UGA is the start signal for a translation.
Digestive juice is the name for all juices secreted by the organs from the digestive system such as salivary glands, stomach, pancreas and liver. All of them contain enzymes that are responsible for food (macromolecule) break down. Digestive juice from the stomach contains enzyme protease (pepsinogen) which breaks down proteins and stomach acids which is involved in chemical breakdown of food materials. So, that is why the wheat grains are broken into tiny particles.
Question:
A---enzyme A------>B----enzyme B------>C
Refer to the metabolic pathway illustrated above. If A, B, and C are all required for growth, a strain that is mutant for the gene-encoding enzyme A would be able to grow on medium supplemented with _____.
A) nutrient A only
B) nutrient B only
C) nutrient C only
D) nutrients A and C
Answer:
B) nutrient B only
Explanation:
The mutant has a mutation in the gene that codes for the enzyme A. Therefore, this mutant would not be able to convert the substance A into B. Without the presence of substance B, the final product can not be formed. However, if the mutant is supplemented with the substrate "B", it can convert the B into the final product (substance C). Therefore, the mutant would be able to grow in the medium to which the already prepared substance B has been added.
Explanation:
Recessive alleles lack the power to express the phenotypic traits of an organism. In order for the specific trait to be expressed, 2 copies of the recessive allele or homogenous recessive genotype is needed in the organism.
