Protein synthesis is a complicated process involving DNA being transcribed to RNA, which is then translated into amino acids. Complete the DNA-to-amino acid table for three consecutive codons with the appropriate nucleotides and amino acids using a codon table.

The genetic code is defined as a series of _______________ in _______________. (a) anticodons; tRNA (b) codons; DNA (c) anticodons; mRNA (d) codons; mRNA (e) codons and anticodons; rRNA
At least three types of RNA are required for protein synthesis. Compare and contrast mRNA, rRNA, and tRNA by moving the descriptions of their structure and function to the appropriate categories. Some phrases may describe all three types of RNA. mRNA in eukaryotes, can exist outside the nucleus acts as an enzyme for peptide synthesis composed of ribonucleic acid rRNA Answer Bank moves amino acids to the site of protein synthesis tRNA contains nucleotide triplets that code for specific amino acids has a convoluted structure with a three-base sequence called an anticodon moves genetic information out of the nucleus and into the cytoplasm mRNA, rRNA, and tRNA
Example: Beyonce has brown eyes. Her eyes look brown because her DNA codes for a brown pigment in the cells of her eyes. This is the gene that codes for brown eyes.

Make a Prediction: Why would an organism waste energy to make a copy of the gene with the mRNA molecule? In other words, why doesn't the body just send the original DNA molecule out to make the protein?
The correct order of genetic information transfer within biological systems is BEST described as RNA to DNA to Protein O DNA to RNA to Protein Structures to Function to Emergent Properties Genetic Information to Cells to Molecules
While mRNA strands are being created a sequence is sometimes miscopied. What is the best possible outcome for the cell should this take place? Top of Form The miscopied sequence codes for the same amino acids as the original sequence. The new sequence creates a protein that serves a different function from the original. The ribosomes will correct the mistake before the tRNA matches an amino acid to it. The mRNA will only be used to create non-critical proteins for the cell.
A crime has occurred, and you are asked to help solve it. A forensics detective brings you a sample from the crime scene of what they believe is the suspect's DNA and asks you for chemical analy Your study of this sample reveals the presence of adenine, thymine, ribose, and uracil, leading you to conclude that the sample is A pure DNA probably a mixture of DNA and RNA C pure RNA probably a mixture of rRNA and mRNA MAR 12 tv MacBook Air DII DD esc F6 F7 F8 F9 F10 F1 F1 F2 F3 F4 F5 &
