Which of the following statements describes the function of the sigma factor in prokaryotic transcription? - it catalyzes the removal of the introns to produce mature mrna to terminate transcription. - it causes the rna polymerase to detach from the mrna to terminate transcription. - it catalyzes the synthesis of mrna in a 5' to 3' direction to implement transcription elongation. - it attaches the amino acid to its cognate trna to initiate translation. - it facilitates the binding of rna polymerase to the promoter to initiate transcription.

All fats are part of a larger group known as lipids. lipids come in a variety of forms in food, including triglycerides, phospholipids, and sterols. choose the statement below that correctly describes the types of lipids found in foods. all fats are part of a larger group known as lipids. lipids come in a variety of forms in food, including triglycerides, phospholipids, and sterols. choose the statement below that correctly describes the types of lipids found in foods. triglycerides contain two fatty acids attached to a glycerol backbone. the body does not manufacture phospholipids, so they must be included in the diet. about 95% of the fat you eat is in the form of sterols. sterols like cholesterol have a ring structure.
