HS-LS1-2 →

Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.

Clarification statement: Emphasis should be on how the DNA code is transcribed and translated in the synthesis of proteins. Types of proteins involved in performing life functions include enzymes, structural proteins, cell receptors, hormones, and antibodies.

Assessment boundary: Assessment does not include identification of specific cell or tissue types, whole body systems, specific protein structures and functions, or the detailed biochemistry of protein synthesis.

Performance Level Descriptions

Every Regents exam question on HS-LS1-1 is written to match one of the performance level descriptions (PLDs) below.

Level 1: Identify the evidence that supports the claim/explanation that the structure of DNA determines the structure of proteins or identify the explanation/claim using given evidence that the structure of DNA determines the structure of proteins.
Level 2: Describe the evidence that supports an explanation that the structure of DNA determines the structure of proteins.
Level 3: Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out essential functions.
Level 4: Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.
Level 5: Construct and revise an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.

NGSS Dimensions

Performance expectation HS-LS1-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices
  • Constructing Explanations and Designing Solutions
    • Construct an explanation based on valid and reliable evidence obtained from a variety of sources (including students’ own investigations, models, theories, simulations, peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.
Disciplinary Core Ideas
  • LS1.A: Structure and Function
    • Systems of specialized cells within organisms help them perform the essential functions of life.
    • All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.(Note: This Disciplinary Core Idea is also addressed by HS-LS3-1.)
Crosscutting Concepts
  • Structure and Function
    • Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal its function and/or solve a problem.
