Function of DNA

Carry genetic information

1

3 parts of a nucleotide

5 carbon sugar-deoxyribose
Phosphate group
Nitrogen base-one of four

2

Four nitrogen bases

Adenine
Thymine
Guanine
Cytosine

3

Base pairing rules

A-T
C-G

4

DNA replication

Process of making new copies of DNA

5

Steps of DNA replication

-DNA untwists
-DNA helicase unzips the DNA
-new nitrogen bases attach to the unzipped DNA

6

DNA template

Strand of DNA which will be used to transcribe the mRNA for protein synthesis

7

Helicase

An enzyme that unzips DNA or RNA

8

DNA polymerase

Those of enzyme that is responsible for forming new copies of DNA in the form of nucleic acid molecules

9

Function of RNA

Help carry out DNA's blueprint guidelines. Transfers genetic code needed for the creation of proteins from the nucleus to the ribosome

10

Compare DNA and RNA

DNA is double stranded
RNA is single stranded

11

Where does transcription occur

The nucleus

12

What is transcription

When a segment of DNA is copied on to mRNA so it can leave to nucleus

13

Parts of RNA nucleotide

5 carbon ribose sugar
Phosphate group
One of four nitrogen bases

14

RNA's nitrogen bases

Adenine-uracil
Cytosine-guanine

15

3 types of RNA

Messenger
Transfer
Ribosomal

16

mRNA function

Carries code from DNA to the ribosome

17

tRNA function

Used for picking up amino acids

18

rRNA function

Major component of ribosomes

19

The nucleotide triplets of DNA and RNA molecules that carry genetic information in living cells

Genetic code

20

Sequence of 3 nucleotides that together form a unit of genetic code in DNA or RNA molecule

Codon
