DNA carries _____________ in the cells __________.

RNA Ribonucleic Acid Contains Ribose Single Stranded Adenine binds with Uracil not Thymine

Ribonucleic Acid

Contains Ribose

Single Stranded

Adenine binds with Uracil not Thymine

Types of RNA mRNA - messenger, carries info from nucleus to ribosome tRNA- Transfer, carries amino acids to ribosome rRNA- ribosomal, helps form the ribosome and catalyzes protein synthesis

mRNA - messenger, carries info from nucleus to ribosome

tRNA- Transfer, carries amino acids to ribosome

rRNA- ribosomal, helps form the ribosome and catalyzes protein synthesis

RNA Transcription Transcription is the process of transferring information from DNA to RNA RNA polymerases build complementary RNA strands.

Transcription is the process of transferring information from DNA to RNA

RNA polymerases build complementary RNA strands.

RNA Transcription To copy in the same words but in a different form EXAMPLE MAKE A PROTEIN FOR ENERGY PRODUCTION MAKE A PROTEIN FOR ENERGY PRODUCTION

To copy in the same words but in a different form

EXAMPLE

MAKE A PROTEIN FOR ENERGY PRODUCTION

MAKE A PROTEIN FOR ENERGY PRODUCTION

Steps of Transcription Helicases unwind DNA RNA Polymerase binds to promoter RNA Polymerase transcribes a mRNA RNA Polymerase falls off mRNA is spliced mRNA sent to ribosome

Helicases unwind DNA

RNA Polymerase binds to promoter

RNA Polymerase transcribes a mRNA

RNA Polymerase falls off

mRNA is spliced

mRNA sent to ribosome

mRNA Splicing Introns- regions of unused DNA Exons- regions of DNA used to make protiens Introns are removed before the mRNA is sent out of the nucleus EXons are the EXpressed portions of DNA

Introns- regions of unused DNA

Exons- regions of DNA used to make protiens

Introns are removed before the mRNA is sent out of the nucleus

EXons are the EXpressed portions of DNA

Protein Synthesis All Protein synthesis takes place on a ribosome Protein synthesis is called translation mRNA information is translated into a protein

All Protein synthesis takes place on a ribosome

Protein synthesis is called translation

mRNA information is translated into a protein

Translation To copy in the same words but in a different language EXAMPLE MAKE A PROTEIN FOR ENERGY PRODUCTION Bilden Sie ein Protein für Energie produktion

To copy in the same words but in a different language

EXAMPLE

MAKE A PROTEIN FOR ENERGY PRODUCTION

Bilden Sie ein Protein für Energie produktion

Translation mRNA’s match up with tRNA’s anticodons Amino acids attach to each other at ribosome.
