Translating the unmutated MRNA that was obtained after splicing, the original protein sequence will be?

A protein has the following amino acid sequence: Met-Tyr-Asn-Val-Arg-Val-Tyr-Lys-Ala-Lys-Trp-Leu-Ile-His-Thr-Pro You wish to make a set of probes to screen a cDNA library for the sequence that encodes this protein. Your probes should be at least 18 nucleotides in length. a. Which amino acids in the protein should be used to construct the probes so that the least degeneracy results? b. How many different probes must be synthesized to be certain that you will find the cDNA sequence that specifies the protein?

what is the difference between leader mRNA and attenuator sequence? Please explain the function of attenuator sequence in attentuation

What is the net gain in the number of chemical bonds during splicing of an intron? Please explain your answer.

What polypeptide product would you expect from apoly-G mRNA that is 30 nucleotides long?

The abundance of three mRNA transcripts, transcripts A, B, and C, was measured by real-time PCR. The average CT values were 14.6, 20.2, and 10.5 for transcripts A, B, and C, respectively. Determine the relative order of abundance of the transcripts. Name one technique that could be used to confirm that the order of abundance at the mRNA transcript level is reflected at the protein level.

Shown below is a schematic drawing of a gene, with the transcription unit divided into numbered regions. The arrows (;) indicate transcription initiation sites, "D" indicates a splice donor site, "A" indicates a splice acceptor site, and "An" indicates a polyadenylation signal. Give all the possible fully processed mRNAs that could be produced from transcripts of this gene (you don't need to draw anything, just list the regions that would be included in each mRNA by number).

Consider the following DNA template:   5’-AAGAGGTTCCAATGCAGGCACTCACCAACTCTTAAATAAA-3’ 3’-TTCTCCAAGGTTACGTCCGTGAGTGGTTGAGAATTTATTT-5’   If the bottom DNA  strand is used as template to transcribe mRNA, predict the amino acid sequence that would result from the process of translation.   Met-Ala-Leu-Thr-Gln-Glu-Gly Met-Gly-Ser-Leu-Asn-Ser-Gln Met-Thr-Asn-Ser-Leu-Ala-Gln Met-Gln-Ala-Leu-Thr-Asn-Ser Met-Glu-Ala-His-Trp-Ser-Tyr

Suppose you have a 1-kb segment of cloned DNA that is suspected to contain a eukaryotic promoter including a TATA box, a CAT box, and an upstream GC-rich sequence. The clone also contains a gene whose transcript is readily detectable. Your laboratory supervisor asks you to outline an experiment. (1) determine if eukaryotic transcription factors (TF) bind to the fragment and, if so, (2) identify where on the fragment the transcription factors bind. All necessary reagents, equipment, and experimental know-how are available in the laboratory. Complete the outline of an experiment, which determines if eukaryotic transcription factors (TF) bind to the fragment. Assume all necessary reagents, equipment, and experimental how are available in the laboratory. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. For the band shift assay, two samples of the DNA fragment are analyzed by agarose gel electrophoresis: one sample is…

in the human gene for the beta chain of hemoglobin, the first 30 nucleotides in the amino acid coding region is represented by the sequence 3'TACCACGTGGACTGAGGACTCCTCTTCAGA-5'. What is the sequence of the partner strand? If the DNA duplex for the beta chain of hemoglobin above were transcribed from left to right, deduce the base sequence of the RNA in this coding region.
