18
Q

what is the promoter region

A

where RNA polymerse binds

19
Q

what is the body in a gene

A

begins with the start codon

20
Q

what is the termination signal in a gene

A

stop codon and signal for polyerse to detach

21
Q

What is the machinery

A

transcription factors and RNA polymerase

22
Q

what are transcription factors

A

recognize promotor region and signal polymerse to bind

23
Q

what is the RNA polymerse

A

Pulls DNA strands apart and creates RNA strand from DNA template strand

24
Q

What are the three steps to transcription

A

Initiation, elongation, and termination

25
Q

What is initiation

A

transcription factors find and attach to a promotor

26
Q

RNA attaches to

A

DNA

27
Q

What does the polymerse do

A

separates DNA and begins synthesis of RNA from DNA strand template

28
Q

DNA is read from

A

3’ to 5’

29
Q

DNA is created from

A

5’ to 3’

30
Q

In elongation what does the RNA polymerse travel down

A

DNA template

31
Q

With what are RNA strands created with

A

bases complimentary to DNA strand

32
Q

Why do the RNA strands separate

A

so DNA strands can reattach

33
Q

at termination signal what does the polymerse release

A

DNA and RNA

34
Q

What RNA strand is created at the end of transcription

A

messenger RNA (mRNA)

35
Q

What is the full name of RNA

A

ribionucleic acid

36
Q

What are the three types of RNA

A

Messenger, ribosomal, and transfer

37
Q

What do the messenger RNA do

A

code for protein

38
Q

What do the ribosomal RNA do

A

protein complex that reads mRNA and builds protein

39
Q

What do the transfer RNA do

A

caries specific amino acids

40
Q

What is the translation RNA made of

A

protein

41
Q

What does the mRNA do in translation

A

carries code from nucleus to cytoplasm

42
Q

What couples with mRNA in translation

A

ribosomes

43
Q

what do the tRNA do in translation

A

bring in appropriate amino acids
