Q
Does each strand or DNA has all the info needed to construct the other half?
A
Yes
8
Q
Replication steps
A
- Hydrogenbonds between nucleotides break
- DNA seporates
- New nucleotides are added onto the strands that have been seporated

13
Q
Transfer RNA (t-RNA)
A

14
Q
Ribosomal RNA (rRNA)
A
combines amino acids together to form ribosomes

Q
Transcription
A
RNA polymerase separates strands, then uses one strand as a template to resemble RNA
