DNA structure, replication, protein synthesis and mutations REVIEW

Mrs. Dallimore
Biology
Across
Chargaff's rule says that if there is approximately twenty percent Thymine there will be approximately ____ Guanine.
Sugar found in RNA
Double stranded Nucleic Acid with the bases A, T, C, G
Enzyme that opens DNA during replication
Makes up the backbone of the DNA molecule: _____ and phosphate.
Complementary DNA strand to: AGC CAT GTA TAC
Always bonds with Cytosine
Always bonds with Thymine in DNA
In DNA replication, each strand is a template for a new strand so that the result is two DNA molecules each with one old strand and one new strand.
Three base sequence on the tRNA
One base is added and the other bases shift to the right
Sugar found in DNA
Down
One base is changed
Only found in DNA, bonds with Adenine
Type of substitution that leads to no change in the amino acid sequence.
Always bonds with Guanine
Takes place in the ribosome; mRNA goes to the ribosome where tRNA brings an amino acid and the polypeptide chain begins to form
Only found in RNA, bonds with Adenine
Change in the DNA code
Takes place in the nucleus; mRNA is made as the DNA code is copied.
One base is deleted and the other bases shift to the left
Three base sequence on the mRNA
