Wk 3- Protein Synthesis & Enzymes

Genes: Genes contain the - for the production of p- They do not produce p-. There are ?,000 genes in DNA

Transcription: The process of making a - of DNA using -RNA. RNA polymerase - to the start region of the g? RNA polymerase reads the base of the template DNA strand Adds complimentary bases to form a -RNA chain

Transcription: When RNA polymerase reaches the end strand transcription is finished. mRNA and RNA polymerase - from DNA DNA strands re- mRNA strand needs p- before leaving the n-

Transcription: Every cell now has 1 strand of - DNA and 1 strand of - DNA made by m—. mRNA is capped at each end allowing passage through the n- p-. 3 bases on mRNA = a c? C? specify an a- a-

Translation: Translation is the process of p- chains from mRNA. mRNA outside the nucleus binds to r- tRNA has anticodon (a- a-) complementary to mRNA c-. Additional tRNA binds to r-. A- acids join= polypeptide

Translation: The codon sequence dictates anti codon/ amino acid to compliment tRNA molecule. A+? G+?

Enzymes: Accelerate b- processes and increase e-. Enzyme structure = p- + m- Enzymes act on a specific substrate, they are highly specific L- on lipids P- on proteins

Enzymes: Enzymes can be c- or a-. C- break down and release e-. A- use e- Activation of enzymes may involve increase/decrease in – level.

DNA construction: DNA is composed of; • N- base ( A- T- G- C-) • D- sugar • Ph- group
