Gel electrophoresis is used to create a unique dna fingerprint composed of different-sized dna fragments. what are the molecules responsible for cutting dna into fragments of different sizes prior to running gel electrophoresis?

Which of these is a major trend in land plant evolution? a) the trend toward smaller size b) the trend toward a gametophyte-dominated life cycle c) the trend toward a sporophyte-dominated life cycle d) the trend toward larger gametophytes

Dna, in the nucleus carries the genetic code for making proteins in ribosomes. in the diagram, b, represents the proteins produced. dna cannot leave the nucleus to carry the genetic information to the ribosome where proteins are produced. how does the genetic code get from the nucleus to the ribosome? what does a represent? now

Involving transcription and translaton. explain the causes and effects of damage to the genetic code.
