mRNA leaves the nucleus through the pores to enter the cytoplasm ( Codon = 3 bases)

Transcription begins - Cell gets message that a protein needs to be made & a portion of DNA unwinds exposing the gene that needs to be copied. Transcription begins - Cell gets message that a protein needs to be made & a portion of DNA unwinds exposing the gene that needs to be copied.

PROTEIN SYNTHESIS: TRANSLATION

PROTEIN SYNTHESIS: TRANSLATION. What is the genetic code?. the sequence of nt in mRNA the order of mRNA n.t . determines the order of amino acids that will bond to build a polypeptide the code is a triplet code: in mRNA, every 3 nucleotides codes for an aa called a CODON .

Changes in DNA

Changes in DNA. Analogy. We will be using a sentence as an analogy representing a strand of DNA. Our sentence is: The fat cat ate the wee rat. If this sentence represents a strand of DNA, what does each word represent ? (Each word represents a Codon for an A mino Acid)

Transcription and Translation

Transcription and Translation. Building Proteins. RNA Review. RNA is just like DNA, except that it is only one strand , instead of two. The other difference is that RNA replaces all of the THYMINE with URACIL. So, C still pairs with G. Cytosine with Gaunine But now, A pairs with U.
