Nucleotide

• RNA

• Large chain amino acids

• • building blocks of nucleic Acids.

• X-Ray

Base pairing

• bonds in DNA can form only between adenine and thymine and between guanine and cytosine.

• AUG

• MRNA

• Amino Acids

Double helix

• Amino Acids

• • 2 strands of nucleotides separated around each other.

• 3 base paring

• 3 strands of nucleotides separated around each other.

Antiparallel

• It is complementary

• • 2 strands of DNA run in opposite directions.

• 2 strands of DNA run the same directions.

• It is replicated.

Complementary strands

• Run the same directions.

• Amino acids

• Run in the opposite directions.

• Building blocks of protein.

Replication

• It is a copy of DNA.

• it has 4 base pairing.

• AUG

• process of copying DNA prior to cell division.

Replication fork

• DNA

• Amino Acids

• area where new bases are added, where replication actually takes place.

• Makes Protein.

DNA helicase

• • separates/unzips the 2 strands of DNA’s double helix, forms replication forks.

• Large chain amino acids

• The replication of RNA

• Transmittion.

DNA polymerase?

• Joins individual amino acids to produce a copy of DNA.

• Is the translation of chromosomes.

• There is 1 new and one copy of the original.

•  joins individual nucleotides to produce a new strand of DNA, also proofreads each new DNA strand.
