- a A short segment of DNA synthesized away from the replication fork on a template strand during DNA replication, many of which are joined together to make up the lagging strand of newly synthesized DNA.
- b A virus that infects bacteria; also called a bacteriophage.
- c Type of DNA replication in which the replicated double helix consists of one old strand, derived from the old molecule, and one newly made strand.
- d The less condensed form of eukaryotic chromatin that is available for transcription.
- e The cellular process that uses specific enzymes to remove and replace incorrectly paired nucleotides.
5 Multiple choice questions
- Site where the replication of a DNA molecule begins, consisting of a specific sequence of nucleotides.
- The new complementary DNA strand synthesized continuously along the template strand toward the replication fork in the mandatory 5'?3' direction.
- An enzyme that joins RNA nucleotides to make the primer using the parental DNA strand as a template.
- A protein that breaks, swivels, and rejoins DNA strands. During DNA replication, topoisomerase helps to relieve strain in the double helix ahead of the replication fork.
- Eukaryotic chromatin that remains highly compacted during interphase and is generally not transcribed.
5 True/False questions
nucleoid → An enzyme that cuts DNA or RNA, either removing one or a few bases or hydrolyzing the DNA or RNA completely into its component nucleotides.
bacteriophage → One of two prokaryotic domains, the other being Archaea.
helicase → An enzyme that joins RNA nucleotides to make the primer using the parental DNA strand as a template.
bacteria → Member of the prokaryotic domain Bacteria.
primer → A short stretch of RNA with a free 3' end, bound by complementary base pairing to the template strand, that is elongated with DNA nucleotides during DNA replication.
