Questions & Answers {Grade A} 100%
Correct (Verified Solutions)- Portage
Learning
Mitosis - Correct answer the division of genetic material; can be broken down into 5
subphrases (prophase, pro metaphase, metaphase, anaphase, and telophase)
Cytokinesis - Correct answer the process of dividing the cell's cytoplasm
Origin of Replication - Correct answer located along the strands of DNA are short
nucleotides; the nucleotide sequence at each origin of replication encodes for a start
signal at which the process of replication will be initiated by proteins that recognize
and bind to those sequences
Helicase - Correct answer an enzyme that has the role of untwisting and separating
the helix parent strands at the replication fork
,Replication fork - Correct answer Y-shaped area where the DNA strands are beginning
to untwist
Replication bubble - Correct answer as the helices begins to separate the double
strands, a visible replication bubble forms that will expand as replication continues
along the strand
Single stranded binding proteins - Correct answer act as a wedge to keep the parent
strands separated and stabilized
Topoisomerase - Correct answer in the front of the fork and its function is to break the
hydrogen bonds and the nucleotide bases and it plays a role in rejoining the DNA
strands when replication is complete; it is able a stabilizing enzyme that reduces the
strain in the strands that occur during replication
RNA primers - Correct answer complementary to the parental DNA strand
, RNA - Correct answer single-stranded and contains sugar ribose and it does NOT have
a thymine but a uracil
Primase - Correct answer enzyme that facilitates the synthesis of an RNA primer by
using the unwound DNA strand as a template; it binds to the 3' end of the parent strand
and begins adding complementary RNA nucleotides as it moves toward the 5' end of
the parent strand
DNA polymerase - Correct answer enzymes that add nucleotides to the 3' end of the
existing chain via dehydration reactions
Triphosphate tail - Correct answer three phosphate group; has a negative charge
around it
Pyrophosphate - Correct answer will undergo hydrolysis reaction which splits the
molecule into two inorganic phosphates and energy is released in the process
