<u>Answer:</u>
<em>A plasma membrane is the cellular structure that makes it possible for a cell to differ structurally and biochemically from its surroundings. </em>
<u>Explanation:</u>
<em>Plasma membrane</em> is the surrounding of all the cells. The function of plasma membrane in a cell is to regulate the incoming and outgoing elements from the cell.
<em>Phospholipid bilayer</em> is the main composition of plasma membrane. It makes the cell different from each other structurally as well as makes the cell different in <em>chemical composition </em>too.
Answer:
The theory of punctuated equilibrium states that evolutionary change is characterised by short periods of rapid evolution followed by longer periods of stasis in which no change occurs. ... To meet this challenge, evolutionary biologists attempt to describe how and why evolutionary changes accumulate over time
Explanation:
Helium, with two protons, will have two electrons. In the chemical classroom, the proton count will always be equivalent to an atom's atomic number. This value will not change unless the nucleus decays or is bombarded (nuclear physics). Figure \(\PageIndex{1}\): The periodic table of the elements.
Helicases move along one strand of the duplex and push the opposing strand aside. They either migrate in the 3'-5' or 5'-3' orientation along the DNA or RNA (some can move in either direction).
- Living things need helicases, which are enzymes, to separate the double-stranded DNA in this instance from other nucleic acid strands.
- Helicases accomplish this by severing the hydrogen bonds that link the two strands.
- The DNA double helix's two strands are initially separated by an enzyme known as a DNA helicase.
- Each DnaB helicase winds the parental duplex by encircling one strand of the duplex DNA and moving in the 5′ to 3′ direction with respect to this ssDNA.
- Primers are created on occasion when DnaB interacts with primase.
