#1
Front (Question)

What are the 3 components that make up a nucleotide?

Back (Answer)

• pentose sugar • phosphate group • nitrogenous base

#2
Front (Question)

DNA acts as a template to make RNA in a process known as ______?

Back (Answer)

Transcription * which takes place in the nucleus

#3
Front (Question)

RNA acts as a template to make protein in a process known as ______?

Back (Answer)

Translation * which happens in the cytoplasm on ribosomes

#4
Front (Question)

Purines are made up of ___ ring(s)

Back (Answer)

2

#5
Front (Question)

Pyrimidines are made up of ____ ring(s)

Back (Answer)

1

#6
Front (Question)

A forms ___ H bonds with T C forms ___ H bonds with G

Back (Answer)

A forms 2 bonds with T C forms 3 bonds with G

#7
Front (Question)

Purines : Pyrimidines:

Back (Answer)

A and G are purines C and T are pyrimidines

#8
Front (Question)

Where do phosphodiester bonds form ?

Back (Answer)

Between the pentose sugar and the phosphate group

#9
Front (Question)

Why don’t RNA have H bonds?

Back (Answer)

Because single-stranded. Only have phosphodiester in sugar-phosphate backbone. No need to hold 2 nitrogenous bases tgt

#10
Front (Question)

How to break down polynucleotides

Back (Answer)

Hydrolysis (+ water)

#11
Front (Question)

How to form polynucleotides from nucleotides?

Back (Answer)

Condensation polymerisation/ dehydration synthesis (- water)

#12
Front (Question)

Function of helicase

Back (Answer)

Convert double stranded DNA into single-stranded DNA by breaking hydrogen bonds

#13
Front (Question)

Function of single-stranded binding protein

Back (Answer)

To bind on single strands of DNA and prevent them from reannealing

#14
Front (Question)

Function of primase

Back (Answer)

To create RNA primers based on template strand

#15
Front (Question)

Function of DNA polymerase III

Back (Answer)

To add complimentary DNA nucleotides to the 3’ end, based on the template

#16
Front (Question)

Function of sliding clamp

Back (Answer)

To move DNA polymerase III along the template strand

#17
Front (Question)

Function of nuclease

Back (Answer)

To remove RNA primers

#18
Front (Question)

Function of DNA polymerase I

Back (Answer)

To replace RNA nucleotides with DNA nucleotides

#19
Front (Question)

Function of DNA ligase

Back (Answer)

To join the replicated DNA fragments into a single continuous strand

#20

Other types of monohybrid inheritance

Back (Answer)

• Incomplete dominance • Co dominance • Multiple alleles

#21
Front (Question)

What do multiple alleles mean?

Back (Answer)

When one gene has more than two alleles

#22
Front (Question)

3 exceptions to Mendels law

Back (Answer)

• Polygenic inheritance • Linked genes • Effect of environment

Back (Answer)

Interphase - G1, S & G2

#24
Front (Question)

What happens after Prophase?

Back (Answer)

Metaphase
