Sandra excels in reading and spelling but struggles with mathematics. she is shorter than her peers and has a webbed neck. her doctor has determined that she has one x chromosome missing. sandra most likely has:

The correct answer is - turner syndrome.

Explanation:

Turner syndrome is is a chromosomal condition are due to the missing or partially missing one sex chromosome in females. It is specific to females only. It leads to different types of problems such as short stature, ovarian hypofunction, infertility, delayed puberty, webbed neck, learning disabilities, and many other symptoms.

As Sandra has short stature, the problem in the learning and doctor also determined that she has one X chromosome missing so it can be determined by that she has turner syndrome.

Thus, the correct answer is - turner syndrome.

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.
