Single Recognition Particle (SRP) RNA is necessary for the targeting of proteins to the prokaryotic plasma membrane or to the eukaryotic endoplasmic reticulum membrane. Its job is to bind to the signal peptide of the membrane or secretory proteins coming from the ribosome at which time it forms a ribosome-nascent chain (RNC)-SRP complex.
SRP plays an important role in understsnding bacterial physiology, emphasizing the importance of proper membrane protein biogenesis, and demonstrates the ability of time-resolved quantitative proteomic analysis to provide new biological insights.
Answer:
embryological evidence or fossil evidence. give the answer choices if you can. they are vestigial structures.
Explanation:
Explanation: Bacteria are needed in the nitrogen cycle because plants and animals cannot directly use atmospheric nitrogen. Bacteria in the roots of plants trap nitrogen and convert it to ammonia and other nitrogen compounds which plants can then use to make protein
