1. RNA is like a computer disk or flash drive
RNA copies DNA Ch (p )
RNA = ribonucleic acid; has an extra oxygen, otherwise very similar to DNA
Big difference: instead of using the nucleotide Thymine (T), RNA uses nucleotide Uracil (U)
So now A—U and G—C
RNA is like a computer disk or flash drive
Copies information on one computer: DNA in nucleus
Takes info to another computer: ribosomes outside the nucleus

5. 1. mRNA = messenger RNA, the RNA acts as a messenger
RNA copies DNA Ch (p )
RNA comes in 3 types
1. mRNA = messenger RNA, the RNA acts as a messenger
Single uncoiled chain of RNA
Carries genetic info from DNA to outside the nucleus

7. Transcription = literally means rewriting ,
RNA copies DNA Ch (p )
Transcription = literally means rewriting ,
Rewriting info on DNA to a molecule of mRNA
Promoter region on DNA is where to start copying, termination region on DNA is where to stop copying

9. Single chain of about 80 nucleotides folded into hairpin shape
RNA copies DNA Ch (p )
RNA comes in 3 types
2. tRNA = transfer RNA, the RNA transfers the info from mRNA into proteins
Single chain of about 80 nucleotides folded into hairpin shape
Kind of looks like a t
Will discuss in 10.3

11. 3. rRNA = ribosomal RNA, RNA that makes the ribosomes
RNA copies DNA Ch (p )
RNA comes in 3 types
3. rRNA = ribosomal RNA, RNA that makes the ribosomes
Ribosomes are where proteins are made
Will discuss in 10.3

13. RNA copies DNA Ch (p )
