4. The non-template strand sequence of a eukaryotic gene is given below. The promoter sequence is underlined. The +1 nucleotide is shown in boldface and red. a. Write the sequence of the mRNA that would be produced by this gene. You may assume that the gene ends at the end of the sequence shown, so you do not need to look for transcription termination signals. You may also assume that it has no introns 5' GCGGTATAACAGGACAGGCTGCATGAGAAGATTCCATCTTCCAGATCACTGTCCTTCTAGCCATGGAAAATGA CGAATTGTGACTGCCCCTGC3' mRNA (make sure...
Given the template DNA sequence below: 3'-CCACCTTCTATACTTCGCGGAATGCCGGTCCATGTAGGTTCACATTAGCGT-5' 6. An error occurred in DNA replication, A was incorporated in the place of T (indicated in yellow color in the aforementioned sequence) from the gene. Write the corresponding DNA template strand and transcribe the mutated mRNA strand, then determine the amino acid sequence of the mutant protein. If a stop codon is not present, create one by adding sequences to the gene and mRNA.
Sequence motifs are the sequences of nucleotides that indicate what types of function or absence of function may be encoded in a particular region of the genome. Which statement is true regarding sequence motifs? Sequence motifs are found in DNA and in corresponding RNA produced by transcription. Sequence motifs are telltale sequences of nucleotides that indicate possible function. An open reading frame (ORF) is a type of sequence motif. Sequence motifs help identify sequences that encode protein-coding genes. All of...

Suppose you were asked to design a program to search a protein sequence database for sequences that may form a-helices and β-strands on the surface of a protein (so one side of the helix or strand is surface-exposed, and one side is buried in the protein), a. What kinds of patterns in the sequence would you search for? b. Give 15 residue-long examples of a-helix and p-strand that could be found in this position in the native structure of a...
1) The 5'-end of an mRNA has the sequence: ...GUCCCAUUGAUGCAUGAAUCAUAUGGCAGAGCCCGCUGG... What is the nucleotide sequence of the DNA template strand from which it was transcribed? 2) If this mRNA is translated beginning with the first AUG codon in its sequence, what is the N-terminal amino acid sequence of the protein that it encodes?
