Chapter 14 Flashcards
The process by which information encoded in DNA directs the synthesis or proteins or, in some cases, RNAs that are not translated into proteins and instead function as RNAs
Gene Expression
The synthesis of RNA using a DNA template
Transcription
The DNA strand that provides the pattern for ordering, by complementary base pairing, the sequence of nucleotides in an RNA transcript.
Template Strand
The DNA strand whose base sequence is similar to its primary transcript (RNA)
Coding Strand
An enzyme that links ribonucleotides into a growing RNA chain during transcription, based on complementary binding to nucleotides on a DNA template strand
RNA Polymerase
A specific nucleotide sequence in the DNA of a gene that binds RNA polymerase, positioning it to start transcribing RNA at the appropriate place.
Promoter
A DNA sequence in eukaryotic promoters crucial in forming the transcription initiation complex.
TATA Box
Modification of RNA primary transcripts, including splicing our of introns, joining together of exons, and alteration of the 5’ and 3’ ends
RNA Processing
After synthesis of a eukaryotic primary RNA transcript, the removal of portions of the transcript that will not be included in the mRNA and the joining together of the remaining portions.
RNA Splicing
Alternative Splicing
Introns
Exons
Messenger RNA (mRNA)
