Reverse transcriptase, also called RNA-directed DNA polymerase, an enzyme encoded from the genetic material of retroviruses that catalyzes the transcription of retrovirus RNA (ribonucleic acid) into DNA (deoxyribonucleic acid). This catalyzed transcription is the reverse process of normal cellular transcrip...
Transcription is the process of synthesising an mRNA molecule based on a gene sequence on DNA. It is carried out by the RNA polymerase enzyme.Answer and Explanation: The constituents, or monomers, of DNA and RNA are nucleotides. They are made of 3 things: a phosphate residue a pentose su...
What is the role of DNA and RNA in mitosis? How do transcription and translation result in the expression of genes? Explain the difference between DNA replication and RNA transcription. Explain the role of tRNA in protein synthesis. Include a description of how it interacts with mRNA and the ...
also, designate the protein that is encoded by this message.tRNA: UAC UCU CGA GCGmRNADNAProteinhow many hydrogen bonds would be present in the DNA segment?10.in which process, transcription or translation, do each of the following function:RNA polymerase, ribosomes, nucleotides, tRNA, pre-...
RNA-seq, a comprehensive sequencing technique, revolutionizes our understanding of gene expression and transcription regulation within cells. This powerful approach involves a systematic process:Firstly, total RNA, including both mRNA and non-coding RNA, is extracted from cells or tissue ...
Just as with DNA, it is possible to sequence RNA. Transcriptome sequencing can be done to learn more about the actions of a cell and the host organism's DNA, and to identify the places where the expression of genetic information goes wrong. When a liver cell becomes malignant, for example...
Furthermore, mRNAs may localize to specific areas in the cell, and the spatial organization and dynamics of the chromosome have been shown to be important for transcription. Epigenetic modifications of DNA also affect transcription, and RNA processing affects translation. Therefore, transcription in ...
In this lesson on RNA, see the ribonucleotide definition, learn what RNA does, why RNA is important, what RNA is made of, and see RNA types and...
The protein NusA (Mr 54,430) binds to the elongating RNA polymerase, competitively with the σ subunit. D. Once transcription is complete, NusA dissociates from the enzyme, the RNA polymerase dissociates from the DNA, and a σ factor (σ 70 or another) can again bind to the enzyme to...
Transcription is a source of genome instability that stimulates mutation and recombination. Part of the damage produced by transcription is mediated by R-loops, non-B DNA structures that normally form by the re-annealing of the nascent RNA with the template DNA outside the catalytic center of th...
