Question
Which of the following types of DNA is the most common in the human genome?
Question options:
Alu elements
DNA encoding exons
DNA encoding introns and untranslated RNA
Simple sequence DNA
A Single-nucleotide polymorphism (SNP, pronounced snip; plural snips) is a DNA sequence variation occurring when a Single Nucleotide — A, T, C or G — in the genome (or other shared sequence) differs between members of a biological species or paired chromosomes. For example, two sequenced DNA fragments from different individuals, AAGCCTA to AAGCTTA, contain a difference in a single nucleotide. Which portion of the human genome most likely contains the largest number of single nucleotide polymorphisms (SNPs). Which portion of the human genome most likely contains the largest number of single nucleotide polymorphisms (SNPs)
Question options:
The portion encoding exons
The portion encoding introns
The portion encoding transposons
The portion encoding simple sequence repeats (satellite DNA)
Question 5 0 / 1 pointExplanation / Answer
