What does the RNA world hypothesis state about ribozymes?
please help asap

Ribozymes were once more common than they are now. They eventually got replaced by proteins.

Ribozymes evolved after some proteins in cells were disabled by genetic mutations.

Ribozymes were once less common than they are now. Over time, they are replacing protein functions.

Ribozymes work on molecules that proteins cannot touch. Therefore, ribozymes will likely always exist in cells.

3points hurry! what is the relationship between biotechnology, sharkskin, and disease resistance? bioengineers have developed an artificial sharkskin that does not allow resistant bacteria to grow on it. disease-causing microbes have been genetically modified to keep them from infecting the skins of sharks. scientists have created a device that can be attached to the skins of sharks that dramatically increases their abilities to resist disease. sharkskin produces many chemicals that can be collected and used to create antibiotics.
