There's mRNA (messenger RNA) which sends messages from DNA to chosen places. (I think of this as a mail carrier and all the mail is from DNA.) There is tRNA (transfer RNA)which moves amino acids to chosen places. (I think of this as a driver of a bus and all of the people that board it are amino acids.) There is also rNA (ribonucleic RNA) which is a RNA component of the ribosome. Hoped I helped!
Answer:
By preventing the synthesis of DNA halting cell growth.
Explanation:
Fluorouracil and methotraxate prevent the synthesis of the neucleoside Thymidine thus preventing DNA replication and elongation. Methotraxate has a structure analogous to Folic acid which is important for thymidine synthesis. Thus, it acts as a competitive inhibitor on dihdrofolate reductase an enzyme that is essential for tetrahydrofolate formation, a folic acid derivative.
Fluorouracil acts by inhibiting thymidylate synthase which catalyses an essential step in Thymidine synthesis.

<h3>How do perceptions work?</h3>
In order to represent and comprehend the information or environment being given, perception involves the organization, identification, and interpretation of sensory data. All perception is based on neurological signals that are sent when the sensory system is chemically or physically activated.
<h3>Which 4 categories of perception are there?</h3>
The several senses are frequently used to divide up the various sorts of perception. This encompasses all forms of perception, such as those involving sight, smell, touch, sound, and taste. We usually employ all of these at once to perceive our surroundings.
