Answer:
Cas9-sgRNA cannot align with targeted DNA sequence
Explanation:
Without a PAM sequence, the CRISPR-sgRNA (small guide RNA) complex cannot align with the targeted DNA sequence. Therefore, you cannot perform experiments (e.g. gene editing) using CRISPR-Cas9.
Metamorphic rocks are formed from existing rocks, when it is exposed to great heat and pressure. This process would destroy any fossils inside the already existing rock.

Answer:
a. Yeast, nematodes and brine shrimp use the same means to survive desiccation.
Explanation:
5. Adenine and thymine base pair
6. Chargaff's base ratios
10. Hydrogen bonds exist between base pairs (A/T and G/C) allowing DNA to maintain the helical structure. Adenines and thymines have two hydrogen bonds, guanines and cytosines have three. When these hydrogen bonds are broken, this allows for "unzipping" of the DNA - which can then be replicated, transcribed/translated to RNA, etc.
