In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. ... The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH.
If the paramecium was not able to contract its contractile vacuole, it would be in danger of bursting. The cell would not be able to hold too much water. This would happen faster if the paramecium was in water with a low salt concentration because there is more water and less salt, so the water would accumulate faster.
- TGA (opal)
Answer:
Explained below
Explanation:
A mutation in a gene that results in total loss of the normal function of the gene product encoded by that gene, resulting in a Null phenotype.
Changes in DNA sequence are termed as nonsense mutation that introduce a stop codon, resulting in a non functional protein. This terminology results stop codons have also worked as nonsense codons.
There are three different stop codon-
In RNA
- UAG (amber)
- UAA (ochre)
- UGA (opal)
In DNA
- TAG (amber)
- TAA (ochre)
- TGA (opal)
