Genetics

Chapter 2 Science 30. Genetics. What is genetics?. Genetics is the study of how traits are passed from parent to offspring Nucleus of cells contain genetic material organized into chromosomes. Chromosomes carry genes, units of hereditary. Each chromosome contains many different genes.

REPLICATION

REPLICATION. Chapter 7. The Problem. DNA is maintained in a compressed, supercoiled state. BUT, basis of replication is the formation of strands based on specific bases pairing with their complementary bases. ? Before DNA can be replicated it must be made accessible, i.e., it must be unwound.

DNA Replication

DNA Replication. DNA Length. DNA molecules are surprisingly long. The nucleus of a human cell contains more than 1 meter of DNA. DNA must be folded and coiled in order to fit in such a small space. Structure of Chromosomes. Chromosomes are made up of chromatin .
