Observe the figure and answer the questions: What is the function of 'A'?

Translation can be characterised as a process in which new proteins are formed. The mRNA carries the information from DNA and transfer it into the ribosome. The letter A represents mRNA, and it functions as a messenger of the information.

Observe the figure and answer the questions: Explain the process that takes place in 'B.

The letter A represents mRNA and B represents ribosome. In the given illustration mRNA molecule carries information from DNA to ribosomes. In ribosomes, tRNA decodes the information of mRNA. The new protein is synthesized in ribosomes based on the information in mRNA by adding amino acids.

Observe the figure and answer the questions: Identify the parts A and B.

DNA and RNA are the genetic material of living organisms and are found to be present in the nucleus of the cells. The sugar molecules are different in both nucleic acids. RNA has ribose sugar while DNA contains deoxyribose sugar. They are also different in terms of nitrogenous bases, RNA contains uracil instead of thymine.
