Q

What shape is DNA?

A

A double helix

1
Q

What are the complementary base pairs for DNA?

A

AT

GC

2
Q

What does DNA do?

A

It carries the genetic code

3
Q

What are the building blocks of DNA?

A

Nucleotides

4
Q

What is a nucleotide made up of?

A

A phosphate group
A (deoxyribose) sugar
A nitrogenous base

5
Q

Where is DNA located?

A

In the nucleus

6
Q

What is the site of protein synthesis?

A

The endoplasmic reticulum/ ribosomes

7
Q

Name the 4 DNA bases

A

Adenine
Thymine
Guanine
Cytosine

8
Q

Name the 4 mRNA bases

A

Adenine
Uracil
Guanine
Cytosine

9
Q

What are the complementary base pairs for mRNA?

A

AU

GC

10
Q

Why do we need mRNA?

A

To make a copy of the code and travel to the ribosomes as DNA is too big to get out of the nucleus

11
Q

What is transcription?

A

When the code on the DNA is copied in the nucleus

12
Q

What is translation?

A

The amino acids match up with the bases then form a chain of protein

13
Q

What is a triplet of bases called?

A

A codon

14
Q

Where does translation take place?

A

In the cytoplasm at the ribosome

15
Q

What does tRNA do?

A

It brings the matching amino acids with the other half of the code to the mRNA codons during translation
