Describe DNA denaturation, renaturation (annealing), and how base composition affects DNA stability. What are the three main functions of the RNA molecule types? (Choose three best of five) a. Transcribe DNA to RNA b. Provide site for translation to protein c. Proofread the protein molecules ...
Chinese ride hailing company Didi Chuxing has announced the launch of bilingual functions on its app in Beijing, Shanghai and Guangzhou to serve foreigners as part of the company's globalization strategy. Belt and Road initiative brings Chinese firm and Malaysian firm together Beyond government-owned...
PCR: Steps Involved in Polymerase Chain Reaction from Chapter 54 / Lesson 12 477K Polymerase chain reaction (PCR) is a laboratory procedure that can create replicas of DNA. Explore the three steps of this revolutionary process: denaturation, annealing, and extension. Related to this Que...
Embryonic stem cells (ESCs) can be maintained in the naïve state through inhibition of Mek1/2 and Gsk3 (2i). A relevant effect of 2i is the inhibition of Cdk8/19, which are negative regulators of the Mediator complex, responsible for the activity of enhancers. Inhibition of Cdk8/19...
One of the most central questions about the repair of a double-strand DNA break (DSB) concerns how the two free DNA ends are brought together — a step called synapsis. Using single-molecule FRET (smFRET), we show here that both Ku plus XRCC4:DNA ligase IV are necessary and sufficient...
Smooth ER is heterogeneous and performs different functions in different locations. Some smooth ER is continuous with rough ER and is believed to be a site where the proteins that jut out from the membrane are carefully folded, giving them their three-dimensional structure. Other types of smooth...
Main Apoptosis is a major form of programmed cell death.1 The core apoptotic machinery is evolutionary conserved with caspases as the fundamental components.1, 2, 3 Caspases are specific cysteine proteases that are produced as inactive zymogens composed of an N-terminal pro-domain, a large subuni...
Both functions of the Spn/Nlg2 module were directly antagonized by Syd-1/Nlg1. Nlg1 and Nlg2 also had divergent effects on Nrx-1 in vivo motility. Concerning diffusible signals, Spn and Syd-1 antagonistically controlled the levels of Munc13-family protein Unc13B at nascent AZs, whose ...
-cloning DNA fragments -sequencing DNA fragments-Reconstructing the genome sequence from fragments why genome sequencing is important - understand gene regulation as whole-determine role of gene-identify new genes and their functions-identify causes of diseases-see the variation-- focus on variation ...
DNA-based data storage platforms traditionally encode information only in the nucleotide sequence of the molecule. Here we report on a two-dimensional molecular data storage system that records information in both the sequence and the backbone structure
