the answer of the 1st question is Proteins. (According to DNA replication and RNA process and metabolism)
the answer of the 2nd question is RNA transcription takes place in the cytoplasm of a cell.
the answer of the 3rd question is nitrogenous bases, sugar, and phosphates, that is proved by the sequence of each strand of DNA.
the answer of the 4th question is 500 thymines, that is because each adenine bases changes to Thymine, so during DNA replication, so the number of adenine bases = number of thymines.

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.
