Aniridia is a human condition in which the eye has no iris. the protein encoded by the gene responsible for aniridia is very nearly identical to the protein product of the fly eyeless protein. what experiment could provide evidence that the two genes are functionally equivalent? a. introduce the aniridia mutation into drosophila embryos to look for iris formation. b. sequence the eyeless and aniridia dna sequence and regulators. c. use the eyeless mrna as a probe in other invertebrate and non-mammalian species. d. introduce the mouse aniridia wild-type sequence into the fly to see whether flys eyes develop. e. introduce the mouse wild-type sequence into the fly egg to see whether mouse eyes develop.

How do you transfer mrna into codons ? i'm so confused : (

Fan egg cell containing the (n+1) number of chromosomes combines with a sperm cell containing the (n) number of chromosomes, what is the result of this union? a) all future somatic cells of the organism will contain the (2n + 1) number of chromosomes. b) all future somatic cells of the organism will contain the (2n - 1) number of chromosomes. c) only certain somatic cells of the organism will contain the (2n + 1) number of chromosomes. d) all future somatic cells of the organism will contain the normal diploid number of chromosomes.

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
