QUESTION 1:
The following DNA sequence occurs near the middle of the coding region of a gene. DNA 5' A A T G A A T G G* G A G C C T G A A G G A 3'
There is a G to A base change at the position marked with an asterisk. Consequently, a codon normally encoding an amino acid becomes a stop codon.
How will this alteration influence DNA replication?
QUESTION 2:
The following DNA sequence occurs near the middle of the coding region of a gene. DNA 5' A A T G A A T G G* G A G C C T G A A G G A 3'
There is a G to A base change at the position marked with an asterisk. Consequently, a codon normally encoding an amino acid becomes a stop codon.
How will this alteration influence transcription?
QUESTION 3:
The following DNA sequence occurs near the middle of the coding region of a gene. DNA 5' A A T G A A T G G* G A G C C T G A A G G A 3'
There is a G to A base change at the position marked with an asterisk. Consequently, a codon normally encoding an amino acid becomes a stop codon.
How will this alteration influence translation?
Explanation / Answer
1) the alternation in base do not effect replication, the replication phenominon continues with out any effect. proof reading enzymes can alter these sort of repairs.
2) the transcription will also take place with change in aminiacid sequence.
3) this alteration in base effects translation lot by producing truncated protein, some times it may not even traslate to protein.
