T3 Lesson 11 - Transcription and translation

Question 1

DNA

Answer 1

molecule that controls who you are - it is a nucleic acid

Question 2

Genome

Answer 2

The entire DNA of an organism

Question 3

gene

Answer 3

Section of the DNA molecule that codes for a specific protein

Question 4

Nucleus

Answer 4

Holds DNA that is wrapped into chromosomes

Question 5

DNA structure

Answer 5

• 2 strands joined in a twisted ladder called a double helix
• 4 DNA bases - adenine, thymine, guanine & cytosine
• Each step of the ladder has a pair of DNA bases - Adenine & Thymine (AT) -Guanine & Cytosine (CG)

Question 6

What is RNA

Answer 6

• nucleic acid
• it is single stranded
• has 4 strands - Adenine, Guanine, Cytosine, Uracil

Question 7

What is the difference between DNA and RNA?

Answer 7

RNA is single stranded
The Thymine strand is replaced with the Uracil strand

Question 8

Number of chromosomes in a human body cell

Answer 8

46 - 2 of each (23 pairs)

Question 9

what is a deploid cell?

Answer 9

a cell that contains 46 chromosomes

Question 10

Base pairings in DNA?

Answer 10

(A-T) Adenine to Thymine,
(G-C) Guanine to cytosine

Question 11

Number of chromosomes in gamete (also known as a haploid cell)

Answer 11

23

we get 23 from each parent which then makes 46 chromosomes altogether (Deploid)

Question 12

Number of chromosomes in gamete?

Fill in the blanks

Answer 12

Question 13

Chromosome

Answer 13

The structures that contain DNA
