Answer:
In the S Phase
Explanation:
This is because chromosome duplication occurs in this which is similar or the same to DNA synthesis
Answer:
b. cis test
Explanation:
A test that is used to determine if the mutation associated with a given phenotype is due to mutations in two different genes or due to different alleles of the same gene is called a complementation test.
A complementation test is also called as a cis-trans test.
If the mutations in a complementation test are located on the same position then the genes are termed as being on the cis position otherwise on the trans-position.
A cis test, that is if the genes are located on the same position serves as a control for the complementation test.
Answer:
A) once, during interphase I
Explanation:
Although meiosis has two phases, the chromosome replicate only once during interphase I. The DNA material replicates and cell builds up enough energy stores to drive the process through. Other events that occur during interphase are formation of new organelles including centrioles.
