1. true of false: rrna refers to regular rna. 2. describe transcription and its role in the central dogma of molecular biology. answer the question using complete sentences.

1. Answer;

The statement is False

Explanation;rRNA refers to ribosomal RNA. rRNA is a type of RNA (ribonucleic acid). Ribosomal RNA, together with ribosomal proteins makes up the ribosomes, the organelles that are responsible for the process of translation.Ribosomes, carries out the process of translation, which transfers the information contained in the messenger RNA to make proteins, with the help of transfer RNA, tRNA.2. Answer and explanation;Central Dogma is the theory that describes protein building in the order; DNA to RNA to protein. DNA is transcribed to RNA which is translated to protein. Protein is never back-translated to RNA or DNA; DNA is never directly translated to protein.Transcription is the process by which a DNA sequence of a gene is transcribed or copied to make an RNA molecule. The reaction is catalyzed by RNA polymerase.The process occurs in the nucleus of organisms in eukaryotes and in the cytoplasm for prokaryotes. It makes an mRNA copy of DNA instructions to allow the instructions to leave the nucleus.

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.

I’m not exactly sure what your trying to ask, but if it’s how an organelle is similar to a body system or a part a nucleus is like a in function. but i don’t fully understand what you’re trying to ask
