How many types of nucleic acids do we have in our body?

1.)What does RNA do?

2.)Where does it get its code from?

1.)makes proteins

2.)from DNA

Phosphate, 5 carbon sugar, and a nitrogen base.

1.)Both have adenine

2.)Both have cytosine

3.)Both have guanine

     4.)Both have nucleotides 

1.)DNA has deoxiribose, RNA has ribose for sugar

2.)DNA has Thymine, RNA has Uracil

3.)DNA is double stranded, RNA is single stranded

A pairs with T and C pairs with G in DNA.

A pairs with U and C with G in RNA.

_______ break the __ bond between the DNA.

1.)Enzymes

2.)H+ OR Hydrogen

Why do DNA have weak bonds such as a Hydrogen bond?

1.)What are the chances of replication not being accurate?

2.)What happens if replication isn't accurate?

1.)10^-8to 10^-12

2.)Gene mutation occurs

Replication begins at ________ origins on the DNA strands.

1.)An enzyme breaks the Hydrogen Bonds.

2.)2 strands unwind and act as a template.

3.)DNA nucleotides pair up with the templates by Complimentary Base Pairing.

4.)DNA Polymerase acts as a glue and proofreader.

5.)New Hydrogen bonds form.

1.)RNA polymerase connects to a promoter on DNA

2.)Hydrogen bonds break

3.)RNA nucleotides do complimentary base pairing

4.)Stop Code is reached

5.)New mRNA is formed.

6.)mRNA leaves the nucleus and travels to ribosomes

7.)Old DNA strands form hydrogen bonds

1.)AA are carried to mRNA by a tRNA.

2.)the anticodon on the tRNA pairs with the codon on the mRNA.

3.)The AA's connect together forming the specific protein.

4.)tRNA leaves to pick up another AA.
