Answer:
Gene regulation in eucaryotic cells represents mechanisms that influence gene expression.
Explanation:
This gene expression is regulated via repressors or activators of transcription.
Gene expression is a process that contains information from a transcript gene and translates it into a functional gene product. End products of gene expression are proteins.
Gene regulation is a process that cells and viruses are using to regulate the transformation of gene information into gene products.
Transcription factors are those proteins that regulate gene transcription. Those factors help the real genes to enter the right cells in the body.
The expression of eukaryotic genes is controlled by transcription. This transcription is controlled by proteins that are connecting to regulatory sequences and change the RNA activity. Gene regulation process is developed by combining different proteins of regulation.
Answer:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Explanation:
Answer:
The uppermost portion of the mantle makes up the bottom portion of the lithosphere. On average, it is 30 kilometers thick, but its thickness depends on the age of that portion of the lithosphere and temperature and pressure conditions. The mantle consists largely of heavy ultramafic rock like olivine.
Explanation:
The mantle is made up of molten rock called magma. This magma circulates in currents determined by the cooling and sinking of heavier minerals and the heating and rising of lighter minerals. All but the very uppermost portion of the mantle is part of the asthenosphere, which refers to the liquid zone of the inner Earth.
