-
An enzyme that catalyzes formation of covalent bonds in the DNA sugar-phosphate backbone
Ligase
-
What taps into a cell's DNA copying machinery to rapidly produce millions of copies of a DNA sequence of interest
Polymerase chain reaction
-
Is a building block of a nucleic acid, consisting of a phosphate group, a nitrogenous base, and a five-carbon sugar
nucleotide
-
What is a triplet of mRNA bases that specifies a particular amino acid?
Codon
-
Who carries the information that specifies a protein?
The Messenger RNA (mRNA)
-
What is the genetic "code word" that corresponds to one aminoacid?
Codon
-
Who combines with proteins to form a ribosome, the physical location of protein synthesis? Also help to correctly align the ribosome and mRNA, and others catalyze formation of the bonds between aminoacids in the developing protein?
Ribosomal RNA (rRNA)
-
What molecules are "connectors" that bind an mRNA codon at one end and a specific amino acid at the other?
Transfer RNA (tRNA)
-
In the process of protein production which process cell copies a gene's DNA sequence to a complementary RNA molecule?
Transcription
-
In the process of protein production, which process the information in RNA is used to manufacture a protein by joining a sequence of aminoacids into a polypeptide chain?
Translation
-
Who is a sequence of DNA nucleotides that codes for a specific protein or RNA molecule?
Gene
-
WHich are the tree steps of the transcription?
- 1. initation
- 2. Elongation
- 3. Termination
-
Is the step of the transcription where the enzimes unzip the DNA double heliz, exposing the template strand.The RNA polymerase binds to the promoter, a DNA sequence that signals the gene's start.
