nitrogenous bases are of two types: Purines (consisting Adenine and Guanine) and Pyrimidine (consisting Cytosine and Thymine).
- Adenine pairs with Thymine by forming two hydrogen bonds whereas Guanine pairs with Cytosine by forming three hydrogen bonds.
What is RNA?
- RNA stands for ribonucleic acid.
- It is a long chain of polynucleotide.
- Each nucleotide consists of: phosphate group, ribose sugar and nitrogenous bases.
- Nitrogenous bases are of two types: Purines and Pyrimidines.
- Purines consists of Adenine and Guanine whereas Pyrimidines consists of Cytosine and Uracil (instead of Thymine).
- Adenine pairs with Uracil whereas Guanine pairs with Cytosine.
What is transcription?
- The process by which mRNA is produced from DNA sequence.
- Example: If the sequence of original DNA strand is ACGTAAGCT then the sequence of mRNA would be UGCAUUCGA.
Hence, the correct option is: B. UGCAUUCGA.
