Brainbow is a genetic approach to fate mapping developed to label cells with a seeming rainbow of possible colors, which can be used to identify each individual cell in a tissue or even a whole embryo. Give the mechanics behind this technique. What are its applications to the field of Biology in general, and to Developmental Biology in particular?

Another way to study the role of proteins (e.g., transcription factors) that function in development is to microinject the mRNA that encodes a protein, or the purified protein itself, into an oocyte or embryo, and then determine how this affects the subsequent development of the embryo, larva, and adult. For example, if Bicoid protein is injected into the posterior region of an oocyte, the resulting embryo will develop into a larva that has anterior structures at both ends. Based on your understanding of the function of each developmental gene, what would be the predicted phenotype if the following proteins or mRNAs were injected into normal oocytes? A. Nanos mRNA injected into the anterior end of an oocyte B. Antp protein injected into the posterior end of an embryo C. Toll mRNA injected into the dorsal side of an early embryo
What genetic model of an organism is the most ideal? And why is it an ideal model in genetics?
To understand the genetic basis of locomotion in the diploid nematode Caenorhabditis elegans, recessive mutations were obtained, all making the worm “wiggle” ineffectually instead of moving with its usual smooth gliding motion. These mutations presumably affect the nervous or muscle systems. Twelve homozygous mutants were intercrossed, and the F1 hybrids were examined to see if they wiggled. The results were as follows, where a plus sign means that the F1 hybrid was wild type (gliding) and “w” means that the hybrid wiggled.a. Explain what this experiment was designed to test. b. Use this reasoning to assign genotypes to all 12 mutants. c. Explain why the phenotype of the F1 hybrids between mutants 1 and 2 differed from that of the hybrids between mutants 1 and 5

Describe the main technique for amplifying a segment of DNA (like the one you suspect is involved in Lee’s cancer) from a complex mixture of genomic DNA. Remember that the entire human genome sequence is known. (Hint: This is a technique that is commonly used by laboratories that do genetic testing and various other applications of molecular biology.)
What is the role played by biophysical properties in mechanisms of morphogenesis?
A paper hypothesizes that white flowers are unable to produce anthocyanins (purple pigments) because they lack a functional “A” protein. However, it is also possible that an unknown gene is responsible for the lack of anthocyanins. Now that they have isolated DNA sequences of the “A” allele, design an experiment to use these DNA sequences to distinguish between these two hypotheses.
If you wanted to make a mouse model for any of the following human genetic conditions (a–d), indicate which of thefollowing types of mice (i–vi) would be useful to your studies. If more than one answer applies, state which type ofmouse would most successfully mimic the human disease:(i) transgenic mouse overexpressing a normal mouse protein; (ii) transgenic mouse expressing normal amounts of amutant human protein; (iii) transgenic mouse expressing adominant negative form of a protein; (iv) a knockout mouse;(v) a conditional knockout mouse; and (vi) a knockin mousein which the normal allele is replaced with a mutant allelethat is at least partially functional. In all cases, the transgeneor the gene that is knocked out or knocked in is a form of thegene responsible for the disease in question.a. Marfan syndrome (a dominant disease caused byhaploinsufficiency for the FBN1 gene);b. A dominantly inherited autoinflammatory diseasecaused by a hypermorphic missense mutation in thegene PLCG2;c.…

How could they be used to study melanin expression in nomal skin cells?

When the S.cerevisiae genome was sequenced and surveyed for possible genes, only about 40% of those genes had been previously identified in forward genetic screens. This left about 60% of predcited genes with no known function, leading some to dub the genes fun (function unknown) genes. a)As an approach to understanding the function of a certain fun gene, you wish to create a loss of function allele. How would you do this? b)You wish to know the physical location of the encoded protein product. How would you obtain such information?
