You can just ask a question and we can help what do you need help u
So there are four types of nucleotides in DNA:
- Adenine
- Cytosine
- Guanine
- Thymine
And the complements are:
- Adenine ⇄ Thymine
- Cytosine ⇄ Guanine
<u>Using this information, the complementary base of TTGCACG is AACGTGC.</u>

Are there any answer choices to choose from?
A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells
