# SB2: Genetic Information Expression

Obtain, evaluate, and communicate information to analyze how genetic information is expressed in cells.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SB2.a**: Construct an explanation of how the structures of DNA and RNA lead to the expression of information within the cell via the processes of replication, transcription, and translation.
- **SB2.b**: Construct an argument based on evidence to support the claim that inheritable genetic variations may result from: * new genetic combinations through meiosis (crossing over, nondisjunction); * non-lethal errors occurring during replication (insertions, deletions, substitutions); and/or * heritable mutations caused by environmental factors (radiation, chemicals, and viruses).
- **SB2.c**: Ask questions to gather and communicate information about the use and ethical considerations of biotechnology in forensics, medicine, and agriculture.

## Georgia Milestones coverage

- Biology (EOC). Cellular Genetics & Heredity. Cellular Genetics & Heredity (about 24% of the test; 11 points; shared with other standards, so count these points once and never add them up per standard)
