What has a whiplike tail and a head that is almost all nucleus?
A sperm cell
What is the function of the cap and tail on eukaryotic mRNA?
They are involved in transporting the mRNA outside of the nucleus.
What is the holder and protector of the DNA?
The nucleus, but telomeres protect DNA by adding junk DNA to the ends that way the exons do not get messed with. The 5' Cap and the Poly-A Tail are the two ends of the DNA with junk DNA, or introns.
How is mRNA stabilized before leaving the nucleus for translation?
Before leaving the nucleus, the mRNA is modified (post-transcriptional modification). It is protected from ribonucleases by adding a 5' cap and a (3') poly A tail. These modifications help to stabilise the mRNA by preventing degradation by nucleases.
What is RNA processing?
1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added. 1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added.
Where do the 3 main parts of a comet go?
The three main parts of a comet are the Nucleus, the Coma, and the Tail. The nucleus is the comet itself. In deep space, the comet is frozen solid and almost invisible. As the comet approaches the sun, the Sun's light heats the nucleus of the comet and causes frozen gasses to melt or sublimate, forming a sort of atmosphere around the comet. This is the "Coma" of the comet. The sunlight causes the gasses around the comet to glow. But the gravity of the comet's nucleus isn't strong enough to hold on to an atmosphere, and the Sun's rays push the glowing gasses away from the nucleus, directly away from the Sun. This stream of glowing gas is the "tail" of the comet. It's important to note that the tail of a comet doesn't drag behind the nucleus; the "tail" goes straight from the nucleus away from the Sun, so the "tail" sometimes extends AHEAD of the comet. Because the material of the comet nucleus gets melted and loses mass every pass by the Sun, comets have a limited lifespan. At some point, each comet will break apart into pieces and disappear, leaving only a meteor shower in its wake.
What is long and glowing behind a comet?
It is a tail
What are the parts of a comet?
The coma, nucleus, and the tail
This large body of frozen ice and rock sometimes forms what appears to be a bright glowing tail when it gets near the Sun?
The Sun is pretty hot, so all the ice quickly melt, and you can see a tail! It actually also happens sometimes on the Earth.
Is the glowing tail of a firefly a structural behavioral or physical adaptation?
The glowing abdomen of a firefly is a physiological adaptation also known as bioluminescence.
What state of matter is comets?
The nucleus of a comet is mostly solid, while the coma and tail of the comet is composed of gasses and (we believe) a lot of dust. As the comet approaches the Sun, sunlight heats the nucleus of the comet and melts some of the frozen gasses, which sublimate into space carrying dust into space, forming the coma and the tail of the comet.
What are the parts of a comet after it forms a tail?
The coma, the nucleus, and the tail are the parts of a comet after the tail has formed.
What are celestial comets?
Celestial comets is a more formal name for comets. Comets are objects in space orbiting the Sun with long orbits. They are thought to be made of frozen water. As they near the Sun they produce a long glowing tail trailing behind.
Does a dolphin develop its tail after it's born?
No it does not, it is born with a tail
What are the nucleus coma and tail parts of?
A comet
How is a tail made on a comet?
Comets commonly develop two tails, a vapor trail, which we can see, and a gas/dust trail, which we may or may not be able to see. The tail develops when the heat of the sun causes the ices in the cometary nucleus to vaporize off. The tail always points directly away from the sun.
What is the purpose of a lightning bug?
The female lightning bug uses her glowing tail to attract a mate.
