1Gene expression involves the the "reading" of what
DNA
2How many chromosomes do humans have
46
3Gene expression leads to the synthesis of what
proteins
4What takes genetic instructions to the sites of protein synthesis
messenger ribonucleic acid
5What does mRNA do
takes genetic instructions to the sites of protein synthesis
6What do messenger ribonucleic acid molecules consist of
4 different nucleic acids strung together in various sequences
7When does DNA leave the nucleus
never
8Transcription
process of assembling a strand of mRNA that contains information of a gene
9transcript
trancribed strand of mRNA interspaced between protein coding genes
10Promoter
end of the gene where the RNA synthesizing enzyme RNA polymerase binds to initiate transcription
11What do transcription factors do
regulate the binding of RNA polymerase to the promoter
12RNA synthesyzing enzyme is called
RNA polymerase
13terminator
stop sequence where the RNA polymerase recognizes as the end point for transcription
14What does the RNA polymerase recognize as the end point for transcription
terminator
15coding sequences of DNA
exons
16noncoding sequences of DNA
introns
17Do initial transcripts contain introns or extrons
both
18List two things that happen in RNA splicing
introns are removed from the initial transcript, remaining exons are fused together
19Where are mRNA transcripts synthesized and spliced
within the nucleous
20where do mRNA transcripts leave the nucleous
pores in the nucleus envelope
21proteins are assembled out of what
amino acids
22Briefly summarize the central dogma of molecular biology
DNA, transcription, mRNA, translation, protein
