How does charging of tRNA takes place? Before an amino acid can be incorporated into a growing polypeptide, it must first be attached to a molecule called transfer RNA, or tRNA, in a process known as tRNA charging. The charged tRNA will then carry the activated amino acid to the ribosome. What is the charging […]
What is negative and positive charge?
What is negative and positive charge? There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel each other and unlike charges attract each other. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of […]

Are heavier hot wheels faster?
Are heavier hot wheels faster? The cars will be starting at the same height, but a heavier car will have more potential energy. That means more kinetic energy at the bottom of the hill, and more kinetic energy means more speed. That extra weight will help the car keep it’s speed better in the flat […]
Which of the following is a secondary protein structure?
Which of the following is a secondary protein structure? The most common types of secondary structures are the α helix and the β pleated sheet. Both structures are held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another. Images showing hydrogen bonding patterns […]
