DNA Sequence 5'- AGT AAC GGC AGA CTT CTC CAC AGG AGT CAG GTG CAC CAT -3' mRNA Sequence: 5'- ........................................................-3' Nucleotides: ACGTU

Respuesta :

Answer:

5'- UCA UUG CCG UCU GAA GAG GUG UCC UCA GUC CAC GUG GUA -3'

Explanation:

As we know there are four nitrogenous bases  in DNA double helix, they are divided into two categories Purines and Pyrimidines.  

Purines:

Adenine (A) and Guanine (G)

Pyrimidines:

Cytosine (C) and Thymine (T)

Note: In case of RNA Thymine will be replaced with Uracil (U)

During Transcription, A DNA sequence is copied into messenger RNA (mRNA). As a first step the double helix molecule of DNA will unwind and one of the strands will be used as template. RNA polymerase moves along the template strand and synthesize mRNA.
