Question

directions: drag the nitrogenous bases to the correct locations on the image. each base can be used more than once, but not all bases must be used. sections of a dna strand and an incomplete rna strand are shown in the diagram below. during rna transcription, a dna template strand is used to produce an rna strand. simulate the process of transcription by adding the remaining complementary nitrogenous bases to the rna strand.

Explanation:

Step1: Recall base - pairing rules

In RNA transcription from DNA, adenine (A) in DNA pairs with uracil (U) in RNA, thymine (T) in DNA pairs with adenine (A) in RNA, cytosine (C) in DNA pairs with guanine (G) in RNA, and guanine (G) in DNA pairs with cytosine (C) in RNA.

Step2: Match bases

Working from the given DNA strand, we find the complementary RNA bases one - by - one.

Answer:

Match the bases according to the rules: A - U, T - A, C - G, G - C for each base in the DNA strand to form the RNA strand. Without seeing the specific DNA sequence in the image clearly enough to list out the full RNA sequence, the general process is as described above. If the DNA sequence is, for example, ATGCTA, the RNA sequence would be UACGAU.
