Answer 2

A U G G G C U G G U A A

Question 3

Nucleotides

Answer 3

the building blocks of DNA

Question 4

Chromosome

Answer 4

made up of genes

Question 5

Gene

Answer 5

a section of a DNA molecule that contains the instructions for a specific protein

Question 6

Answer 6

organic molecule that contains the instructions for all living things

Question 7

Each tRNA attaches to a specific ______

Answer 7

amino acid

Question 8

Transcription
where does it occur

Answer 8

nucleus

Question 9

Translation
where does it occur

Answer 9

cytoplasm

Question 10

What is the end result of transcription?

Answer 10

RNA

Question 11

tRNA

Answer 11

Ribosomes would not have the amino acids they need to synthesize proteins

Question 12

rRNA

Answer 12

Ribosomes would be missing a part and would not be able to synthesize proteins

Question 13

mRNA

Answer 13

Genes’ instructions would not be able to leave the nucleus, so ribosomes would not have a blueprint they need to synthesis proteins

Question 14

Place the steps of DNA replication in order from beginning to end.

Answer 14

The DNA helix untwists
Enzymes separate the 2 DNA stand
The new nucleotides are added by enzymes
2 identical DNA molecules are produced

Question 15

Is the following strand a strand of DNA or RNA? How do you know? AUGGAU

Answer 15

RNA because only RNA has U’s

Question 16

which of the following bases is not found in RNA

Answer 16

Question 17

Translation

Answer 17

uses the mRNA code to create a protein in the ribosomes found in the cytoplasm

Question 18

Replication

Answer 18

the creation of 2 sets of DNA for cell division. Unwinding and adding in new nucleotides

Question 19

Transcription

Answer 19

using DNA as a template to create an mRNA code, which occurs in the nucleus

Question 20

tRNA contains a three nucleotide part called a

Answer 20

Anticodon

Question 21
