Summary Introduction
Introduction:
Shotgun sequencing is a method in genetics that is used for sequencing long strands of DNA. Genome assembly is simply the sequencing of genome produced after fragmentation of chromosome and then those fragments are sequenced and resulting sequences have been set back together.

In next-generation sequencing, which of these advances allows for massively parallel sequencing?
a. Pieces of DNA are fixed to a surface, so we can tell which new nucleotides were added to each piece.
b. DNA sequences are read in real-time as nucleotides are added to each piece.
c. Each segment of the genome can be pieced back together through shotgun alignment
d. Single molecules of DNA can be read without the need for amplification.
Which are the limitations of using massively parallel sequencing to sequence a genome?
What is the purpose of the low temperature step in the PCR reaction?
a. To allow DNA polymerase to synthesize new DNA in the 3' to 5' direction
b. To permanently deactivate DNA polymerase
c. To allow primers to anneal to DNA templates
d. To allow DNA polymerase to synthesize new DNA in the 5' to 3' direction
