<span>Meat tenderizers contain proteases, which are enzymes that break down proteins. In meat, they break down the proteins that make up muscle, softening the meat in the process.
In DNA extraction, they break down the protein core, called a histone, that the DNA is supercoiled around. It's the supercoiling that allows a few meters worth of DNA to be compacted into a microscopic structure, and it also plays a role in gene regulation.
To a lesser extent, the proteases in the tenderizer can break down DNase enzymes (since enzymes are proteins too), which chop up DNA (to protect the cell from some viruses). Normally, the DNase is kept separate from the cell's DNA, but when you add detergent to the cells and break apart the membranes, all of the components can mix together and lead to unintended reactions.
When you break down the histone proteins, the DNA uncoils and stretches out, allowing you to see it and wind it around a stick (if your extraction protocol includes that step).</span><span>

Chloroplasts have chlorophyll which is where photosynthesis occurs. Photosynthesis does not occur in an animal cell,
Hope this answers your question
When twins are formed by the fertilization of two different egg cells and two sperm cells, the twins are referd to as dyzigotic twins
Dizygotic twins are characterized by each individual having unique genetical information, the opposite of monozygotic twins which have an identical genetical information.

Hope it helped,
Happy homework/ study/ exam!
