Explain, in general terms, the role of RNA in gene expression. Why is RNA useful to a cell? What is the benefit of using RNA instead of just directly producing protein from the instructions in DNA? How does the transcription of DNA to RNA work?
Genetic expression in Biology refers to the physical manifestation of the information encoded in DNA (the message). Genetic expression involves the generation of a molecule of a different nature than the DNA that encodes it. For example, as the central dogma st...
Nucleus, transcription, RNA, nucleus, cytoplasm, translation DNA (___ ___) goes through transcription with the help of ___ ___ and mRNA(___ ___) goes through translation with the help of ___ to create a ___ Information storage, RNA Polymerase, information carrier, ribosome, protein...
So, scientists had theorized about the informational role of DNA for a long time, but nobody knew how this information was encoded and transmitted. Many scientists guessed that the structure of the molecule was important to this process. In 1953, James D. Watson and Francis Crick discovered th...
How do transcription enzymes know the sequence of DNA that is to be translated into a required protein? How does RNA polymerase choose which strand to start to use as a template? a. RNA can only transcribe from the strand with the most major units. b. Certain seque...
The gene KCNN4 which encodes the Ca2+ activated K + channel is identified in nearly about 30% of gliomas according to the REMBRANDT database and is associated with an unfavorable outcome [31]. The migrating ability of glial cells is facilitated by cellular volume changes that modify the ...
TLR7is the most well-studied X-linked gene associated with lupus. This gene encodes a receptor expressed in the intracellular compartments of immune cells, such as B lymphocytes, dendritic cells, and macrophages. TLR7 recognizes viral motifs in single-stranded RNA (ssRNA), particularly guanosine- ...
which occurs during DNA replication and transcription. One way to visualize supercoiling is to think about what happens when you twist a rubber band and then hold onto one end of it while trying to open it in the middle — the original coils will twist on top of each other to form a ...
synonymous than nonsynonymous substitutions, specifically among homologous coding sequences. The pattern of nonsynonymous to synonymous differences among homologous regions compared in a phylogenetic group can be used to predict the likelihood that a genomic locus encodes a translated open reading frame (...
DNA transcription occurs in the nucleus, where an RNA polymerase complex forms in order to create mRNA. A gene must first be exposed through certain...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
