Answer:
A polar molecule simply means the charges are not exactly even throughout the molecule. Some parts are slightly negative (outside the oxygen), and some parts are slightly positive (outside the hydrogen atoms). Water is polar because the highly electronegative oxygen atom attracts electrons to it, making the region around the oxygen more negative than the areas around the two hydrogen atoms. This concept is important to understand how water bonds.
Answer and Explanation:
Translation is the process by which mRNA information is encoded into appropriate amino acids. The stages of translation are divided into initiation, elongation and termination. In initiation, ribosome attaches to start codon. A Complementary tRNA base pairs with the codon
. In elongation, the ribosomes help form peptide bond between amino acids and break the bond between tRNA and the amino acid. In termination, a release protein binds to a stop codon and protein is released.
Answer:
In many cases, cloning involves inserting the gene into a piece of circular DNA called a plasmid, which can be copied in bacteria. ... If two DNA molecules have matching ends, they can be joined by the enzyme DNA ligase. DNA ligase seals the gap between the molecules, forming a single piece of DNA.
The amount of energy before a process occurs is equal to the energy after the process occur.
