How and why does the RNA self replicate? Why is DNA better than RNA as genetic material? Explain. How does RNA polymerase generate RNA without a primer? How do RNA retroviruses enter lysogeny? Why does RNA transcription occur? How is RNA converted into cDNA?
Describe mRNA splicing. What is mRNA? (messenger RNA) Distinguish DNA from RNA, what is the same, what is different? Importance in function? What are the differences between RNA polymerase and primase? How does the transcription of DNA to RNA work? Describe the structure of RNA. RNA types:...
Several ribosomes can attach to a molecule of mRNA one after another and begin making proteins. So, several proteins can be made from one mRNA. In fact, inE. colibacteria, translation of the mRNA begins even before transcription is finished. Mitochondrial DNA Mitochondria resemble an early form...
A protein coding gene thus emerged does not inherit the DNA sequence features necessary for gene expression (transcription and translation), from an ancestral protein coding gene. It must therefore acquire them through random mutations. The most basic requirement for translation is an open reading ...
(New England Biolabs) was added for 1 h to allow for reverse transcription to occur. Finally, 6 nmof 5′-32P-labeled right flanking pssDNA (SM83/SM84) was added and annealing was performed for 30 min. In Fig.5b, c, reactions were terminated by the addition of stop buffer (...

These transcription factors are postembryonic determinants of the ground tissue stem cells and their lineage. Upon further activation by the positional signal SHORT-ROOT (a mobile transcription factor), they direct asymmetric cell divisions and patterning of cell types. The BIRDs and SCARECROW with ...
How can one mRNA sequence from one area of DNA code for more than one protein? A gene contains the sequence, ggctaac. What is the sequence of the mrna transcribed from this strand? A) What is the proces...
How do I transcribe DNA to mRNA and mRNA to protein? What is transcription? Describe the process of transcription. Where does it occur? What enzyme(s) are involved? What is the product(s)? Explain the roles of transcription and translation in converting ...
