Question 1

What is DNA?

What are the letters used to represent it?

Answer 1

DNA is a string of coded information that lies in the nucleus of the cell.

The letters used are C, G, T, A

Question 2

Translate the following DNA sequence into its letter match;

C G C A T

Answer 2

G C G T A

Question 3

Translate the following DNA sequence into RNA

A G T C G

Answer 3

U C A G C

The U was originally a T (matched by an A). But since there is no T in RNA language, a U is used instead.

Question 4

Explain the types of matched DNA hydrogen bonds

Answer 4

G to C (C to G) Triple Bonded

A to T (T to A) Double Bonded

C to G (G to C) Triple Bonded

T to A (A to T) Double Bonded

Question 5

Explain the diagram of how to represent the info that DNA carries

Answer 5

Pentagons are used to represent the DNA letters and two letters are matched to the corresponding with the connecting hydrogen bonds.

Then on the sides of the pentagon DNA letters (deoxyriboses aka sugars) are zig zag phosphates.

Question 6

Explain the steps for hereditary to happen.

Answer 6

DNA turns into m(messenger) RNA by transcription →

by translation, mRNA turns into proteins →

which then turns into enzyme structure trait
