densk [106]

Answer:

The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.

One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.

A frameshift mutation that occurs very early in a protein sequence would have what effect on the protein's structure? A. The pri
AlekseyPX

Answer:

C. Primary, secondary, and tertiary structures would be altered

Explanation:

Frameshift mutations refer to the mutations that change the reading frame of the gene. Frameshift mutations are mostly caused by insertion or deletion of nucleotide since addition or loss of nucleotide alters all the codons present downstream of the point of the mutation site. If frameshift mutation occurs at the beginning of the protein sequence, all the downstream amino acids would be altered.

The changed amino acid sequence would alter the primary structure of the protein. Since the secondary and tertiary structure of proteins is determined by interactions between the R groups of amino acids, their polarity, charge, etc., the altered amino acid sequence would also alter secondary, and tertiary of the protein.
