Answer:
Option D (4), add phosphate groups
Explanation:
Kinase enzymes are responsible for cellular activation. Protein kinase causes phosphorylation of specific amino acids by utilizing ATP as source of phosphate.
It adds phosphate groups (PO43−) and induces biological activity of biomolecules (such as proteins, lipids, and nucleic acids) by changing their conformation thereby activating them .
Human genome consists of several hundreds of kinase encoding genes which are involved in multiple phosphorylation reactions with in the cytoplasm of cells.
Hence, Option D (4) is correct
Answer:
the answer is C
Explanation:
Stomata are pores localized in the plant epidermis whose function is to regulate gas exchange between plants and the atmosphere. Generally, stomata open during the day to allow the diffusion of carbon dioxide (CO2) and close during the night to avoid water loss (i.e., transpiration). On the other hand, CAM plants photosynthesize during the day, and exchange gases (CO2 and O2) during the night. Thus, desert CAM plants open their stomata during the night and close them during the day hours. These desert plants open stomata at night to absorb CO2 and close them during sunlight hours to prevent transpiration.

Answer:
The mutations lie at locations where they don't affect protein sequence due to degeneracy of the genetic code.
Explanation:
Genetic code is the set of the triplet codons each of which code for a specific amino acid. The nucleotide sequence of mRNA is read in the form of triplets during the process of protein synthesis and the respective amino acid is added to the growing polypeptide chain. The genetic code is degenerate. This means that more than one triplet code specifies one amino acid and some amino acids are encoded by more than one codon.
For instance, genetic codes CUU, CUC, CUA, CUG specify amino acid "leucine". Therefore, any change in the DNA sequence that replaces one code for the leucine with another would not affect the amino acid composition of the protein. This would result in the synthesis of proteins with the same amino acid sequence from both the wild type and mutated genes.
