Answer:
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is too 'unzip' the double helix structure of the DNA? molecule.
Explanation:
Secondary structure is created when a polypeptide chain folds as a result of a contact between the carbonyl group and the peptide linkage's N-H group. The given statement is True.
These proteins have the ability to fold themselves, thus their amino acid sequences must have all the necessary information. Peptide bonds are created when amino acids condense to form protein structures. The main structure of a protein is its arrangement of amino acids.
The dihedral angles of the peptide bonds determine the secondary structure, while the folding of protein chains in space determines the tertiary structure.
A peptide bond is a covalent connection that occurs when an amino acid's α-amino group and carboxyl group are joined together without the need of water.

The answer is taiga.
Taiga is a coniferous forest located in the northern polar subarctic climate zone. What is characteristic for taiga is that winters are very long and very cold. Summers are, on the other hand, short with low temperatures. Many trees in the forest are evergreen conifers with needle-like leaves. <span>Animals have adaptations to seasonal changes by changing their fur or feather color. <span /></span>
Answer:
The scientist done wrong by inactivating chlorophyll A and PS I.
Explanation:
The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.
