B2- Protein Synthesis 0.0 / 5 ? BiologyProtein SynthesisGCSEEdexcel Created by: c//ana00Created on: 25-10-16 18:01 What is a gene? A gene is a section of DNA 1 of 15 What do the bases in a gene code for? Specific Proteins 2 of 15 How do you make proteins? By connecting amino acids in a specific order 3 of 15 How do cells know which order to put the amino acids in? The bases in a gene tells the cell which order to put the amino acids in 4 of 15 How many bases code for an amino acid? 3- It's called a triplet 5 of 15 Name 2 proteins a cell can produce Haemoglobin and Keratin 6 of 15 What makes proteins? Ribosomes 7 of 15 What are the man differences between mRNA and DNA? mRNA is single stranded, whereas DNA is double stranded. DNA is also longer than mRNA. 8 of 15 How is mRNA made? The DNA 'unzips' and the single strands are used as templates for the mRNA as bases pair with the bases on the DNA. This is Transcription 9 of 15 What is the difference between mRNA and DNA concerning bases? DNA has the base Thymine whereas mRNA hase the base Uracil instead of Thymine 10 of 15 After the DNA has been transcribed, what does the mRNA do? It moves out of the Nucleus 11 of 15 What does the mRNA molecule meet outside the Nucleus? A Ribosome 12 of 15 What brings the amino acids that match the mRNA code to the ribosomes? tRNA 13 of 15 What is the chain of amino acids called? A Polypeptide/Protein 14 of 15 What order do the amino acids follow? The order of the mRNA base triplets 15 of 15
