Once the DNA’s nucleotides have been copied, the mRNA can leave the nucleus of the cell and makes its way to the cytoplasm, where protein synthesis takes place. Here, complicated molecules called ribosomes ‘read’ the sequence of bases on the mRNA molecule. Individual amino acids, which co...
The nucleus is an organelle that contains the genetic information for that organism. In an animal cell, the nucleus is located inthe central region of the cell. In a plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the center of the cell....
the cell makes a copy of the gene, using not DNA but ribonucleic acid, orRNA. RNA shares a similar structure to DNA, except it contains only one strand, rather than two — so it looks like just one half of a ladder. In addition, while RNA has three of the four nitrogen bases in ...
to form structures calledchromosomes. Each chromosome contains a single DNA molecule, wrapped tightly around spool-like proteins called histones, which provide chromosomes their structure. Humans have 23 pairs of chromosomes, which are found inside each cell's nucleus, the control center of the cell...
told, you’ve nearly 20,000 genes, your genes are small parts of a long molecule, called DNA, or deoxyribonucleic acid. If you lined up all of the DNA containing all of your genes, it would measure six feet long, but it’s coiled, so tightly that it fits in just one cell nucleus...
What is the non-living part of a plant cell? What is the smallest part of a cell? What are cuboidal cells? What does a nucleus do in a plant cell? What are mesodermal cells? What is another name for a prokaryotic cell? What must a cell do first to divide successfully?
About three quarters of the sun is hydrogen, which is constantly fusing together and creating helium by a process called nuclear fusion. Helium makes up almost the entire remaining quarter. ... Instead, the sun is composed of layers made up almost entirelyof hydrogen and helium. ...
The CN cycle begins with the nucleus of a carbon-12 atom using it as a catalyst — an element that speeds up a reaction but is unchanged at the end of it — for fusion. Carbon-12 through proton capture goes through various stages until a helium atom is emitted and carbo...
a将除属性核以外的属性顺序加入属性核中,每次加入属性重要度为最大值的属性。 Will join in the attribute nucleus besides the attribute nucleus attribute order, each time will join the attribute importance for the maximum value attribute.[translate] ...
