Answer:
All cells are surrounded by a cell membrane. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.
Explanation:
Answer:
The correct option is: e. molecules move across the plasma membrane against their concentration gradient
Explanation:
Active transport refers to the <u>movement of the particles or molecules from higher concentration to lower concentration, across the plasma membrane of a cell.</u> This transport requires cellular energy as the movement of the molecules is <u>against the concentration gradient</u>.
Active transport can be divided into primary and secondary active transport.
1.The thermosphere: is used for orbitting satellites and increases in temperature as altitude increases.
2.Convection currents in the mantle cause the movement of crustal plates.
A technique used in determining the protein binding region in dna (e.g, binding region of RNA polymerase) is called DNA footprinting
One technique used to determine protein binding regions (eg, RNA polymerase binding regions) of DNA is called DNA footprinting. A DNA footprint shows where a protein binds to a DNA molecule. In this technique, a pure DNA fragment labeled with 32 P at one end is first isolated. A trace amount of DNA endonuclease is then added to the mixture of core protein and radiolabeled DNA. RNA sequencing (RNA-Seq) harnesses the power of high-throughput sequencing methods to gain insight into the cellular transcriptome. Compared to previous Sanger sequencing and microarray-based methods, RNA-Seq offers much broader coverage and resolution of the dynamic nature of the transcriptome.
