6. Adenine pairs with thymine, there are 2 hydrogen bonds between them.

7. Guanine pairs with cytosine, there are 3 hydrogen bonds between them.

8. The 2 bases that are purines are : adenine and guanine

9. The 2 bases that are pyrimidines are : thymine and cytosine

10. Purines can’t bond with purines and pyrimidines can’t bond with pyrimidines because there is not enough space for two purines to fit within the helix and too much space for two pyrimidines to get close enough together for hydrogen bonds to form between them.

making a claim is just a fancy way of saying that you're stating your main point.' claims are not just opinions. a claim tells what you think is true about a topic based on your knowledge .

about the country claims : -

a counterclaim is just the opposite of a claim. counterclaims are also provable and supportable by reasons and evidence. not just, 'because i said so.' when you're planning an argument, you need to know what the counterclaim might be so that you can make sure that you disprove it with your reasons and evidence your research." - (catherineroberts)
