RNA, Transcription, Translation

How is RNA different from DNA

1.RNA= Ribonucleic acid vs deoxyribonucleic acid

2.sugars= ribose vs deoxyribose

3.RNA= single stranded vs double stranded helix

4.4 bases AUGC vs ATGC

How is RNA different from DNA

Forms of RNA

1. messenger RNA (mRNA)

•carries instructions for protein synthesis from nucleus cytoplasm

Forms of RNA

2.Ribosomal RNA (rRNA)

• along with proteins make up ribosomes

• the site of protein synthesis

Forms of RNA

3.Transfer RNA (tRNA)

•reads code in mRNA

•transfers new amino acids onto growing polypeptide chain according to instructions in mRNA

Transcription (DNA RNA)

1.Process by which DNA is copied into mRNA

2.Carried out by RNA polymerase vs. DNA polymerase

3.occurs in the nucleus

Genetic code1. language of instruction is DNA/RNA

2.4 letters code ( either ATGC or AUGC)

3.Codes for 20 different amino acids

4.order of code specifies identify and order of a.a.

5.Each gene codes for a different protiens

Codons

•a group of 3 nucleotides in mRNA that codes for a specific a.a.

Translation (mRNA protein)

1.nucleotides in mRNA are decoded into a polypeptide

2.occurs in cytoplasm

Translation (mRNA protein)

Translation (mRNA protein)

Translation (mRNA protein)

The importance of protein

1.key to almost everything living cells do

2.how cells maintain shape, move, communicate

3. responsible for all our traits
