For each of the following sequences, fill in either the DNA, the mRNA sequence, the tRNA anticodons, or the amino acid sequences that have been left blank. The amino acid charts are on the last page of these worksheets. 1. DNA 2.

What are three differences between RNA and DNA? The three main structural differences between RNA and DNA are, 1. RNA is single-stranded while DNA is double-stranded, 2. RNA contains uracil while DNA contains thymine, and 3. RNA has the sugar ribose while DNA has the sugar deoxyribose. 7. Where is DNA found in the cell? Nucleus 8. Where is RNA found in the cell? Cytoplasm 9. Name the three types of RNA and what they do. The three types and functions of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), which are present in all organisms. These and other types of RNAs primarily carry out biochemical reactions, similar to enzymes. 10. Write an mRNA strand that is complementary to the DNA strand AATTGC and code for the correct Amino Acid sequence. Show your work mRNA strand_ UUA__ACG LEU BER DNA strand _ AAU__ UGC ASN CYS 11. Explain protein synthesis (transcription and translation) in your own words. This process is called protein synthesis, and it actually consists of two processes: transcription and translation. The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein.
