46. C. To bring the DNA message to the ribosome

47. D. Anticodon; UGA

Explanation:

45. rRNA stands for ribosomal RNA. It is an important component of all ribosomes. It is non-coding RNA meaning it does not produce a protein. It is a ribozyme (an RNA with enzymatic activity) which carries out protein synthesis in ribosomes.

46. mRNA stands for messenger RNA. It is transcribed from DNA. After transcription, it goes to the ribosome where it is translated into protein.

47. tRNAs posses anticodons that are complementary to RNA codons. In RNAs, A pairs with U, and G pairs with C.

o-na [289]

Answer:

C). Bonds between atoms break and reform.

Explanation:

A Chemical reaction is defined as the process in which the substances(two or more) interact and form new substances by rearranging the atom structure of the substances. This process primarily consists of two steps i.e. breaking of chemical bonds that exist between the atoms in the original substances and the formation of new bonds to produce the new substance. Thus, the bonds break and reform. Hence, option C is the correct answer.

In animals, cell recognition:

adoni [48]

Answer:

The correct answer is D. involves proteins in plasma membranes.

Explanation:

Animal cells have several types of proteins embedded in their cell membrane. These proteins play an important role in the transport of molecules, cell recognition, and cell communication.

Recognition proteins are a type of glycoproteins present in the plasma membrane that allow one cell of the body to recognize the other body cells by making contact with recognition proteins of other cells. Receptors proteins allow cell-cell communication by receiving extracellular proteins.

These proteins are important for proper growth and development of the cell. Therefore the correct answer is D. involves proteins in plasma membranes.
