Answer:

b: many genes code for RNAs that function directly in the cell

Explanation:

<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.

The processes that take place for gene to be successfully expressed are;

  • Replication
  • Transcription
  • Translation

<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.

<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.

Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.

<em>The correct option is b.</em>

How are cellular resperation and photosynthesis related
Colt1911 [192]

Answer: Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process. Hope this helps :)
