Question

Goals of ATAC-seq and ChIP-seq

Option 1: ATAC-seq identifies open chromatin regions, ChIP-seq identifies protein-DNA interactions.
Option 2: ATAC-seq identifies histone modifications, ChIP-seq identifies gene expression levels.
Option 3: ATAC-seq measures RNA expression, ChIP-seq analyzes DNA methylation.
Option 4: ATAC-seq identifies DNA sequence variations, ChIP-seq measures RNA folding.

Answer 1

ATAC-seq identifies open chromatin regions, ChIP-seq identifies protein-DNA interactions. Both techniques help study gene regulation and chromatin structure.

Step-by-step explanation:

ATAC-seq and ChIP-seq are both techniques used in molecular biology to study gene regulation and chromatin structure. ATAC-seq identifies open chromatin regions, which are areas of DNA that are accessible and active. ChIP-seq, on the other hand, identifies protein-DNA interactions, specifically binding sites of proteins on the DNA. The main goals of ATAC-seq and ChIP-seq are to understand the accessibility of DNA and the binding of proteins to DNA, which are key factors in gene expression and regulation.
