The following table shows some characteristics of an eclipse which was observed from a certain location on Earth.
Aloiza [94]
Part 1: The eclipse observed was a lunar eclipse. The sun is usually not visible during these eclipses. The moon is new during a solar, but full during a lunar. It is red during a lunar eclipse due to a reflection of the Suns light behind earth. It happens more often because Earths shadow is larger than the moons. The umbra is larger as well, so it lasts longer than a solar eclipse.

Part 2: The moon is in the full moon phase. The Earth is in between the Moon and the Sun. The umbra of Earths shadow is cast directly on the moon, casting out the suns light. A tint of the reddish color shines around earth from the Sun making the dark moon appear red. The moons axis is slightly tilted , so the umbra does not hit the moon every month. But when it does? It creates a lunar eclipse.

How could an error during transcription affect the protein that is produced?
Ahat [919]

Answer: An error during transcription could produce a shorter protein or induce changes in the protein's sequence.

Explanation: Transcription is the process of single-stranded RNA synthesis from a DNA template (gene). During this process, RNA polymerase reads the DNA template and synthetize RNA, keeping the sequence. The RNA sequence will be reading later by ribosomes and protein will be produced. An error in transcription could produce changes in codons that are sequences of 3 nucleotides that determine  aminoacids of the protein, and that would change protein folding and inactive it. Another possible result would be that  error in transcription produce a premature stop codon that cause a shorter inactive protein.
