Where does RNA editing occur in the cytoplasm of an animal cell? During protein synthesis, ___ occurs in the nucleus as a copy of DNA is made into mRNA, and ___ begins in the cytoplasm, when mRNA associates with a ribosome. How does splicing of pre-mRNA occur? What would happen if...
How does splicing of pre-mRNA occur? What is RNA splicing? Which strand of DNA is used to make mRNA? What mRNA codon starts the making of a protein? Where does the mRNA get transcribed? How do I transcribe DNA to mRNA and mRNA to protein?
Although several studies have investigated the transcriptional changes that occur during sexual development and attempted to identify genes that may be involved, the molecular basis of sexual conversion has been elusive. Recent work has identified an apicomplexan-specific transcription factor as a key regu...
Despite the significant effort made during recent years to comprehend the molecular mechanisms involved in HSC activation and de-activation, how exactly these processes occur and how they can be manipulated for therapeutic purposes is still under scrutiny. Multiple studies, both in vivo, using animal...
a A bacterial cell contains thousands of ribosomes which are made of RNA and protein. When viewed even by very high magnification, ribosomes show up as fine, spherical specks dispersed throughout the cytoplasm that often occur in chains (polysomes). 一个细菌细胞包含由RNA和蛋白质制成的数以万...
Pathogenic variants in many other genes, including protein components of the sarcomere (e.g.TNNT2, TPM1), Z-disk (e.g.TCAP, MYPN, NEXN), cytoskeleton (e.g.DES, VCL), desmosome (e.g.DSP), and RNA-binding proteins (e.g.RBM20), have been reported in DCM cohorts. Individually, the...
(RNP) complex needs time to enter the nucleus, find its target and cleave the DNA. Furthermore, if injecting Cas9 mRNA, translation to Cas9 protein must also occur, further delaying the editing process, thus resulting in a higher rate of mosaicism. It has been suggested that injection of ...
As more and more acid is accumulated, storage capacity is diminished, and the body’s ability to manage the accumulation falters, the body slowly begins to suffocate in its own acid waste. By this time cellular metabolism has been severely compromised, enzymatic reactions fail to occur, nutrient...
III. They must occur in the nucleus before the RNA moves into the c What is the mRNA codon sequence that must be first to start translation? a. AUG b. TAC c. UAA d. UAG e. UGA How does splicing of pre-mRNA occur? What three codes tell...
However, this remains a purely speculative model and it is not clear whether BCR re-expression by BCRlow cells can or does occur in vivo. It is equally plausible that receptor replacement is a relatively rapid but continuous process and that the seemingly non-crippled BCRlow cells observed ...
