B. an atom
Atoms are the basic units of matter and the defining structure of elements.
The correct option is D.
Transcription is the process by which the information in a DNA molecule is copied into an mRNA strand. Replication is the process by which two new strands of DNA are formed from a single parent DNA. Both the DNA and the RNA are composed of four different bases, three of the bases are the same while one is different for the DNA and RNA. It is only the RNA that has uracil while it is only the DNA that has thymine. Thus, Uracil is involved during the process of transcription since it is an mRNA strand that is formed while thymine is the one involved during the process of replication since it is a DNA molecule that is formed.<span />
Answer:
S phase of the cell cycle
Explanation:
During Mitosis, DNA is replicated during the S phase (Synthesis phase) of Interphase.
Carnivores also rely on plants because the herbivores are their source of food, and the plants feed the herbivores.
