Write the sequence of pre-mRNA produced from the following DNA informational strand.
                                                           5’ AATCAGTGACGT 3’

Suppose a mutation occurs in the DNA section in problem 17.89, and the first base in the parent chain, adenine, is replaced by guanine.

b. Using the new strand that results from this mutation, write the order of bases in the altered mRNA.

List the mRNA bases that complement the bases A, T, G, and C in DNA.

The sequence of bases in a DNA template strand is 5'GGCTTATTGCCA3'. What is the corresponding mRNA produced?

The following portion of DNA is in the template DNA strand: 3'TGT|GGG|GTT|ATT5'

b. Write the anticodons corresponding to the codons on the mRNA.

If the sequence T-A-C-C-C-T appears on the informational strand of DNA, what sequence appears opposite it on the template strand? Label your answer with 3′ and 5′ ends.

What mRNA base sequences are complementary to the following DNA template sequences? Be sure to label the 5′ and 3′ ends of the complementary sequences.

a. 5′ CAT GCT CTA CAG 3′

Match each of the following processes (1 to 5) with one of the items (a to e):

2. transcription

a. amino acids are linked together

b. RNA template is used to synthesize DNA

c. helicase unwinds DNA

d. genetic information is transferred from DNA

e. sticky ends join new DNA segment
