Crossword 2

Question 1

rRNA

Answer 1

Type of RNA used in the ribosome during protein synthesis

Question 2

Inversion

Answer 2

Chromosomal mutation where piece of chromosome is “flipped”

Question 3

Protein

Answer 3

Made up of chains of amino acids strung together

Question 4

mRNA

Answer 4

Type of RNA brings the instructions from the DNA molecule to ribosome

Question 5

Polymer

Answer 9

Affects only 1 gene

Question 10

Viral mutagen

Answer 10

Question 11

Addition

Answer 11

Gene mutation where a nucleotide is inserted into a gene

Question 12

Translocation

Answer 12

Chromosomal mutation where a piece of one chromosome is transferred to another chromosome

Question 13

Uracil

Answer 13

Nitrogenous base in RNA not DNA

Question 14

Pyramidine

Answer 14

Nitrogenous base with single ring structure

Question 15

Golgi apparatus

Answer 15

Completed proteins sent here for final processing and packaging

Question 16

Chemical mutagens

Answer 16

Benzene

Dioxins

Question 17

Duplication

Answer 17

Chromosomal mutation where portion of a chromosome repeats itself

Question 18

Carcinogen

Answer 18

Mutagen that causes cancer

Question 19

Germinal mutations

Answer 19

Occur in gametes or early embryo development

Question 20

Peptide bonds

Answer 20

Form between adjoining amino acids

Question 22

Complimentary base pairing

Answer 22

A-T

C-G

Question 23

Release factor

Answer 23

Enters the ribosome to signal a stop codon, then amino acid chain is released from ribosome

Question 24

Plasmid

Answer 24

Small, circular piece of DNA used to transfer DNA from 1 species to another species

Question 25

Chromosomal mutation

Answer 25

Affects many genes because large portions of chromosomes are altered

Question 26

Frame shift

Answer 26

When all codons downstream are altered during addition/deletion (devastating)

Question 27

DNA polymerase

Answer 27

Enzyme that adds new DNA nucleotides to the growing strand during replication

Question 28

Elongation

Answer 28

Second phase of translation where amino acid chain grows

Question 29

Covalent bonds

Answer 29

Strong

Form between the sugar and phosphates to form backbone of molecule

Question 30

Codon

Answer 30

3 letter sequence on mRNA that codes for an amino acid

Question 31
