Question

Proteins that use energy from ATP hydrolysis to change the locations and compositions of nucleosomes are called ATP-dependent___complexes.

Answer 1

ATP-dependent chromatin remodeling complexes use energy from ATP hydrolysis to change the locations and compositions of nucleosomes. They play a crucial role in regulating gene expression by remodeling the chromatin structure.

Step-by-step explanation:

The proteins that use energy from ATP hydrolysis to change the locations and compositions of nucleosomes are called ATP-dependent chromatin remodeling complexes. These complexes play a crucial role in regulating gene expression by remodeling the chromatin structure, which can either facilitate or hinder the access of transcription factors to specific DNA regions.

ATP-dependent chromatin remodeling complexes use the energy from ATP hydrolysis to slide, reposition, and restructure nucleosomes, allowing for the opening of chromatin and the exposure of DNA sequences that need to be transcribed. This process is important for various cellular processes, including DNA replication, repair, and gene regulation.

Answer 2

Chromatin-remodeling

Step-by-step explanation:

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling.

Chromatin-remodeling complexes use energy from ATP hydrolysis to alter the arrangement of nucleosomes, making the DNA more accessible to other proteins.
