Fundamenta la idea, existe vida EXTRATERRESTRE?

si

Explanation: sí, la vida extraterrestre tiene que existir en algún lugar dentro del universo, en un planeta tiene que haber vida incluso tan pequeña como una bacteria, pero si estamos hablando de vida eucariota, como animales, insectos y plantas, tiene que haberla porque hay millones. de planetas dentro de esta galaxia solamente y hay miles y millones de galaxias que existen; por lo tanto, la vida extraterrestre tiene que existir.

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.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
