PROTEIN SYNTHESIS VOCABULARY QUIZ
| Term | Definition |
|---|---|
| using the coded information in DNA to assemble amino acids into a specific sequence | translation |
| the enzyme that controls the manufacturing of mRNA from DNA | RNA polymerase |
| sections of transcribed mRNA that do not code for amino acids and are "snipped out" fo the mRNA strand | introns |
| the organelle that actually assembles the polypeptide chain | ribosome |
| the enzyme that controls the replication of DNA | DNA polymerase |
| sections of mRNA that are actually read as codons when making the protein; they are spliced together during mRNA processing | exons |
| a chain of nucleotides in RNA that contain the anticodon; these RNA strands bring the amino acids to the ribosome during the building of the polypeptide chanin | tRNA |
| almost every cellular and extracellular substance made by a cell | structural protein |
| UAA, UAG, and UGA terminate the translation process when they reach the A site of the ribosome | stop codons |
| a 3 base sequence in mRNA that codes for a particular amino acid | codon |
| the process that places the DNA code into a sequence of bases in an mRNA molecule | transcription |
| formed by the transcription of the DNA molecule | mRNA |
| sum of all of an organisms life processes | metabolism |
| the 3 base sequence in tRNA that is complimentary to an mRNA sequence | anticodon |
| AUG begins the process of translation when it reaches the A site of the ribosome | start codon |
| the portion of the nucleotide that can be called the alphabet of life (A, T, C, G) | nitrogen base |
| a type of RNA that combines with various proteins to form a ribosome in the cytoplasm | rRNA |
| the overall process of building a protein using a DNA code | protein synthesis |
| the process of DNA makeing an exact copy of itself | replication |
| a three part subunit of DNA and RNA; made up of a phosphate group, ribose sugar, and one of four nitrogen bases | nucleotide |
