Question
Our yeast, S. pombe, is an ideal model because it is haploid. Why is this an advantage?
there is no second gene copy to mask the effects of a gene mutation
they have many genes in common with humans
the cells divide faster so we can complete our experiments more quickly
it's easier to mutate the genes we want because there are fewer of them
a.there is no second gene copy to mask the effects of a gene mutation
b.they have many genes in common with humans
c.the cells divide faster so we can complete our experiments more quickly
d.it's easier to mutate the genes we want because there are fewer of them
Explanation / Answer
We will go through all the option one by one then we will see the right option
Option b. S pombe has around 6000 genes where human have more than 20000 genes
Option c. S pombe generation time is 3-4 hours but S cerevisiae generation time is 80 to 100 mins
Option d. Since it has around 5000 genes and S cerevisiae has around 5500
Option a. S Pombe is haploid organism whereas S cerevisiae is diploid. S pombe is used as a model organism just because it is haploid not because of the other options given in the question
