Nucleolus- the nucleolus synthesizes ribosomal RNA (rRNA). Afterwards, these are put together with the proteins produced in the cytoplasm to create ribosomal units. 3. Nuclear Envelope-
1. How does DNA encode information? DNA is a double-stranded helix composed of a phosphate backbone and deoxyribose, and encodes information by the sequence of its nucleotide bases, which are composed of adenine, thiamine, guanine and cytosine. DNA undergoes transcription, which produces single-stranded mRNA, which uses uracil in place of thiamine. Next step is translation, in which the RNA becomes a protein, which then can act as structural units or enzymes.
1a. Review: Describe three main differences between RNA and DNA. The three main differences between RNA and DNA are as follows: RNA has the sugar ribose instead of deoxyribose, which DNA has, RNA is single-stranded while DNA is double-stranded, and RNA uses uracil instead of thymine. 1b.
Wachtershauser says that amino acids could have been created deep in the earth’s crust and these amino acids were brought up with other hydrothermal material into colder waters. Experimental research shows that minerals inside hydrothermal vents have the same properties to enzymes and are able to create simple organic molecules such as methanol and formic acid out of dissolved carbon dioxide in the water. A man by the name of Joan Oro found that the nucleotide base adenine can be made from hydrogen cyanide and ammonia in a water solution. His experiment created a lot of adenine, the molecules of which were formed by 5 molecules of hydrogen cyanide. Experiments done later showed that the other RNA and DNA nucleobases can be created with simulated prebiotic chemistry with a reduced
The two chains are form a double helix structure, with the pattern of each chain complementary to the other, with Adenine hydrogen bonding to Thymine, and Guanine hydrogen bonding to Cytosine. The DNA along with specific proteins are further organised into Chromosomes, individual continuous pieces of DNA. b.)
The monomers of lipids are fatty acids and glycerol. When lipids bond with phosphorous, it creates a phospholipid, which is what is used to create your cell membranes. Nucleic acid is very important because it determines who you are. If there weren’t nucleic acids, we wouldn’t be able to have children because there would be no way to determine their genetics. Nucleic acids are also very good to eat because they contain phosphorous and nitrogen, which are also in other macromolecules.

Deoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell.
The first step, transcription, happens in the nucleus, which holds our DNA. A membrane called the nuclear envelope surrounds the nucleus, and its job is to create a room within the cell to both protect the genetic information and to house all the molecules that are involved in processing and protecting that info. This membrane is actually a set of two lipid bilayers, so there are four sheets of lipids separating the inside of the nucleus from the cytoplasm. The space between the two bilayers is known as the perinuclear space.
DNA is made up of nucleotides, and the nucleotides contain a phosphate group, a 5-carbon sugar, and a nitrogenous base. There are four bases for DNA. They are Adenine (A), Cytosine (C), Guanine (G), and Thymine (T). The sequence of these bases determines DNA’s genetic code. According to Genetic Alliance, epigenome is a series of chemical tags that lie on top of your genes, and tell your body which genes to read and how often to read them.
The 1st lane found in the left most side is the protein ladder, which has known molecular weight and functions as the ‘ruler’ for the molecular weight of the unknowns. The 2nd band represents the microsome, followed by the crude then another microsome. The 5th band is the nuclei and the 6th and 7th bands are the replicates of the soluble and the nuclei
It is an exciting era for the Scientific Community. The human nuclear genome contains 3, 200, 000, 000 nucleotide base pairs, the basic molecules of DNA (deoxyribonucleic acid), the very idea that
The sequence of the bases provides the information, so the DNA is like the hard
The newly made mRNA strand travels out of the nucleus to a ribosome where the directions can be made into a protein. A ribosome is composed of one large and one small subunit that assemble around the mRNA. The mRNA now passes through the ribosome. Now, amino acid building blocks are carried into the ribosome attached to specific transfer RNA (tRNA) molecules. The small subunit of the ribosome arranges the mRNA so that it can be read it segments of 3 nucleotides.
The DNA gathered by the group bore positive results only on Test for Deoxyribose; compared to the standard solution, which bore positive results on all chemical tests, namely, Test for Deoxyribose, Test for Phosphate, Test for Purines, and test for Pyrimidines.
