Answer:
The sister chromatids are identical to one another and are attached to each other by proteins called cohesins. They are formed.
Explanation:
I’m definitely gonna say the first choice. The others don’t make much sense
Fertilization of the egg cell by the sperm usually takes place in the fallopian tube. The fertilized egg then travels to the uterus and implants in the endometrium.
<h3>What are fallopian tubes?</h3>
- Fallopian tubes are also called oviducts or uterine tubes. It is the passage through which the egg enters the uterine cavity from the ovary.
- Fallopian tubes are part of the reproductive tract. They have a smooth muscle wall, an inner mucous membrane, and an outer layer of loose supporting tissue (serosa).
<h3>Why does fertilization take place in the fallopian tubes?</h3>
The fallopian tube (oviduct) regulates fertilization through sperm induction and sperm hyperactivity. Sperm induction is achieved by rheotaxis, thermotaxis, and chemotaxis. Rheotaxis is caused by tubal fluid that creates a current flow from the tubal ampulla to the tubal isthmus.

Answer:
Nowadays, if a cell cannot express the AURKA gene, malignant neoplasms or cellular malignancies can be generated.
since it is related to the KRAS gene.
There is some scientific evidence or research that maintains that FOSL1 acts on another gene, AURKA, whose expression to date was thought to be independently regulated by the KRAS oncogene, and for which clinical trials are currently underway with a drug that inhibits it. .
Explanation:
Aurora kinase A also known as serine / threonine-protein kinase 6 is an enzyme that in humans is encoded by the AURKA gene.
