Nitrogenous base
Phosphate group
Avery found that DNA was necessary and sufficient for
bacterial transformation. Which of the following experimental
results support this statement? Select all that apply. Correct
Answers Removal of DNA from cell extracts prevented
transformation
DNA alone will cause transformation to occur
Choose the answer that has the information flow of the central
dogma in the correct order. Correct Answers DNA,
transcription, RNA, translation, protein
Chromatin consists of: Correct Answers DNA and protein
DNA/RNA is the less stable molecule because: Correct Answers
RNA, because it has a 2'OH group
Each nucleosome contains: Correct Answers a histone octamer
composed of two copies of" H2A, H2B, H3 and H4
Genomics is the field dedicated to the study of: Correct Answers
DNA on a cellular scale.
, Hershey and Chase's experiment demonstrated that DNA is the
hereditary information. Which experimental result allowed them
to conclude this? Correct Answers Radioactive phosphorus was
found in the bacterial pellets.
In the following pathway, mutation of enzyme II would result in
the accumulation of __________ and the mutant would require
__________ in the media in order to grow. Correct Answers
ornithine, citrulline

Successive nucleotides of a DNA chain are joined by: Correct
Answers Phosphodiester bond between the 3 carbon of one
nucleotide and the 5 carbon of the next
The carbons of the pentose group of DNA and RNA nucleotides
are identical except for: Correct Answers The functional group
attached to C2
The contacts between the DNA and the histones of the
nucleosome are: Correct Answers Mainly between the
conserved histone folds and the phosphate backbone of the DNA
helix.
The first evidence for nucleosome formation came from
digesting chromosomal DNA with a non-specific nuclease. Gel
electrophoresis of the DNA after the reaction revealed: Correct
Answers A ladder of protected fragments about 200 bp apart.
