, Trace file - this depicts the raw results of automated sanger sequencing.
Typically includes lots of colored humps that represent each nucleotide


Base call - the nucleotide at a given position in your DNA sequence
according to the results of automated sanger sequencing


Phred score - a measure of the quality of the identification of nucleobases
generated by automated DNA sequencing

Consensus Sequence - combination of trimmed for and reverse DNA
sequences that are typically more accurate than each sequence alone

Accession Number - unique identifier # given to each sequence in the
BLAST database


BLAST - basic local alignment search tool ; used to find matching DNA
sequences from a database

MUSCLE- an alignment of multiple DNA sequences that allow you to
visualize similarities and differences between the DNA sequences

, original research that is communicated "first-hand" by the people who
collected and analyzed the data = primary literature

communicated "second-hand" by people who did NOT collect or analyze
the original data = secondary literature

"third-hand" information that is typically written by non-experts, often lacks
citations, often prone to generalizations and simplifications, and not
typically peer reviewed = tertiary literature

Roughly 70% of the American population eats avocados at least once each
year, so the potential exposure of the populace to contaminants in
avocados is widespread (WHO, 2012). = why the area of study is important
(hook)


Nonetheless, little research has been done with regard to the uptake of
trace metals by avocados during their growth (Haas et al. 2019). = why past
work is inadequate

The proposed research would address this problem by making the first
detailed examination of links between groundwater and concentrations of
trace metals in avocados. We will test the hypothesis that heavy metal
concentrations in groundwater affect their concentrations in avocados. =
your question/aim/hypothesis




What does peer-reviewed mean?

Other experts in the field have verified the integrity of the information




The following are examples of questions/studies that students designed in previous
semesters. Which of the following is NOT a good question for DNA barcoding to
address?
