Answer to: Which of the following carries genetic information from the nucleus to the cytoplasm? a. transfer RNA (tRNA) b. messenger RNA (mRNA) c...
Studying sea urchins, biologist Paul Gross found that an unfertilized egg contains substances that function as morphogenetic determinants. They are located in the cytoplasm of the egg cell; i.e. , in that part of the cell’s pro- toplasm that lies outside of the nucleus. In the un...

Step-by-Step Solution:1. Understanding the Nervous System: The nervous system is divided into two main parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).2. Identifyi
The Hawaii researchers use essentially the same recipe used to make Dolly: Take an egg. Scoop out the nucleus, which contains the DNA genetic information, and discard. Take a cell of the animal you wish to clone and insert its DNA into the egg. Add chemicals to tell the egg to start ...
