What makes up the "tail" of an ATP molecule? 3 phosphate groups ribose adenine 2 phosphate groups
ZanzabumX [31]

Answer:

The tail of an ATP molecule is made up by 3 phosphate groups link together by the help of 2 high energy phospho anhydride bonds.

Explanation:

ATP or adenosine tri phosphate is an energy rich compound that contain adenine base, ribose sugar and 3 phosphate groups.

                  These 3 phosphate groups makes up the tail of ATP molecule.The 3 phosphate groups are designated as alpha phosphate,beta phosphate and gamma phosphate starting from the C5 atom of ribose sugar.

          When ATP undergo hydrolysis the terminal phosphate group or the gamma phosphate group is cleaved from the ATP molecule resulting in the formation of ADP and inorganic phosphate along with the generation of high amount of free energy that is utilized by the cell to perform various cellular and physiological activities.

What are the chromosomes called when they look like Xs​
Marina86 [1]

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....
