Ethidium bromide (Et Br) is used to stain the DNA fragments and will appear as orange coloured bands when kept under UV light.

Correct Option: C

Ethidium bromide (Et Br) is used to stain the DNA fragments and will appear as orange coloured bands when kept under UV light.

Human genome sequencing is a process that determines the complete DNA sequence of an organism’s genome at a single time. This requires sequencing all of an organism’s chromosomal DNA as well as DNA contained in the mitochondria and, for plants, in the chloroplast. Commonly used vectors for human genome sequencing are BAC (Bacterial artificial chromosomes) and YAC (Yeast artificial chromosomes).
