DNA

Question 1

Chromosome

Answer 1

Prednisones are long molecules of coiled up DNA

Question 2

Double helix

Answer 2

Each of the two DNA strands is made up of lots of small groups called nucleotides

Question 3

nucleotide

Answer 3

Each one contains a molecule called a base DNA has just four different baces

Question 4

baces

Answer 4

You only need to know the four bases by the first initials a C G and T

Question 5

Cross links

Answer 5

Each base forms cross links to a base on the other strand this keeps it to DNA strands tightly well together

Question 6

Which bases parer up with which basis

Answer 6

A always pays up with T and c always pays up with G this is called a complimentary base-pairing

Question 7

DNA division

Answer 7

DNA copies itself every time a cell divides so that each new cell still has full amount of the DNA

In order to copy itself the DNAs double helix must first unzip to form to single-strand
new nucletidos
The result is to double-stranded molecules of DNA that are identical to the original molecule of DNA
