Question
Chapter 16, Problem 14PIAT
Summary Introduction
To review:
Whether the mRNA (messenger ribonucleic acid) produced by the zebra fish, puffer fish, mice, and humans have same mRNA base-pair sequence or not.
Introduction:
The eukaryotic mRNA is defined as the molecule that determines the amino acid sequence of the protein. The structure of the eukaryotic mRNA includes the five-prime cap (5′ cap), 5’ UTR (untranslated region), coding sequence, 3’ UTR, and the poly (A) (poly-adenine monophosphates) tail.

Students have asked these similar questions
Structural analysis of bacterial release factor 1 (RF-1) and release factor 2 (RF-2) reveals that these proteins are similar in size and shape to a tRNA molecule. This similarity has sometimes been called molecular mimicry. Why might RF-1 and RF-2 have evolved to mimic tRNAs?
To construct an “interactome” like the one shown in Figure 9-21, scientists identify all of the protein interactions in a particular tissue or cell type. Comparison of interactomes from human muscle versus human brain tissue reveals very different patterns. If you were the scientist involved in this study, how would you explain these results?
Why do humans have such a large number of nucleotides (3.2 billion base pairs) compared to the number of nucleotides in the Japanese pufferfish (with only 400 million base pairs)?
the difference is due primarily to a relative abundance of intron nucleotides in humans
the difference is due primarily to a relative abundance of euchromatin sequences in humans
the difference is due primarily to a relative abundance of intron sequences in humans
the difference is due primarily to a relative abundance of protein-coding genes in humans
the difference is due primarily to a relative abundance of exon sequences in humans

- Using a computer algorithm that searches for sequence similarities in other organisms, you discover that hexose kinase is a highly conserved gene that is expressed by many species, both prokaryotic and eukaryotic. The most closely related prokaryotic homolog of hexose kinase has a protein sequence in which 90% of the amino acids are identical to those of the human version of the gene. To learn more about their similarity at the DNA level, you obtain segments of the genomic DNA coding for the hexose kinase gene in both humans and this prokaryotic species. After combining both DNA samples, you heat them to denature the DNA strands and then allow them to cool and reanneal. Finally, you examine the DNA hybrids you obtain under the electron microscope. Your analysis reveals that there are three different DNA hybrids in this sample, these can be seen below. You reason that one must belong to the prokaryotic species, one to the humans and the third arose when one strand from each species base…arrow_forwardStructural analysis of bacterial release factor 1 (RF-1) and release factor-2 (RF-2) reveals that these proteins are similar in size and shape to a tRNA molecule.

A point mutation is the result of a single base substitution in the DNA encoding a gene. The sickle cell mutation results in substitution of Val for Glu at position 6 in the B-globin protein. (a) Using the information in Figure 5.18 explain how a point muta- tion could change a codon for Glu to a codon for Val. (b) Do you expect the pI for the sickle cell B-globin to be higher or lower than the pl for wild-type B-globin? Explain.arrow_forward
- A group of researchers isolate 'Protein X' from the wall of a human stomach with the intent of learning how to synthesize stomach tissue in the lab. Subsequently, they determine the exact sequence of amino acids of the protein in its unfolded state, and create a functional mRNA template to translate Protein X in vitro. They manage to translate an exact copy of the polypeptide chain in the lab, but then realize that it takes several days for the protein to fold into its final tertiary structure. In vivo, they observe that several thousand copies of Protein X are folded from polypeptide chains every minute. What is NOT a plausible explanation for this difference in folding times? The in vitro study lacks a key enzyme The temperature in vitro is too low The in vitro study lacks a key tRNA molecule The pH in vitro is too higharrow_forwardConsider the following tRNAs, where the numbered forms represent the amino acids associated with them, answer briefly: PICTURE Question 1: The numbering indicates the order in which these tRNAs are recruited to the A site of the ribosome.

Question 3: Researchers discover that a mutation is in the anticodon of the gene encoding the proline tRNA of an individual. The anticodon sequence is normally 3' GGA 5', but in this individual the anticodon sequence is 3' GGG 5'. It appears that this individual suffers no adverse consequences. How can this be?

They then removed the sulfur group from the cysteine, creating alanyl-tRNACys (charged tRNACys + alanine). When alanyl-tRNACys was added to a synthetic mRNA calling for cysteine, but not alanine, a polypeptide chain was synthesized containing alanine. What can you conclude from this experiment?arrow_forward
- In relation to central dogma of molecular biology answer the following questions: The length of a particular gene in human DNA, measured from the start site for transcription to the end of the protein-coding region, is 10,000 nucleotides, whereas the length of the mRNA produced from this gene is 4000 nucleotides.

- Some DNA nucleotides are located within the coding regions of genes, where they specify the amino acid sequence of a protein. Other nucleotides are found in regulatory elements, where they serve as binding sites for regulatory proteins, such as general transcription factors, transcriptional activators, and transcriptional repressors. It has long been assumed that sequences within coding regions and sequences within regulatory elements are independent, but recent research has determined that about 15% of human codons—dubbed duons—serve both to encode amino acids and as binding sites for regulatory proteins. How might the presence of duons affect which synonymous codons are used in the genetic code?arrow_forwardA certain membrane protein is found on the ER membrane with the N-terminus on the ER side of the membrane and the C-terminus on the cytosol side of the membrane.
