Introns are parts of genes that do not directly code for proteins. (2)
Exons are parts of DNA that are converted into mature messenger RNA (mRNA). (6) The process by which DNA is used as a template to create mRNA is called transcription.
Answer:
A specialized cell means that even though they are similar, cells differ in size, shape or function depending on their role in our bodies. Each type of cell is modified to work in the way our bodies need it to. Specialized cell group together to form tissues.

Answer:
Cyclic electron flow
Explanation:
→The objective of this process is to synthesize ATP, so that proportion of ATP and NADPH could be met
→to prevent photo-inhibition of PS 1 and 11.
It involved only Photosystem 1 .(PS1) The process begins with the photo activation of chlorophyll molecule. <u>The excited electrons at higher energy levels, emitted from the chlorophyll molecule is captured by electron acceptors and return to the chlorophyll molecule ( rather than the usual PS) by chains of electron carriers . </u>
Therefore these electrons did not lose their energy as thermal energy. Instead large quantity of energy is conserved for ATP synthesis , via chemosomosisWith the resultant ATPs used in Calvin cycle for glucose, Amino acids and fatty acid production in light independent stage.
T<u>he continuous cyclic flow of these electron carriers(instead of non -cyclc flow or non cyclic photophosphorylation) ensures large quantity of energy conservation for the production of ATPs in chemosomosis.</u>
This explains the reasons for 30,000 molecules of ATPs consumed.
