What are the parts of an RNA nucleotide?
- 1. A 5-carbon ribose sugar
- 2. A phosphate group
- 3. Nitrogenous bases
-
What are the differences between DNA and RNA?
- 1. DNA has deoxyribose sugar, RNA has ribose sugar
- 2. DNA has Thymine to pair with Adenine, RNA has Uracil to pair with Adenine
- 3. DNA is double stranded, RNA is single stranded
- 4. DNA is only found in the nucleus, RNA is found in the nucleus and cytoplasm
-
What is the job of tRNA?
- Transfer RNA reads the sequence of amino acids from mRNA and brings over the appropriate amino acid to the ribosome to link them together to form a protein. (Translation)
-
What is the job of mRNA?
Messenger RNA carries the directions from DNA out to the ribosomes so proteins can be made. (Transcription)
-
What is the job of rRNA?
- Ribosomal RNA is a part of the ribosome where translation occurs.
-
How do the bases in RNA relate to those in DNA?
- When RNA is paring with DNA:
- 1. Adenine pairs with Thymine
- 2. Uracil pairs with Adenine
- 3. Cytosine pairs with Guanine
- 4. Guanine pairs with Cytosine
-
What are the roles of DNA and RNA in transcription?
- A DNA molecule is copied onto a strand of mRNA, and then it carries the directions from DNA out to the ribosomes so proteins can be made.
-
What are the roles of DNA and RNA in translation?
- The tRNA starts reading mRNA at the AUG codon, and continues reading mRNA, bringing over the appropriate amino acids and linking them together to form a protein until a stop codon is reached. The protein is then shipped to where it needs to be utilized.
