Splicing

Question 1

what do eucaryotic genes have

Answer 1

introns (non-coding sequences)

Question 2

what does splicing do

Answer 2

cuts intons out of the mRNA prior to translation

Question 3

what does a prokaryotic gene have

Answer 3

coding regions

Question 4

what does an eukaryotic gene have

Answer 4

coding regions and non-coding regions

Question 5

what occurs in protein synthesis in procaryotes

Answer 5

bacterial gene has a single nucleotide sequence that encodes the amino acid sequence of a protein. Translation can begin at once (often before transcription of mRNA is complete)

Question 6

what recognises the special sequences that the signals in the DNA sequence determines where splicing occurs

Answer 6

small ribonucleotides snRNPs

Question 7

where does splicing occur

Answer 7

eucaryotes (bacteria)

Question 8

what is alternate splicing

Answer 8

splicing out different exons results in different proteins from the same gene
