The planets that reside in the region of the solar system are jupiter , uranus, and neptune. although these planets are made up of lighter elements, they have a solid core. the atmosphere of all these planets is made up of hydrogen and . in addition to these two elements, the planets neptune and contain methane.

The planets that reside in the Outer region of the solar system are Jupiter,

Saturn , Uranus, and Neptune. Although these planets are made up of lighter elements, they have a solid core. The atmosphere of all these planets is made up of hydrogen and helium  . In addition to these two elements, the planets Neptune and Uranus.

contain methane.

Explanation:

I mean Saturn would be right for the last one but it was not amongst the options so it would be Uranus

the methane gas [ CH4 ] would be found on Neptune and Uranus.

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.
