Answer:
DNA needs RNA to be copied.
Explanation:
The transcription process starts by DNA "Unziping" itself and the RNA polymerase matches up to its allele. This then copies the DNA and it is sent out to a ribosome for the translation process.
Short answer - to breathe.
Long answer - the black streaks on the trunk of birch trees are called lenticels, and their function is to enable the exchange of gases between the tree and the air. So, in a way, this makes the whole process of photosynthesis a lot easier for birch trees.
That would be a covalent bond. Hope this helps!
1. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
2. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.
3. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose
