Choose the best answer. Processing of rRNA Answer 1 Used in degrading mRNA Answer 2 Contains codons Answer 3 Component of ribosomes Answer 4 Brings amino acid to ribosome Answer 5 Processing of mRNA Answer 6

Component of ribosomes: Ribosomes are organelles involved in the protein synthesis they made up of r-RNA and proteins.They play a role in the alignment of amino acids during protein synthesis.

Used in degrading mRNA: SiRNA is small synthetic RNA molecule used for gene silencing experimentsIt is the 18-25bp length and it binds to its complementary m-RNA and degrades it.

Brings amino acid to ribosome:t-RNA is called transfer RNA because it transfers amino acids during protein synthesis. Each amino acid is carried by its particular t-RNA molecule.

Processing of mRNA & Processing of rRNA: Sn RNA is small RNA molecules involved in the splicing and processing of RNA molecules they are located in the nucleus.

Contains codons:m-RNA are intermediate molecules of DNA and protein synthesis and they carry a message regarding the sequence of amino acids. The message carries in the form of codons.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
