Answer:
Adaptive laboratory evolution selects many genome-wide mutations that contribute to the fitness of actively growing cultures, whereas directed evolution typically targets a specific gene for mutagenesis and then screens the resulting variants for a phenotype of interest, often independent of fitness effects.
Explanation:
Answer:
Directed evolution is the laboratory process by which biological entities with desired traits are created through rounds of genetic diversification. It can also be created through library screening or selection and has become one of the most useful tools in basic biology. It's role includes improving the stabilities or biochemical functions of proteins by repeated rounds of mutation and selection.
More simply said, directed evolution is a mimic of the natural evolution cycle in a laboratory setting.
It has indirectly revealed that single amino acid mutations can enhance properties such as catalytic activity or stability and that adaptation can often occur through pathways consisting of beneficial mutations.

Kate started by reviewing the different organs. She knew that ovaries produce the eggs (oocytes) and that her uterus was where a fetus would develop.

a. Ampuls of uterine tube
b. Isthmus of the tube
c. Cervix
d. Funds of terus
e. Body of uterus
f. Infundibulum of uten tube
Answer:
Refer below path of oocyte from Ovary to Vagina. Once oocyte is released by ovary, it is carried by uterine tubes to uterus either as unfertilized or fertilized ovum depending on presence or absence of sperm
path of oocyte from Ovary to Vagina. Once oocyte is released by ovary, it is carried by uterine tubes to uterus either as unfertilized or fertilized ovum depending on presence or absence of sperm.
Oocytes are developing eggs (an immature ovum). Within a follicle, oocytes grow until they are fully developed. The outer layer of the ovaries contains these follicles. Many follicles start to form during each reproductive cycle.
Normally, only one oocyte will grow into an egg and leave its follicle per cycle. Ovulation is the term for this action.
All of a woman's oocytes are present when she is born. As aging, this amount naturally declines. The quality and genetic stability of the oocytes are also compromised by aging.
