(protein)?
belka [17]

Answer:

Since, the original DNA sequence has not been provided, the mutation can be an insertion/deletion or a frameshift mutation.

  1. Mutated DNA
  2. Frameshift mutation/ insertion or deletion
  3. All the amino acids  changed after the  point mutation​

Explanation:

Frameshift Mutation:

  • A frameshift mutation is the alteration in the reading frame of the DNA due to the addition/deletion of one or two nucleotides.
  • This type of mutation moves the mRNA sequence one or two bases forwards or backwards which disrupts the three base codons sequence required for translation into proteins.
  • The CT at the end of the sequence is indicative of a frameshift in the DNA reading frame.
  • Frameshift mutation affect all amino acids in a polypeptide chain as all codons are moved one or two steps forwards or backwards.

Which of the following is necessary for the light-independent reactions to proceed?
Yanka [14]

Answer;

C) ATP

Explanation;

-Photosynthesis can be divided into two parts: the light-dependent reactions and the light-independent reactions (also referred to as the "dark" reactions).

-The two products of the light-dependent reactions of photosystem are ATP and NADPH.  The movement of high energy electrons releases the free energy that is needed to produce these molecules.  The ATP and NADPH are used in the light-independent reactions to make sugar.

-The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
