80. This enzyme unwinds the double stranded DNA during replication
81. The DNA forms-this area- after the two strands of the double helix have separated, or unzipped, during the process of DNA replication
82. These small proteins bind to the strand and temporarily form hydrogen bonds with the base pairs
83. This strand is continuous and is replicated toward the replication fork
84. The small fragments of DNA are made discontinuously away from the replication fork
85. Each NEW strand has to be replicated in this direction
86. This enzyme replicates the new strand
87. A small piece of RNA is added by this enzyme to the beginning of each new strand
88. This enzyme relieves the coil during the unwinding of the DNA strand, unwinds the strand in the opposite direction.
89. The 3’ of the DNA can not be replicated- this is known this conundrum?
90. Region of repetitive nucleotide sequences at each end of a chromatid, added to protect the gaps at the 3’ end that can’t be synthesized by polymerase.
91. Cancer cells have this over active enzyme- immortal
92. Bacteria cells have DNA of this shape
93. Eukaryote cells have DNA of this shape
94. Eukaryotes cells have multiple __________________, a start site of the genome being copied
95. Nonstructural genes are able to splice themselves using this component that behaves like and enzyme and has catalytic properties.

Question
Answer
Justification
80. This enzyme unwinds the double stranded DNA during replication
Helicase
Helicase is enzyme involved in unwinding of DNA
81. The DNA forms-this area- after the two strands of the double helix have separated, or unzipped, during the process of DNA replication
Replication fork
Replication fork contains unwinded DNA
82. These small proteins bind to the strand and temporarily form hydrogen bonds with the base pairs
Single stranded binding proteins
SSB proteins binds to ssDNA and keeps DNA unwinded
83. This strand is continuous and is replicated toward the replication fork
Leading strand
DNA synthesis on 5’-3’ strand
84. The small fragments of DNA are made discontinuously away from the replication fork
Okazaki fragments
Small DNA strands synthesized on 3’-5’ strand
Kindly ask remaining questions as separate post!!
