During agarose gel electrophoresis, why does DNA move through the gel when electric current is applied?
because DNA is negatively charged
because a charged chemical from the loading buffer is bound to the DNA
because DNA is positively charged
because DNA absorbs electricity
If mature eukaryotic MRNA is hybridized with its corresponding genomic DNA template strand and
visualized by electron microscopy, two types of structures are seen: RNA:DNA double-stranded
heteroduplexes and single stranded DNA loop structures, as shown in the diagrams below. What do you
think these single stranded DNA loops represent?
(a) Micrograph of DNA-RNA
hybrid
(b) Interpretation of micrograph
Single-stranded
DNA only
Single-stranded DNA
base paired with MRNA
Select one:
а. Exons
b. Introns
c. 5' UTR
d. 3' UTR
e. promoter
Explain how agarose electrophoresis separates DNA fragments. Why does a smaller DNA fragment move
faster than a larger one?

This experiment determines: how many copies of gene X there are in liver cells. if the gene X is translated in liver cells. if gene X has a point mutation in liver cells. the chromosomal location of gene X. the length of the transcript of gene X.arrow_forward
