It is possible to convert the Cys that is a part of Cys-tRNACys to Ala by a catalytic reduction.  If the resulting Ala-tRNACys were added to a mixture of (1) ribosomes, (2) all the other tRNAs and amino acids, (3) all of the cofactors and enzymes needed to make protein in vitro, and (4) mRNA for hemoglobin, where in the newly synthesized hemoglobin would the Ala from Ala-tRNACys be incorporated?

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 Becker muscular dystrophy?

Light-response curves of photosynthetic carbon fixation in sun and shade plants. Typically, shade plants have a low light compensation point and have lower maximum photosynthetic rates than sun plants this is because respiration rates in shade plants are very low; which of the following graph is correct?
