The right answer is A.Transcription uses uracil.
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The DNA and RNA molecules are chemically very close, but the second has an extra oxygen (in red on the right of the letters) on the sugars (riboses) that make up its nucleotides (the DNA actually contains deoxyribose). In addition, the thymine (T) of DNA is replaced by uracil (U) in RNA.
<span>The cilia and flagella of eukaryotic cells are made up of specifically designed microtubules. Microtubules are part of the cytoskeleton and are nucleated. They play an vital role in several cellular processes and also play a part in maintaining a cell's structure.</span>
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.
During gas exchange, the cell membrane of a single-celled organism has the same function as the respiratory system in humans. The respiratory system is a biological system which is composed of specific organs and structures such as nose, pharynx, larynx, trachea, bronchi and lungs that are used for gas exchange in humans. The primary function of the respiratory system is to transport oxygen into the body and to breathe out carbon dioxide, which is a waste product of cellular function
