Question

In genetic analysis, the test is used to determine whether two recessive mutations that cause similar phenotype are allowed of the same gene. DNA strands are said to be because the phosphate linkages in the backbones run in opposite directions. An arrangement of metaphase chromosomes according to their and centromere placement is called a An enzyme called can produce a complementary DNA strand from an RNA template

Answer 1

q-5) Many genetic research programs are undertaken to attempt to understand the genes that contribute to one particular biological process. Such an analysis begins with a collection of related mutant phenotypes centered on that particular process. For example, if a geneticist were interested in the genes determining locomotion in a nematode worm, the genetic dissection would begin by isolating a set of different mutants with defective locomotion. An important task is to determine how many different genes are represented by the mutations that determine the related phenotypes, because this number defines the set of genes that affect the process under study. Hence it is necessary to have a test to find out if the mutations are alleles of one gene or of different genes. The allelism test having the widest application is the complementation test, which is illustrated in the following example.
