Gene: sax-3
Question:
Test a different neuron to see how wide spread your function
is:
You just found that your protein is involved in neural
development in PHB neurons. To test if this is a wide-spread
effect, you can label other neurons in the animal using a
transgenic array, and introduce the transgenic array into your
mutant.
1. Explain the approach and why it would be useful?
2. Show Genetic Crosses You would do in C. elegans to introduce the
transgenic array into your mutant.
3. Explain the phenotype you would look for.
4. What are the limitations of this approach.

3. (2 points) In the nematode roundworm, Caenorhabditis elegans, the LIN-14 protein controls the timing of certain cell divisions during development. LIN-14 protein levels are normally high in early development but decrease in the later stages. In a lin-4 mutant, the level of LIN-14 protein stays high throughout development, changing the pattern of cell divisions in the animal and producing defects in the shape of the animal. The lin-4 gene encodes a microRNA that binds to a sequence in the...
Question 4 You have been asked by your supervisor to help with their study on a tumor suppressorgen in humans Shown below is the structure of a human tumor suppressorgee divided into 10 se designated A-L. The gene contains three exons, two intron, a promoter, and a site in for poly(A) addition Expn 1 Ex Promoter Iron Iron MIA a) What segment or segments of the gene will be represented in the newly transcribed RNA transcript! List in order, the...

part last part of question says: explain why this type of mutation
is your selected protein or protein complex would fix your initial
defect
3. (8 points) You observe a population are missing their DNA chromosome after di occurred to eliminate the function of an import packaging or localizing partitioning of the cell in two ve a population of dividing cells and discover that many of these cells some after division! You suspect that a mutation has mate the...
looking for question 3 a,b,c,d,e,f,g,h and i. Thank you
it's the same question with different situations.
3. Now let's use trial-and-error to see if we can figure out the inheritance pattern of this trait. For EVERY pedigree diagram below and on the following pages, label what you know about the genotype of each individual shown from the information provided in the pedigree and the assumption specified above each one. You MUST label ALL FOUR diagrams separately! Genotypes in these pedigrees...

5'-GCATGAGTCTGGTACGCTTTTAAAGC-3' 3-CATGCG-5' IIIII 3. (a) in the sequence above, what enzyme would you need to extend the short stretch of nucleotides shown on the bottom strand? (b) Write the sequence of the newly synthesized fragment and label its S' and 3' end. (c) The covalent bond between these adjacent nucleotides is what type of chemical bond? After using a chemical mutagen to generate mutations in a DNA sequence, scientists noted a mutation from C to T at the...
