Joke of the Day:

DNA and Protein Synthesis Replication/Transcription/Translation

Terms DNA: Deoxyribonucleic acid

Anatomy of DNA DNA: Deoxyribonucleic acid 1. Nucleotide: (monomer) Building block of DNA. Consists of Nitrogenous base, phosphate group, and sugar

Anatomy of DNA DNA: Deoxyribonucleic acid Read in groups of 3 nucleotide (bases) called TRIPLET CODE 1. Nucleotide: Building block of DNA. Consists of Nitrogenous base, phosphate group, and sugar 2. 4 nitrogenous bases: Adenine Thymine Guanine Cytosine

Terms DNA: Deoxyribonucleic acid 1. Nucleotide: Building block of DNA. Consists of Nitrogenous base, phosphate group, and sugar 2. 4 nitrogenous bases: 3.Chargraff’s Rule Adenine A-T Thymine G-C Guanine Cytosine

Replication a. To make an exact copy of DNA so during cell division both cells are the same b. Occurs in the nucleus during S phase of cell cycle.

Protein Synthesis 1st Step: Transcription: 1. RNA polymerase unzips DNA and reads one side of DNA strand 2. mRNA is formed. (messenger) mRNA: single stranded mirror image of DNA

Protein Synthesis Transcription: 1. RNA polymerase unzips DNA and reads one side of DNA strand 2. mRNA is formed. (single stranded) (messenger) mRNA: single stranded mirror image of DNA Codon: Series of 3 mRNA nucleotides(bases)

Protein Synthesis Transcription: 1. RNA polymerase unzips DNA and reads one side of DNA strand 2. mRNA is formed. (single stranded) (messenger) mRNA: single stranded mirror image of DNA Codon: Series of 3 mRNA nucleotides(bases) Uracil: RNA’s version of Thymine (DNA has “T”. RNA has “U”.) DNA Strand - ATCG mRNA compliment - UAGC

Protein Synthesis 2nd Step: Translation Decoding of a mRNA message into a polypeptide chain (protein)

Protein Synthesis 2nd Step: Translation Decoding of a mRNA message into a polypeptide chain (protein) - this happens at a ribosome (rRNA) - tRNA translates the mRNA message

Protein Synthesis 2nd Step: Translation Decoding of a mRNA message into a polypeptide chain (protein) - this happens at a ribosome (rRNA) - tRNA translates the mRNA message - tRNA carry amino acids that are fused together with a peptide bond to form a protein

Protein Synthesis 2nd Step: Translation Decoding of a mRNA message into a polypeptide chain (protein) Anticodon: series of 3 tRNA nucleotide (bases) Ex- mRNA (codon) - AUGC tRNA (anticodon)-UACG

Protein Synthesis Translation mRNA is read at the ribosome and tRNA is created (single stranded) Anticodon: series of 3 tRNA bases Amino acid: building block of protein (monomer)

Protein Synthesis Translation mRNA is read at the ribosome and tRNA is created (single stranded) Anticodon: series of 3 tRNA nucleotide bases Amino acid: (monomer) building block of polypeptide Polypeptide: (protein) chain of amino acids

Protein Synthesis Big Picture

Stem Cells Unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity. Potential to develop into many different cell types in the body They serve as a sort of internal repair system, dividing essentially without limit to replenish other cells. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. http://www.youtube.com/watch?v=DealmN94tRw&feature=related
