The first diagram below shows the levels of mRNA from two different genes (bicoid and caudal) at different positions along the anterior-posterior axis of a Drosophila egg immediately before fertilization.
1. The diagram illustrates the lac operon. The top picture shows the operon in the absence of lactose and the bottom picture shows the operon in the presence of lactose. What is the green shape, labeled “2”? a. Repressor b. Promoter c. RNA polymerase d. Operator 2. What type of operon does this portray? a. Repressible b. Inducible c. Co ...
DNA replication is initiated at promoter sequences in the DNA. RNA polymerase requires primers to initiate RNA synthesis. Okazaki fragments are the short fragments of DNA that are produced on the leading strand at the DNA replication fork.
Exam #3 will cover from gene expression to antimicrobial chemotherapy. This includes the Central Dogma of Gene Transfer in prokaryotes (replication, transcription and translation), eukaryotic gene expression, regulation of gene expression (the lac operon), bacterial genetics and antibiotics.
The process of copying a gene's DNA sequence into a sequence of RNA is called: A) replication. B) transcription. C) translation. D) PCR.
22 sie 2024 · From the iconic double helix model of DNA to the versatile roles of RNA in protein synthesis and gene regulation, get ready to test your knowledge on nucleotide sequences, base pairing rules, replication, transcription, and translation processes.
