The information content of DNA is in the form ofspecific sequences of __________
|
Nucleotides
|
________ are the links between genotype andphenotype
|
Proteins
|
__________, the process by which DNAdirects protein synthesis, includes two stages:transcription and translation
|
Gene expression
|
________ is the bridge between genes and theproteins for which they code
|
RNA
|
_________ is the synthesis of RNA underthe direction of DNA
|
Transcription
|
Transcription produces ____________
|
Messenger RNA(mRNA)
|
_________ is the synthesis of a polypeptide,using information in the mRNA
|
Translation
|
__________are the sites of translation
|
Ribosomes
|
In ____________, translation of mRNA can beginbefore transcription has finished
|
Prokaryotes
|
In a eukaryotic cell, the ____________separates transcription from translation
|
Nuclear envelope
|
Eukaryotic RNA transcripts are modified through________ to yield finished mRNA
|
RNA processing
|
A_____________ is the initial RNAtranscript from any gene prior to processing
|
primary transcript
|
The central dogma is the concept that cells aregoverned by a cellular chain of command: __________
|
DNA > RNA > protein
|
The flow of information from gene to protein isbased on a___________: a series ofnonoverlapping, three-nucleotide words
|
triplet code
The words of a gene are transcribed intocomplementary nonoverlaping three-nucleotidewords of mRNAThese words are then translated into a chain ofamino acids, forming a polypeptide© 2011 |
During transcription, one of the two DNA strands,called the template strand, provides a templatefor ordering the sequence of complementarynucleotides in an RNA transcript
