Answer:
Mutations:
When DNA changes then it is called mutations.In then others words when DNA is damaged or we can say that when it changed then it changes the genetic genes and this changes in genetic gene is called mutations.
The types of mutations
1.Non sense mutations
2. Missense mutations
It can affect the genetic order .This is called genetic disorder.
Answer: Here is the option.
A. The inducer combines with the repressor and causes the repressor to bind to DNA
B. The inducer combines with the repressor and causes the repressor to dissociate DNA
C. The inducer combines with the substrate and blocks induction
D. The inducer combines with the substrate and activates induction
E. The inducer does not combine with repressor but functions as a chaperone molecule for the enzyme-substrate complex
The correct option is C.
The inducer combines with the substrate and blocks induction
Explanation:
Enzymes inducers are drugs or enzymes that Induces or bring out the activity of enzymes been expressed.
This drug increases the metabolic activity of an enzyme either it binded to the enzymes or in a away cause an increase gene code of an enzyme to be expressed.
When an inducer is added to a medium containing an organism with metabolic pathway controller by a repressor it will combine with the repressor and block induction because an enzyme repressor regulate enzyme activity in a negative way by reducing it's synthesis rate.
Meiosis. Meiosis is termed as a specialized cell division which reduces chromosomes number by half and then creates for haploid cells. The process of meiosis occurs in multicellular eukaryotes and in sexually reproducing single-celled.
Answer:
Vacuoles are larger in plant cells than in animal cells
Answer:
Adolescence is known as the years between the start of puberty and the beginning of adulthood. Starting roughly between ages 12 and 13 and ending by age 20, at which time the child got a job or went to work on the family farm, married, and started his or her own family. Today, children mature more slowly, move away from home at later ages, and maintain ties with their parents longer. For instance, children may go away to university but still receive financial support from parents, and they may come home on weekends or even to live for extended time periods. Thus the period between puberty and adulthood may well last into the late 20s, merging into adulthood itself. In fact, it is appropriate now to consider the period of adolescence and that of emerging adulthood (the ages between 18 and the middle or late 20s) together.
