WebMay 14, 2024 · Some 50 different protein transcription factors bind to promoter sites, usually on the 5′ side of the gene to be transcribed. An enzyme, an RNA polymerase, binds to the complex of transcription factors. Working together, they open the DNA double helix. The RNA polymerase proceeds to read one strand moving in it's 3'→ 5' direction. WebTranscription is the first step of gene expression. During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting … mehr theater saalplan

WebJan 19, 2024 · An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell. WebColor the nucleotides using the same colors as you colored them in the double helix. The two sides of the DNA ladder are held together loosely by hydrogen bonds. The DNA can actually "unzip" when it needs to replicate - or make a copy of itself. DNA needs to copy itself when a cell divides, so that the new cells each contain a copy of the DNA.
