WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA … WebDNA is read-only memory, archived safely inside cells. Genetic information is stored in an orderly manner in strands of DNA. DNA is composed of a long linear strand of millions of nucleotides, and is most often found paired with a partner strand. These strands wrap around one another in the familiar double helix, as shown here.

WebApr 9, 2024 · Single-strand binding proteins coat the DNA around the replication fork to prevent rewinding of the DNA. Topoisomerase binds at the region ahead of the replication fork to prevent supercoiling. Primase synthesizes RNA primers complementary to the DNA strand. DNA polymerase starts adding nucleotides to the 3'-OH end of the primer. WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a …
