Quiz # 4 second sem

Question 1

transcription

Answer 1

converting genetic code in DNA to mRNA

Question 2

translation

Answer 2

converting the genetic code of mRNA into a sequence of amino acids and ultimately a protein

Question 3

codon

Answer 3

three letter sequence on mRNA that codes for a specific amino acid

Question 4

what are the steps of transcription

Answer 4

initiation, elongation, termination

Question 5

what is initiation

Answer 5

RNA polymerase links to a promoter… region that recognizes start of gene (TATA box)

Question 6

what is elongation

Answer 6

RNA nucleotides are linked together flailing off as it synthesized

Question 7

what is termination?

Answer 7

RNA reaches a sequence of bases that signals the end of the gene (C and G rich that causes mRNA to start pairing with itself)

Question 8

what does mRNA do?

Answer 8

used to encode amino acid sequences form DNA

Question 9

what does tRNA do?

Answer 9

transfers/delivers amino acids to the ribosome where proteins are made
