Chapter 21: Problem 13

In general, if we know the genomic DNA sequence of a gene we can reliably predict the nucleotide sequence of the RNA encoded by that gene. Is this statement also true for tRNAs in prokaryotes? What about tRNAs in eukaryotes?

Short Answer

Expert verified
The statement about predicting RNA from the DNA sequence is generally true for tRNAs in prokaryotes. It may not be true for tRNAs in eukaryotes due to additional RNA processing steps.

Step by step solution

01

Understanding DNA to RNA process

In general, when a gene is expressed, the DNA sequence is transcribed to produce RNA in a process controlled by the enzyme RNA polymerase. The base pairing rules apply here as Adenine (A) pairs with Uracil (U) and Guanine (G) pairs with Cytosine (C). If the genomic DNA sequence is known, this can help predict the RNA sequence produced by that gene.
02

Analysis of tRNA in Prokaryotes

In Prokaryotes, the statements hold true as transcription process here is straightforward. The DNA sequence is directly transcribed into RNA and further processes like editing or modifications are minimal in prokaryotes. Therefore, the RNA sequence can be reliably predicted by knowing the gene's DNA sequence.
03

Analysis of tRNA in Eukaryotes

In Eukaryotes, this statement would not always hold true. Evolved organisms like Eukaryotes undergo RNA processing steps like splicing, capping and addition of poly-A tail which change the sequence of RNA after it's transcribed from DNA. This means, without additional information on the processing, knowing the DNA sequence of the gene may not enable reliable prediction of the resulting RNA sequence.

Most popular questions from this chapter

Assume that, in a rare instance, a typical eukaryotic triose phosphate isomerase gene contains the correct sequences to permit accurate transcription in a prokaryotic cell. Would the resulting RNA be properly translated to yield the intact enzyme?

In the promoter of the \(E\). coli lac operon the \(-10\) region has the sequence: \(5^{\prime}\)-TATGTT-3'. A mutation named UV5 changes this sequence to: \(5^{\prime}\)-TATAAT-3' (see Figure 21.6). Transcription from the lac UV5 promoter is no longer dependent on the CRP-cAMP complex. Why?

CRP-cAMP represses transcription of the \(c r p\) gene. Predict the location of the CRP-cAMP binding site relative to the promoter of the crp gene.

Why are mutations within an intron of a protein-coding gene sometimes detrimental?

Mature mRNA from eukaryotic cells is often purified from other components in the cell with the use of columns containing oligo (dT) cellulose. These columns contain short segments of single-stranded deoxyribose thymidylate residues, oligo(dT), attached to a cellulose matrix. Explain the rationale for use of these columns to purify mature mRNA from a mixture of components.
