What Can RNA be compared to?
The chemical structure of RNA is very similar to that of DNA: each nucleotide consists of a nucleobase a ribose sugar, and a phosphate group.
What is an analogy for RNA polymerase?
In our analogy, RNA polymerase is like a scribe who must find instructions inside the DNA file cabinet at the nucleus headquarters. He doesn’t want to photocopy everything in the DNA, like DNA replication.
What is a good analogy for DNA?
Conclude that the thread of cotton is wound around the spool made of wood. Equate the substance DNA (one molecule per one spool) to thread and the substance wood to the protein (histone) it’s wound around (even though DNA is not actually wound around the histone in this manner.)
What would RNA be in a factory?
A workhorse in the factory Among RNA’s most important roles is the transcription and delivery of genetic instructions from the nucleus to the cytoplasm where proteins are made. RNA also has catalytic, structural and regulatory roles.
What is RNA in simple terms?
RNA stands for ribonucleic acid, which is a long, single-stranded chain of cells that processes protein. An example of RNA is a chain of cells that carries genetic information of many viruses from the cell to the cytoplasm.
What is RNA function?
Function. The primary function of RNA is to create proteins via translation. RNA carries genetic information that is translated by ribosomes into various proteins necessary for cellular processes. mRNA, rRNA, and tRNA are the three main types of RNA involved in protein synthesis.
What is an analogy for RNA and DNA?
A copy must be made. These copies are analogous to messenger RNA (mRNA). The library is analogous to the nucleus of the cell. Within the nucleus is the DNA.
What is an analogy for ribosomes?
Ribosome- The site where amino acids are hooked together to make proteins. Ribosome are like a factory, because ribosomes make proteins like factories make different products.
What is the role of tRNA in a factory?
The purpose of transfer RNA, or tRNA, is to bring amino acids to the ribosome for protein production. To make sure that the amino acids are added to the protein in a specific order, the tRNA reads the codons from the messenger RNA or mRNA.
Which RNA copies the DNA code?
messenger RNA (mRNA) molecules
The majority of genes carried in a cell’s DNA specify the amino acid sequence of proteins; the RNA molecules that are copied from these genes (which ultimately direct the synthesis of proteins) are called messenger RNA (mRNA) molecules.
How do you explain RNA to a child?
RNA is a copy, or a transcription, of DNA. See, the DNA is very important, since it holds the information needed for making new cells and maintaining life, so it never leaves the nucleus. The RNA is the one that goes out to do work throughout the cell.
What is RNA example?
Examples of small RNAs are transfer RNA (tRNA), 5S ribosomal RNA (rRNA), microRNA (miRNA), small interfering RNA (siRNA), small nucleolar RNA (snoRNA), Piwi-interacting RNA (piRNA), tRNA-derived small RNA (tsRNA), and small rDNA-derived RNA (srRNA).
