Ques:Answer the following question given this paragraph: Some lipids contain the element phosphorus as well as carbon, hydrogen, and oxygen. These lipids are called phospholipids. Two layers of phospholipid molecules make up the cell membranes of living things. In the Figure below , you can see how phospholipid molecules are arranged in a cell membrane. Q: What type of lipids contain the element phosphorus, carbon, hydrogen and oxygen? Choices: - filaments - eukaryotes - alleles - phospholipids A:

Ans:phospholipids

Ques:Answer the following question given this paragraph: A wobble base pair is a non-Watson Crick base pairing between two nucleotides in RNA molecules. The four main wobble base pairs are guanine-uracil, inocine-uracil, inosine-adenine, and inosine-cytosine. Wobble base pairs are fundamental in RNA secondary structure and are critical for the proper translation of the genetic code. Inosine is a nucleoside that is formed from the hydrolytic deamination of adenine. Structurally, it resembles guanine, but lacks the 2-amino group. This lack of the 2-amino group allows inosine to form base pairs with uracil, cytosine and adenine, making it a particularly wobbly base. Q: Of the four main wobble base pairs, guanine is paired with what? Choices: - thymine - cytosine - adenine - uracil A:

Ans:uracil
