During gel electrophoresis, large DNA fragments will ____________________________ small DNA fragments.

Group of answer choices

a) migrate more rapidly than

b) migrate more slowly than

c) migrate at the same speed as

d) cause degradation of

e) separate into

Which of these is the best method for identifying genes contributing to common human diseases like hypertension?

Group of answer choices

a) A comparative genomics study

b) A microbiome study

c) A genome-wide association study

d) A test for Hardy-Weinberg equilibrium

e) A chi-squared goodness of fit test

Answer 1

During gel electrophoresis, large DNA fragments will ____________________________ small DNA fragments.

Correct option- b) migrate more slowly than

This is the correct option because smaller DNA will moves faster than large DNA in gel electrophoresis due to smaller DNA  migrate through the gel more quickly and therefore run faster than large DNA fragments to get separated as per the size of the DNA.

Which of these is the best method for identifying genes contributing to common human diseases like hypertension?

Correct option- c) A genome-wide association study

This is the best method for identifying the gene involved in common human diseases like hypertension based on the single nucleotide polymorphisms (SNPs) analysis across the genome
