Protein Synthesis
Protein synthesis unit vocab
| Term | Definition |
|---|---|
| DNA | Provides the original instructions for making proteins/traits, contains deoxyribose sugar and has Thymine as a base |
| RNA | Single stranded nucleic acid with a ribose sugar, and has Uracil as a base |
| mRNA | messenger RNA; type of RNA that carries instructions from DNA in the nucleus to the ribosome in the cytoplasm |
| tRNA | transfer RNA; type of RNA that carries amino acids to the ribosome |
| Transcription | Process by which mRNA is synthesized from a DNA template, occurs in the nucleus of Euk cells |
| Translation | Process by which mRNA is read and an amino acid chain/protein is produced, occurs at the ribosome |
| Nucleus | Site of transcription |
| Ribosome | Site of translation |
| Codon | Three-nucleotide sequence on messenger RNA that codes for a single amino acid |
| Amino Acid | Monomer of protein, link together in a chain to form proteins/traits |
| Trait | Specific characteristic of an individual determined by their genes. |
| Protein Synthesis | Process of creating proteins through the steps of transcription and translation |
| Gene | A segment of DNA on a chromosome that codes for a specific trait |
| Gene Expression | Process of using a gene's instructions to create a protein. Sections of DNA are turned "on" to produce either an RNA molecule or a protein. |
| Cell Specialization/ Differentiation | Process in which cells develop in different ways, through gene expression, to perform different tasks |
| Environmental factors | External factors can change or influence what genes are expressed (and which genes are not) in an organism. |
