Q

What do used to read mRNA

A

TRNA

17
Q

What reads mRNA codon

A

Anticodon loop

18
Q

The ribosome has 2

A

Subunits one large and one small which is made from proteins and RRNA

19
Q

Steps to control gene expression

A

Stop making mRNA
Stop splicing process
Stop transport of mRNA

20
Q

MiRNA

A

Non coding RNAs
50% are processed from introns
Short

21
Q

MiRNA cause

A

Transcriptional repression by degrading mRNA targets, as they bind to target mRNA complimentary to break down, this helps control gene expression

22
Q

Loss of MiRNA causes

A

Loss of transcriptional control and cancer

23
Q

What acts as a switch for transcription

A

Phosphorylation of RNA polymerase

24
Q

MRNA is read in groups of

A

Three bases or codons which make up the reading frame

25
Q

Each codon encodes a particular

A

Amino acid
