frameshift: meaning, definition, pronunciation and examples
C2Specialized/Technical
Quick answer
What does “frameshift” mean?
A genetic mutation caused by the insertion or deletion of nucleotides in DNA, which alters the reading frame of the genetic code, usually resulting in nonfunctional proteins.

Definition
Meaning and Definition
A genetic mutation caused by the insertion or deletion of nucleotides in DNA, which alters the reading frame of the genetic code, usually resulting in nonfunctional proteins.
Any situation where the fundamental structure or framework for interpreting information is altered, causing subsequent elements to be misaligned or misinterpreted. Used metaphorically in computing, linguistics, or project management.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling conventions follow respective norms for compound words (typically hyphenated or solid).
Connotations
Identical technical meaning. In extended metaphorical use, perhaps more common in US tech/startup jargon.
Frequency
Equally rare in general discourse. Exclusively high-frequency within molecular biology, genetics, and bioinformatics contexts in both regions.

Common Mistakes When Using “frameshift”
- Using 'frameshift' as a verb in formal writing (e.g., 'The DNA frameshifted'). Prefer 'underwent a frameshift' or 'a frameshift occurred'.
- Confusing it with a point mutation, which substitutes but does not shift the frame.
FAQ
Frequently Asked Questions
In modern technical literature, it is most commonly written as one solid word: 'frameshift'. Older texts may use a hyphen: 'frame-shift'.
Extremely rarely. Most frameshifts are deleterious as they disrupt the protein sequence. There are a few documented cases in viral evolution or where a frameshift creates a novel, functional protein.
A nonsense mutation changes a codon to a stop codon within the correct frame. A frameshift mutation changes the reading frame itself, which often *leads to* a premature stop codon downstream but also alters all intervening amino acids.
Metaphorically, in fields like software development or linguistics, to describe a fundamental change in the underlying assumptions or structure that makes previous work or code misaligned. (e.g., 'The API update caused a frameshift in our library dependencies.')
A genetic mutation caused by the insertion or deletion of nucleotides in DNA, which alters the reading frame of the genetic code, usually resulting in nonfunctional proteins.
Frameshift is usually specialized/technical in register.
Frameshift: in British English it is pronounced /ˈfreɪmʃɪft/, and in American English it is pronounced /ˈfreɪmʃɪft/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Imagine a film projector (the 'frame') suddenly skipping a sprocket hole (a 'shift'). All the following pictures are now out of alignment. Similarly, in DNA, adding or removing a base shifts the 'reading frame' for all subsequent code.
Conceptual Metaphor
GENETIC CODE IS A TEXT; A MUTATION IS A TYPO. A frameshift is like deleting or adding a letter in a sentence, making all following words unreadable (e.g., 'The cat sat' -> 'Thc ats at').
