What is Transcription? What is the purpose of transcription of RNA? What is the name of the new strand? The process of transferring the gene's DNA into RNA in the nucleus. Take the genetic information from DNA to the ribosome's The RNA copy of the gene is called the mRNA (It is a messenger). Making Proteins Step 1
What is the difference between DNA and RNA? mRNA differs from DNA by the substitution of uracil (U) for thymine (T). Also, only one strand of mRNA is needed when synthesizing proteins Making Proteins
Making Proteins • DNA and mRNA are both constructed by a chain of nucleotides.
Where the mRNA goes after Transcription? The mRNA leaves the cell's nucleus through nuclear pores to go to the site of translation, the ribosome's. mRNA Making Proteins
What is Translation? How are proteins made? It is the process where mRNA is a template to make proteins. To convert the mRNA into protein, tRNA (another molecule) is used to read the mRNA. Making Proteins Step 2
What is a codon/triplet? Example: What represents each codon/triplet? It is a sequence of 3 nucleotides at a time. CCG-UAC-GGA-UCG Each codon/triplet represents one amino-acid. Making Proteins Step 2
What is a polypeptide? It is a large protein, containing many molecules of amino acids, typically between 10 and 100. Making Proteins
How many RNA’s work in the protein synthesis? What is the function of each RNA? mRNA tRNA rRNA mRNA genetic (messenger) to the Ribosomes. tRNA (transfer) reads the code and carries the amino acid to be incorporated into the developing protein. rRNA (ribosomal) Site for proteins and carries the enzymes necessary for protein synthesis. Different Types of RNA
