- Introns in protein-coding genes of some eukaryotes are rarely shorter than 65 nucleotides long. What might be a rationale for this limitation?arrow_forwardA normal hemoglobin protein has a glutamic acid at position 6; in sickle-cell hemoglobin, this glutamic acid has been replaced by a valine. List all the possible mRNA codons that could be present for each type of hemoglobin. Can a single base change result in a change from Glu to Val in hemoglobin?arrow_forwardDuchenne muscular dystrophy is caused by a mutation in a gene that comprises 2.5 million base pairs and specifies a protein called dystrophin. However, less than 1% of the gene actually encodes the amino acids in the dystrophin protein. On the basis of what you now know about gene structure and RNA processing in eukaryotic cells, provide a possible explanation for the large size of the dystrophin gene.arrow_forward

Using the following list of codons describe, using diagrams etc., how information stored in the DNA is translated into a peptide. Be sure to discuss all steps. In other words, use a diagram and give me sequences, transcription and translation steps. Show the sequences of the sense and the other DNA strand, the mRNA and the tRNA’s.

- Microbiologists describe the processes of transcription and translation as “coupled” in bacteria. This term indicates that bacterial mRNA can be undergoing transcription at the same moment it is also undergoing translation. How is coupling possible in bacteria? Is coupling of transcription and translation possible in single-celled eukaryotes, such as yeast? Why or why not?arrow_forwardWhat is meant by the term histone code? With regard to gene regulation, what is the proposed role of the histone code?arrow_forwardThe Dscam locus in Drosophila melanogaster has 24 exons. Four of these exons are able to undergo alternative splicing. Exon 4 has 12 possible splice variants, exon 6 has 48 variants, exon 9 has 33 variants, and exon 17 has 2 variants. If all splicing combinations are possible, how many different Dscam protein sequences could be encoded by a single allele at this locus?arrow_forward
- What are the two important sequence elements in the prokaryotic gene promoter? How does the RNA polymerase find the promoter?arrow_forwardWhat is the meaning of the term consensus sequence? Give an example. Describe the locations of consensus sequences within bacterial promoters. What are their functions?arrow_forwardSome 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_forward
