Question 1: While examining a gene related to calcium ion channels in humans(CACNA1S) you discover a nearby region that likely codes for an miRNA associatedwith CACNA1S. What evidence would lead you to this conclusion? Stated anotherway, what would the discovered DNA region look like to convince you that youhad found an miRNA region associated with CACNA1S? (Hint: be mindful of the 3'-5' or 5'-3' direction in your answer)A. The template strand coding for the miRNA contains regions identical to thetemplate strand of the CACNA1s gene.B. The template strand coding for the miRNA contains regions identical to thecoding strand of the CACNA1s gene.C. The template strand coding for the miRNA contains regions antiparallel tothe template strand of the CACNA1s gene.D. The template strand coding for the miRNA contains regions antiparallel tothe coding strand of the CACNA1s gene.

D IS THE CORRECT ANSWER. AND EXPLANATION IS GIVEN BELOW .Explanation:

Question 36
Please help me with the question below - it is linked to developmental biology/genomics. Please be as brief and concise as possible, while being sure to completely answer the question.
About how many GTps does it take to synthesize a protein 100 amino acids long?
This problem investigates issues encountered in sequencing the inserts in cDNA libraries.a. If you sequenced many clones individually, wouldn’tyou spend many of your resources inefficiently sequencing cDNAs for the same type of mRNA molecule over and over again? Explain. Does thisapparently inefficient process provide any useful information beyond the sequences of individual mRNAs?b. Suppose that you identified a clone with a cDNA insert that was 4 kb long. You could determine the entire sequence of the clone by shearing the DNA intosmall random fragments, cloning these fragments intoa vector to make a mini-shotgun library, and then sequencing hundreds of these clones to allow the computer to assemble the full sequence of the 4 kb–longinsert. However, this procedure would be inefficient.An alternative that requires many fewer sequencing reactions is called primer walking. This techniqueinvolves the synthesis of additional oligonucleotideprimers corresponding to cDNA sequences you…
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…
