TRNA synthetases play a key role in protein biosynthesis by catalyzing the specific aminoacylation of tRNA at their 3' ends, a two step reaction termed "charging" of tRNA. The tutorial depicts the binding of glutaminyl-tRNA synthetase and tRNAGln. A uracil (U35) provides a key element for the recognition of tRNAGln by the synthetase enzyme. U35 of the tRNA is anchored in place by specific amino acids in the synthetase protein interacting ionically with the nearby backbone phosphates. Given what you know about ionic bonds and the phosphate backbone of RNA, what type of amino acids are involved in this interaction

Basic amino acids (positively charged)

Explanation:

The tRNA aminoacylation is an ATP-mediated process in which an aminoacyl-tRNA synthetase catalyzes the ligation of tRNAs to the corresponding amino acids. Moreover, amino acids are positively charged to interact with the phosphate groups of DNA which are negatively charged

im gonna compare the cells to jobs in factory. give brainliest

job in the factory //       cell organelle   //  

shipping/receiving

department                 plasma membrane    

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another

i think the answer is gold im not entirely sure
