A-Adenine
T-Thymine
G-Guanine
C-Ctyosine

42
Q

DNA is _____ nucleotide pairs long

43
Q

Gene

A

are on your DNA and contain info to make protein

44
Q

Another name for protein synthesis

A

Gene expression

45
Q

Genes will turn on and off based on the ________ around

46
Q

What are the two steps of Protein synthesis in order

A
  1. Transcription
  2. Translation
47
Q

Transcription

A

When one gene is copied into m-RNA and happens in the nucleus

48
Q

Translation

A

When the m-RNA is read by the t-RNA to assemble a protein at the ribosome in cytoplasm. t-RNA leaves the anti codon with the codon and gets another amino acid this cycle repeats for amino acids to build up.
