Answer:
Size of the band varied
Explanation:
In the given question, the options are not provided but based on the information provided in the question, it can be predicted.
When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.
When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.
Thus, the size of the band varied is correct.
Answer:
An efficient way to search for and insert a value in a cell when the desired value is stored elsewhere in the worksheet or even in a different workbook is by using lookup functions.
Explanation:
- Lookup function is the built in function of excel that helps in returning the certain value form specific row or column.
- When the value is stored in the worksheet we can easily insert that desired value in the cell by the use of lookup functions.
- VLOOKUP and HLOOKUP are the lookup unctions that searches the value in column and row respectively.
A silent mutation. This is when the new codon will work just as well as the old one without changing the amino acid shape.
<span>An ionic bond is a complete transfer of electrons from one atom to another. This generally happens between atoms that have opposite electronegativity. This means one has very few atoms in their outer shell, while the other has many. A common example of an ionic bond is that of salt, with Na and Cl. Sodium has one electron in its outer shell, in which it transfers to chloride to make an ionic bond.

Ionic bonds are usually found in dry forms such as salts and are found in compounds throughout the human body. Ionic compounds are generally water soluble.</span>
DNA<span> - As you recall, DNA is formed in the shape of a double helix. The double strands of DNA are held together by hydrogen bonds. Each single strand has a backbone made of sugar and phosphate, as well as either a purine (adenine or guanine) or pyrimidine (cytosine or thymine). Each purine is connected to a pyrimidine through a hydrogen bond, giving the double DNA strand strength, and flexibility. This bond holds the two sides of DNA together, each bond contributing to the overall strength of DNA. When DNA is replicated, special enzymes known as DNA helicase "unzip" DNA and these bonds are broken so the two strands can be individually replicated.</span>
