DNA - the molecules that carries the genetic instructions for life.
Where is DNA found and how many helix does it have?
nucleus, double-helix structure
DNA - deoxyribonucleic acid
mRNA - messenger ribonucleic acid
tRNA - transfer ribonucleic acid
What is the RNA that carries genetic information from DNA to the ribosome?
messenger ribonucleic acid
What is the RNA that brings the correct amino acids to the ribosome to build protein?
transfer ribonucleic acid
Where does transcription occur?
inside the nucleus
Where does the translation occur?
ribosome in cytoplasm
What are the three steps in transcription?
initiation, elongation, and termination
initiation - the beginning of transcription; the promoter is bound to the RNA polymerase
elongation - RNA polymerase moves along the DNA template strand, adding RNA nucleotides that are complementary to the DNA bases. This builds the mRNA strand
termination - the end of a gene, where the RNA polymerase stops and the DNA is no longer transcribed.
