In many organisms, 3' maturation of tRNAs is catalyzed by the endoribonuclease, RNase BN/RNase Z, which cleaves after the discriminator nucleotide to generate a substrate for addition of the universal CCA sequence. However, tRNAs or tRNA precursors that already contain a CCA sequence are not ...
Shown below is a codon in an mRNA. What is the correct sequence of the tRNA anticodon that recognizes this codon?\\mRNA codon: 5' - CAG - 3'\\ How does the sequence of nucleotides in DNA correspond to a sequence of amino acids in a polypeptide? An mRNA has the sequence 5'-...
How and why are proteins added to sugars? Describe proteins. 5'-CUU-UUC-CCU-UGG-AUG-3' a. Write the polypeptide (protein) sequence coded for by this section of mRNA. b. Write the nucleotide sequence of the DNA strand from which the given mRNA strand was directly synthesized. Define codo...
A hairpin, with an intramolecular loop of eight nucleotides, was within the operator and the loop became the subject of Craig's deep mutagenesis, in which every possible loop sequence (all 48 of them) was selected for binding to the polymerase. Two sequences emerged (the wild-type and the...
Each article a research professor at a public university writes is at least somewhat unique (hopefully), but the core components (microeconomic concepts, logit regression analysis, action research, etc.) are not. Modular assembly works best for less linear, more iterative production processes. The...
a) What happens to the mRNA after translation is complete? b) What is a transfer RNA (tRNA), and what does it do? c) What is produced and then used by the cell at the end of translation? What would happen if the ...
In the space below, write the nucleotide sequence Explain why simultaneous transcription and translation can happen in bacteria but not in eukaryotes. Which is correct about transcription? a) For transcription to actually occur, the RNA polymerase must bind transcription...
The relationship between the sequence of nucleotides on mRNA and the sequence of amino acids in the polypeptide (protein chain) is called a genetic code. There are four kinds of nucleotides - adanine (A), guanine (G), cytosine (C), uracil (U), and thymine (T). Among these, ...
Draw the free-body diagram for the system shown and use it to write the differential equations of motion. Solve for the natural frequencies of the system, in terms of k and m, and determine the corres Consider the diagram below. What is the DC gain of the system? Derive a plot ...
Describe the primary structure of protein. What makes one protein different from another protein of the same size? What is the basis of the unique conformation of a protein? What role is played by tRNA in cells? a. telling the cell ...
