What is the sequence of the template DNA used in the sequencing reactions below?
3’ATCAGAGCTATAGCAGTGC 5’
If the two oligonucleotides below are allowed to anneal and DNA polymerase and all
substrates (4 dNTPs, etc.) are added to the mix, what will the first three nucleotides
incorporated in DNA be? 5’ ACT 3’
5’ ATCCTGGACACTGTACCATCGGRACCAATCACAGGTCCTTACAGT 3’
5’ GGACCTGTGA 3’. What is the sequence of the left strand of the DNA shown
below? 5’ ACTG 3’
What sort of mutation occurred in the mutated sequence in the table below?
A transition leading to a missense
mutation. The following eukaryotic
DNA is transcribed into RNA and the mRNA transcript is translated into protein.

The following eukaryotic DNA (same as above) is
transcribed into RNA and the mRNA transcript is translated into protein. What is the
sequence of the protein translated from this mRNA? N – Met-Ala-Leu – C. What does
lactose binding to the lac operon repressor do? When lactose is present, the lac
repressor loses its ability to bind DNA. (When lactose is not available, the lac repressor
binds tightly to the operator, preventing transcription by RNA polymerase).
Using the DNA sequence below, which new DNA sequence from 3’ to 5’ incorporates a
silent mutation? DNA 3’ TACATAACCATT 5’. DNA 3’ TACATTACCATT 5’. The
following prokaryotic DNA is transcribed into RNA and the mRNA transcript is
translated into protein. What region of this prokaryotic DNA sequence will be
transcribed into mRNA? 54-119
The following prokaryotic DNA (same as
above) is transcribed into RNA and the mRNA transcript is translated into protein.
Where is the 3’ UTR? 87-119, Where is the 5’ UTR? 38-65
*What region of the mRNA contains the open reading frame that will be translated into
protein? 57-65. Babies in a hospital were switched at birth. Identify each mother’s baby.
Mother 1 and baby 2, Mother 2 and baby 3
