gene (molecular term)

Answer 1

a segment of DNA that can be transcribed into RNA and the regulatory sequence that makes transcription possible

Question 2

consenus sequence

Answer 2

the nucleotide sequence of a particular segment of DNA that is conserved amongst different individuals

Question 3

RNA processing (co-transcriptional)

Answer 3

the sum of RNA modifications made to eukaryptic RNA prior to export from the nucleus

Question 4

what are RNA modifications

Answer 4

capping, splicing, polyadenylation

Question 5

alternative splicing

Answer 5

production of different mRNAs from the same primary transcript die to variations in the splicing pattern

Question 12

promoter

Answer 12

a set of DNA sequences to which RNA polymerase (and/or other TFS) binds to initiate transcription

Question 13
