Is the number of adenine bases same as thymine bases on the same strand
NOOOO.
The percentages of bases on one strand don’t have to be the same (e.g. A ≠ T on the same strand).
But across both complementary strands, base pairing rules apply:
Adenine (A) pairs with Thymine (T)
Cytosine (C) pairs with Guanine (G)
Complete the table
.
Have different genes;
Reject: different alleles
2. 3. (Sobases / triplets) are in a different sequence / order;
Accept: base sequence that matters, not percentage
(So) different amino acid (sequence / coded for) / different protein /
different polypeptide / different enzyme.
A does not equal T / G does not equal C;
Accept: similar for equal
Accept: virus has more C than G / has more A than T
2. (So) no base pairing;
- (So) DNA is not double stranded / is single stranded.
DNA has antiparallel strands ;
(Figure 1 shows) shape of the nucleotides is different / nucleotides aligned differently;
Enzymes have active sites with specific shape;
Only substrates with complementary shape / only the 3’ end can bind with active site of enzyme / active site of DNA polymerase./
What is D on the diagram
