The fluid mosaic model accounts for the presence of protein in the cell membrane by proposing that:

The fluid mosaic model was proposed by the Singer and Nicolson in 1972 which stated that the plasma membrane is composed primarily of phospholipids with other molecules like cholesterol, glycolipids and proteins.

Due to the presence of these molecules, the plasma membrane appears like a mosaic of molecules in which the proteins are either present in the embedded in the plasma membrane called " integral proteins" or proteins are attached at the surface known as " peripheral proteins".

Thus, the Fluid mosaic model comprises of the proteins also which forms the second major component of the plasma membrane.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
