- DNA structure/replication & protein synthesis

Question 1

Name the different types of Nucleic acid that makes up DNA

Answer 1

Guanine,Thymine, Cytosine, and Andenine

Question 2

What makes Guanine, Thymine, Cytosine and Andeine the same

Answer 2

The Phosphate and the sugar

Question 3

What types of bonds hold the DNA model together

Answer 3

Weak hydrogen bonds to the pairs an Strong covalent bonds bond to the Sugar and Phosphate

Question 4

How can you tell DNA is Anti-parallel

Answer 4

You can tell when the strands go in opposite directions

Question 5

Can you determine the direction of each side

Answer 5

Whatever side your sugar is on that’s your 5 prime side

Question 6

What patterns show up in DNA

Answer 6

G and T are on opposite sides and A and C are upside down

Question 7

What is different between RNA and DNA

Answer 7

RNA is a single strand while DNA is a double strand

Question 8

Purpose of DNA

Answer 8

It holds our genetic material and it is the blue print for proteins

Question 9

What direction does DNA Polymarse only travel in

Answer 9

Going 3 prime to 5 prime to build a 5 prime to 3 prime strand

Question 10

What are the fragments called on two lagging strands

Answer 10

Okazaki Fragments

Question 11

What is the result of DNA replication

Answer 11

Two identical DNA molecules are formed

Question 12

Why is DNA replication nesscary

Answer 12

Replicationg so that cells can have the same DNA from the cell its coming from

Question 13

Why is DNA Replication said to be semi-conservative

Answer 13

It is semi-conservative because one of the strand of DNA is conserved while the other is newly produced

Question 14

What would the chromosomes to the right look like after DNA Replication

Answer 14

A sister Chromtaid

Question 15

DNA Replication process

Answer 15

The Enzyme Helicase unzips the DNA into two strands
DNA Polymarse helps find complementary bases and bind according to base-pairing rules
Two identical DNA molecules are formed each with and “old” strand a new strand

Question 16

What is Central Dogma

Answer 16

The Flow of genetic info DNA goes to transcription to RNA translation to protein

Question 17

mRNA

Answer 17

Copies instructions in DNA and carries these to the ribosome in the cytoplasm

Question 18

tRNA

Answer 18

binds and carries specific amino Acids to the ribosome

Question 19

rRNA

Answer 19

along with proteins it makes up ribosomes

Question 20

In what process is mRNA synthesized

Answer 20

Transcription

Question 21

What is a codon?

Answer 21

A set of three nucleotides which form a code for amino acids

Question 22

What is the purpose for anti-codon

Answer 22

To base pair with the codon to bring the correct Amino acids that are being drooped off

Question 23

What is a polypeptide a sequence of?

Answer 23

Chains of amino acids and its boned by peptide bonds

Question 24

What two things does tRNA transfers or carry to the ribosome

Answer 24

Amino acids and anti-codons

Question 25

In what two places in the cell can translation occur

Answer 25

The cytoplasm and the rough ER

Question 26

Where does translation occur

Answer 26

It occurs in the nucleus because that's where DNA is so it must happen there

Question 27

How many codons equal 1 amino acid

Answer 27

1

Question 28

How many nucleotides equal 1 amino acids

Answer 28

3

Question 29

What is an anti-codon where is it located

Answer 29

Complementary 3 nucleotides located on t RNA
