Replication Of DNA

Question 1

Describe the process of DNA replication

Answer 1

• an enzyme unzips the DNA molecule, exposing the nitrogen base codes(a g c t)
• exposed strands then act as a template or pattern for the construction of a new molecule
• DNA polymerase works its way along the unzipped molecule, and adds new nucleotides to the exposed ones(a:t g:c)

Question 2

Describe the process of transcription

Answer 2

• DAN unwinds at relevant section
• mRNA nucleotides combine to construct a complementary strand
• RNA polymerase AIDS this process and only one strand of DAN is copied

Question 3

Describe the process of translation

Answer 3

• mRNA travels out of nucleus into cytosol and to ribosomes
• each anticodon on tRNA base codes for one amino acid
• tRNA with attached amino acid travels to mitochondria
• tRNA anticodon attaches to mRNA codon
• each amino acid is joined to the next base on codon sequence
• continues until the correct number of amino acids are produced, than released as proteins

Question 4

Transcription and translation are the two stages of what process?

Answer 4

Protein synthesis

Question 5

What is DNA replication?

Answer 5

The process that creates a new identical DNA molecule
