  • mRNA Sequence Transcription: Decoding DNA to RNA - A Step-by-Step Guide
    Here's how to determine the mRNA sequence from the given DNA sequence:

    Understanding the Process

    * DNA to RNA: DNA contains the genetic blueprint, but it's RNA that carries the instructions to build proteins. The process of making RNA from DNA is called transcription.

    * Base Pairing: The key is understanding how the bases in DNA pair with those in RNA:

    * Adenine (A) in DNA pairs with Uracil (U) in RNA

    * Thymine (T) in DNA pairs with Adenine (A) in RNA

    * Guanine (G) in DNA pairs with Cytosine (C) in RNA

    * Cytosine (C) in DNA pairs with Guanine (G) in RNA

    Let's Transcribe:

    1. Original DNA sequence: aaacaggtccca

    2. Transcribe each base:

    * A --> U

    * A --> U

    * A --> U

    * C --> G

    * A --> U

    * G --> C

    * G --> C

    * T --> A

    * C --> G

    * C --> G

    * C --> G

    * A --> U

    3. The mRNA sequence is: UUUGUCCAGGGU
