i have some notes but before christmas break was here i had surgery so i didn't get to finish my notes in class and i don't understand much of my work so heres part of my notes:

DNA and RNA Differences:
#of strands for DNA? RNA?
sugar DNA? RNA?
Base that binds with Adenine DNA? RNA?
mRNA's function is to?
tRNA's function is to?

if you could help i would be very grateful thx.......

Of course, I'd be happy to help you understand your notes on DNA and RNA differences!

First, let's address each question one by one:

1. "# of strands for DNA? RNA?"
DNA (Deoxyribonucleic Acid) has a double-stranded structure, meaning it consists of two strands twisted together in a double helix. On the other hand, RNA (Ribonucleic Acid) is typically single-stranded. So, the answer is two strands for DNA and one strand for RNA.

2. "Sugar DNA? RNA?"
The sugar molecules in DNA and RNA are slightly different. DNA contains deoxyribose, which is why it is called deoxyribonucleic acid. RNA contains ribose, hence the name ribonucleic acid. So, the sugars in DNA and RNA are deoxyribose and ribose, respectively.

3. "Base that binds with Adenine DNA? RNA?"
Both DNA and RNA contain four different nitrogenous bases: Adenine (A), Thymine (T) in DNA, Uracil (U) in RNA, Guanine (G), and Cytosine (C). In DNA, Adenine pairs specifically with Thymine (A-T), forming a complementary base pair. In RNA, Adenine pairs with Uracil (A-U) instead of Thymine.

4. "mRNA's function is to?"
mRNA (messenger RNA) is responsible for carrying genetic information from DNA to the ribosomes in the cytoplasm of a cell. It acts as an intermediate molecule between DNA and protein synthesis. mRNA transcribes the DNA code and carries the instructions for protein synthesis.

5. "tRNA's function is to?"
tRNA (transfer RNA) plays a crucial role in protein synthesis. Its main function is to bring amino acids to the ribosomes. Each tRNA molecule has a specific anticodon sequence that is complementary to a codon on the mRNA. This allows tRNA to recognize and bind to the appropriate amino acid, ensuring that the correct amino acids are incorporated into the growing protein chain.

Now that I have explained the answers to your questions, I hope you have a better understanding of the differences between DNA and RNA and the functions of mRNA and tRNA. If you have any more questions or need further clarification, feel free to ask!
