What is used to sort DNA into different lenghts?
Gel Electrophoresis
What role do ddNTPs play in the process of DNA replication?
During DNA replication, ddNTPs (dideoxynucleotide triphosphates) are used to terminate the growth of DNA strands by preventing the addition of more nucleotides. This is important in techniques like Sanger sequencing, where ddNTPs are used to create DNA fragments of different lengths for analysis.
What is the function of a ddNTP in DNA sequencing and how does it impact the sequencing process?
A ddNTP (dideoxynucleotide triphosphate) is used in DNA sequencing to terminate the DNA strand during replication. When a ddNTP is incorporated into the growing DNA strand, it prevents further elongation, resulting in fragments of varying lengths. These fragments are then separated by size to determine the sequence of the original DNA strand.
What is the term used to describe the shape of DNA?
The term used to describe the shape of DNA is a double helix. It consists of two strands that coil around each other in a spiral.
Dideoxyribonucleotide chain-termination is a method of?
Dideoxyribonucleotide chain-termination is a method used in DNA sequencing to determine the sequence of nucleotides in a DNA molecule. It involves terminating DNA synthesis at specific bases by incorporating dideoxyribonucleotides (ddNTPs) into the growing DNA strand, which lack the 3' hydroxyl group needed for further elongation. This results in a series of fragments of varying lengths that can be separated by size to reveal the DNA sequence.
