Answer:
I think you're referring to the Metaphase...
Explanation:
During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".
These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.
This "Zipping Up" makes the chromosomes more visible.
As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....
Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote. Sexual reproduction needs zygotes to reproduce that is why gametes are needed. Asexual reproduction doesn’t need gametes because there is only one parent and there is no fusion of gametes.
Answer:
E) horizontal gene transfer
Explanation:
Horizontal gene transfer can also be referred to as lateral gene transfer. It is the transmission of deoxyribonucleic acid (DNA) between different genomes.
Horizontal gene transfer has been shown to occur between different species, such as between prokaryotic and eukaryotic organisms.
Horizontal gene transfer is made possible by the existence of genetic elements, such as plasmids, transposons, and bacteriophages (bacteria that infects viruses).
