Prokaryotes and eukaryotes package their DNA molecules with protein in structures called chromosomes. A prokaryotic chromosome is circular and resides in a cell region called the nucleoid.
<span>Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils
or animal fats which conform to ASTM D6751 specifications for use in
diesel engines. Biodiesel refers to the pure fuel before blending with
diesel fuel.
i hope this helps you in the time of your need!! =D

Answer:
<em>Endothermic reactions: separation of solute molecules , separation of solvent molecules</em>
<em>Exothermic: formation of solute-solvent interactions</em>
Explanation:
An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.
An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.
Answer:
25000 fragments
Explanation:
A restriction enzyme can cut a random DNA sequence once per every 4^n where n = number of bases in the recognition site of enzyme.
There are 6 bases in Xbal's recognition site (TCTAGA) so it will cut once per every 4^6 = 4096 bases (4kb).
Total genomic size = 100000kb
So expected number of fragments = Total genomic size/Size of one fragment
= 100000/4
= 25000 fragments
