DNA

Question 1

alleles

Answer 1

trait/feature of an organism

Question 2

messenger RNA (mRNA)

Answer 2

template for protein synthesis, end of transcription

Question 3

transfer RNA (tRNA)

Answer 3

translates mRNA sequence to make into amino acid

Question 4

ribosomal RNA (rRNA)

Answer 4

part of the ribosome

Question 5

RNA polymerase

Answer 5

unwinds DNA so it can be read and copy is made

Question 6

termination signal

Answer 6

stopping point for RNA polymerase reading

Question 7

transcription

Answer 7

building copy of read DNA strand

Question 8

translation

Answer 8

RNA sequence made into amino acids

Question 9

genetic code

Answer 9

amino acids, made in codons (3 nucleotides at a time)

Question 10

start codon

Answer 10

AUG, start reading here

Question 11

stop codons

Answer 11

UAG, UAA, and UGA, stop reading

Question 12

point mutations

Answer 12

a single nucleotide changes (silent=nothing, missense=change,nonsense=stop codon)

Question 13

chromosomal aberration

Answer 13

deletion, relocation, duplication of entire sections in chromosome

Question 14

DNA helicase

Answer 14

unwinds the DNA for DNA synthesis
