Does RNA polymerase unwind DNA? Does virus transduction effect ribosomal RNA? Why can ribosomal RNA sequence not be used to group viruses? Does messenger RNA have uracil? Does an RNA virus go straight to the host DNA? Does messenger RNA enter the nucleus? Can ribosomes bind to double-strande...
Which of the following nitrogenous bases is only found in RNA but NOT in DNA? A. Thymine B. Guanine C. Uracil D. Adenine What is the name of the proteins that diffuse DNA wrap around? Match each of the following with either DNA or mRNA: 1. Forms a do...
How can antisense RNA be used to increase the translational efficiency of gene expression? How does mutation in telomerase impact DNA replication in dyskeratosis congenita? Describe genetic code. In an operon that is under negative inducible control, what would be the effect on gene expression if ...
RNA Transcription To build an RNA molecule, the area around a DNA gene must first relax and the two strands must temporarily separate. The separation allows an enzyme complex containing RNA polymerase to fit into a space and attach to the gene's starting area, or promoter, on one of the t...
There aretwo typesof ncRNAs, housekeeping ncRNAs (tRNA and rRNA) and regulatory ncRNAs, which are further classified according to their size. Long ncRNAs (lncRNA) have at least 200 nucleotides, while small ncRNAs have fewer than 200 nucleotides. ...
Avery and his colleagues found that the extract minus RNA or minus protein was positive in this assay; in contrast, the extract minus DNA was negative. These results provided evidence that DNA from the virulent S. pneumoniae strain was the transforming molecule and, importantly, the link to ...
Structure of a natural guanine-responsive riboswitch complexed with the metabolite hypoxanthine Riboswitches are genetic regulatory elements found in the 5' untranslated region of messenger RNA that act in the absence of protein cofactors. They are br......
What Is The Structure Of DNA? This manual is written in multiple combinations, but limited to just4 letters: A, T, G and C. Each letter denotes a nitrogenous base: A for adenine, T for thymine, G for guanine and C for cytosine. Every living being has a huge supply of these 4 base...
As DNA is replicated, which DNA base pair will bond to cytosine? adenine thymine cytosine guanine? Do prokaryotes have single-stranded DNA? What does DNA ligase do? Does DNA supercoil occur during replication? When is helicase used in transcription?
Why do all cells have the same DNA but different functions? Why is there no thymine in RNA? Why the nitrogenous bases of DNA are approximately perpendicular to the axis of the molecule? Why does DNA damage lead to autoimmunity? What makes the rungs of the DNA ladder?
