Which one of the following statements related to photosynthesis is NOT correct?

#Unit 6. System Physiology – Plant

The light and carbon reactions of photosynthesis occur in separate chloroplast compartments
Light is required for the synthesis of ATP and NADPH substrates in a series of reactions that occur in thylakoid membranes of the chloroplast.
Light is required for the synthesis of ATP and NADPH substrates in a series of reactions that occur in stroma of the chloroplast
The photosynthetic electron transport chain moves electrons from water in the thylakoid lumen to soluble redox‐active compounds in the stroma

#Unit 8. Inheritance Biology

In this pedigree I 1 and II 2 have Becker muscular dystrophy which shows X-linked recessive inheritance. III 2 has oculocutaneous albinism which shows autosomal recessive inheritance with an incidence in the general population of 1 in 10 000. The disease status for both Becker muscular dystrophy and oculocutaneous albinism is unknown for IV 1 and IV 2.

What is the probability that IV 2 will be affected with oculocutaneous albinism?

A panel of cell lines was created by human—mouse somatic-cell hybridization. Each cell line was examined for the presence of human chromosomes and for the production of three enzymes. The following results were obtained:

On the basis of these results, give the chromosomal locations of the genes encoding enzyme 1, enzyme 2, and enzyme 3.

The following is a schematic representation of region of the chromosome of fly along with extent of six deletions (Del 1 to Del 6);

When flies homozygous for the recessive mutations are crossed with flies heterozygous for the deletions, the following results are obtained, in which "m" represents a mutant phenotype and a plus sign (+) represents the wild type. On the basis of these data, determine the relative order of the seven mutant eenes on the chromosome.
