WGU D312 A P 1 Exam Questions With
Outlined And Correct Answers
\Q\.Nucleus - ANSWER-✔- cell's central organelle/largest organelle
- contains the cell's DNA
- control center of the cell because it stores all of the genetic instructions for manufacturing
proteins
\Q\.nuclear envelope - ANSWER-✔- two adjacent lipid bilayers with a thin fluid space in
between them and nuclear pores on them
\Q\.nuclear pores - ANSWER-✔tiny passageway for the passage of proteins, RNA, and solutes
between the nucleus and the cytoplasm
\Q\.pore complexes in the nuclear envelope - ANSWER-✔line the nuclear pores and regulate
the passage of materials into and out of the nucleus.
\Q\.Nucleoulus - ANSWER-✔produces ribosomes when the correct RNA is manufactured
\Q\.Chromatin - ANSWER-✔a substance consisting of DNA and associated proteins
\Q\.Histone - ANSWER-✔proteins that associate with DNA in the nucleus to form chromatin
\Q\.Nucleosome - ANSWER-✔a single, wrapped DNA-histone complex
, \Q\.Chromosomes - ANSWER-✔condensed form of chromatin
\Q\.Proteome - ANSWER-✔full complement of proteins
\Q\.Gene - ANSWER-✔a functional segment of DNA that provides the genetic information
necessary to build a protein
\Q\.gene expression - ANSWER-✔dictates the structure and function of a cell by determining
which proteins are made
\Q\.DNA replication - ANSWER-✔the copying of DNA that occurs before cell division can take
place
\Q\.DNA replication steps - ANSWER-✔initiation, elongation, termination
\Q\.Initiation - ANSWER-✔The two complementary strands are separated. Special enzymes,
untwist and separate the two strands of DNA
\Q\.Elongation - ANSWER-✔Each strand becomes a template along which a new
complementary strand is built. DNA polymerase brings in the correct bases to complement the
template strand, synthesizing a new strand base by base. A DNA polymerase is an enzyme that
adds free nucleotides to the end of a chain of DNA, making a new double strand. This growing
strand continues to be built until it has fully complemented the template strand.
\Q\.Termination - ANSWER-✔Once the two original strands are bound to their own, finished,
complementary strands, DNA replication is stopped and the two new identical DNA molecules
are complete.
