Process in which mRNA ( messenger) is synthesized from the template DNA | transcription |
Process in which mRNA attaches to the ribosome and a protein is assembled | translation |
A self-replicating material present in nearly all living organisms as the carrier of genetic information in chromosomes | DNA |
A nucleic acid that is single-stranded and plays a major role in carrying out (completing) protein synthesis ( protein making) | RNA |
Twisted-ladder shape of DNA, formed by two nucleotide strands twisted around each other | Double Helix |
Permanent change in a cell's DNA, ranging from changes in a single base pair to deletions of large sections of chromosomes | Mutation |
Complex process where the original(parent) strands of DNA in a double helix are separated and each one is copied to produce a new identical daughter strand. | replication |
Sequence of three DNA or three RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis | Codon |
