DNA
RNA
proteins

Question 2.2. Which sentence correctly describes transcription? (Points : 1)
RNA is the direct result of DNA transcription.
Proteins are the direct result of RNA transcription.
Protein transcription takes place in the nucleus of a cell.
RNA transcription takes place in the cytoplasm of a cell.
Question 3.3. What is the DNA backbone made of? (Points : 1)
a nitrogenous base and a sugar molecule
nitrogenous bases, sugar, and phosphates
sugar and phosphates
a polymer of nitrogenous bases
Question 4.4. If a segment of one strand of a DNA molecule has 500 adenine bases, how many thymine bases does the other strand have? (Points : 1)
500
250
0
You can't tell from that data.
1. Proteins
After RNA is formed, it is transported out of the nucleus and goes to the cytoplasm. From the cytoplasm, it goes into the ribosomes, where protein synthesis occurs. Together with transfer RNA (tRNA), mRNA will direct protein synthesis.
2. RNA is the direct result of DNA transcription.
Transcription is a process where DNA is transcribed into messenger RNA (mRNA). This carries all the information that will be needed to synthesize proteins.
3. Sugar and phosphates
The backbone of DNA, is made of sugar and phosphate. They form the structural framework of nucleic acids. They are arranged alternately, sugar-phosphate group-sugar and so on. The backbone refers to the sides of the DNA "ladder."
4. 500
In base pairing, guanine and cytosine pair up and adenine pairs up with thymine. Fore every adenine, there will be a thymine. If there are 500 adenine bases, there will be one for each one. So the answer is 500.
Answer:
What is best definition of biology?
The word biology is derived from the greek words /bios/ meaning /life/ and /logos/ meaning /study/ and is defined as the science of life and living organisms. An organism is a living entity consisting of one cell e.g. bacteria, or several cells e.g. animals, plants and fungi.
Explanation:
Producers are living beings at the beginning of the food chain. For example, plants are producers. Producers are always the first link in a food chain. Producers are living beings capable of producing their own living matter.
Consumers are living beings who can not produce their own organic matter alone. To grow and grow they need to consume other living things. For example, animals or humans are consumers. The primary consumer consumes the producers, and the secondary consumer consumes the primary consumers, and so on.
Decomposers are living things that degrade organic matter, transform it and return it to nature in the form of mineral elements. Decomposers are living beings responsible for "cleaning" the earth and recycling dead living organisms into organic matter that can in turn be consumed by producers. For example, maggots are decomposers.

to cause the second organism to produce proteins
The statement 'to cause the second organism to produce proteins' BEST describes why scientists sometimes insert the DNA of one organism into a second organism.
In conclusion, the statement 'to cause the second organism to produce proteins' BEST describes why scientists sometimes insert the DNA of one organism into a second organism.
