The salt/detergent was prepared by mixing 1L of distilled water, 50ml of detergent and 7.5 grams of salt. The solution was headed to 60° Celsius and maintained through the lab. The nuclear membrane is made up of phospholipid bilayer, a thin membrane made up of two-lipid bilayer. The soap detergent dissolves the lipid bilayer on the nucleus and cell membrane releasing DNA. NaCl is used to separate proteins from the DNA.…
Oh! That’s like the nuclear membrane in the cell. The nuclear membrane controls what comes in and out of the nucleus.” Phineas says as he knows everything under the sun. 11.…
b-The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes. The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle.…
Its size is 0.025 µm in diameter. 5) Nucleus: - Contains the cell’s genetic material (DNA) and controls all the cell’s processes. - Its size is 5-10 µm in…
There are many organelles in the animal cell. There is the nucleus, endoplasmic reticulum, cell membrane, vacuoles, lysosomes, mitochondria, cytoplasm, ribosomes, & golgi apparatus. The nucleus directs all the cells activities,including reproduction. Endoplasmic Reticulum is a network of membranous tubules within the cytoplasm continuous with the nuclear membrane;It usually has ribosomes attached The cell membrane protects the cell and regulates what substances can enter and leave. Some animal cells have vacuoles that store food, water, & waste.…

Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons to become stable 3. Nucleic acids are organic molecule composed of nucleotides.…
It is composed of nucleic acid and special proteins. Ribosomes are found floating freely in the cytoplasm and some bound to the endoplasmic reticulum (ER).The central function of ribosomes is that they arrange twenty amino acids into particular strands. These strands are turned into a protein molecule. Ribosomes act as building blocks of protein which are essential for human body growth. Ribosome arranges and prepare amino acids so that the rest of the body can use it to grow and function.…
DNA makes proteins. DNA is stored in the nucleus and contains phosphates (a phosphate includes nitrogen bases). DNA is made up of these phosphates, but, in making polypeptides, or a protein, the nitrogen bases are the most important in his process. To make a polypeptide, the helicase unzips the double helix figure, making two rows, or strands, which are one side of all of the nitrogen bases. Floating nitrogen bases string the opposite of these sides, to make an original copy, but leave, ending in one strand of the opposite, original DNA strand.…
The RNA moves in and out of the nucleus through the pores of the nucleus membrane. The Nucleus is also in charge of protein synthesis which also enters through the nuclear…
Each organelle is significant to its cell, which are the building blocks of life. At the center of almost every cell is a dense organelle called the Nucleus. It contains the cell's genetic material and usually has a double membrane. The double membrane that protects the nucleus is similar to the thin single membrane made up of proteins and lipids.…
Transport of proteins into the nucleus occurs via a channel called nuclear pore complex (NPC), which penetrates and spans the nuclear envelope, a double membrane that separates the nucleus from the cytoplasm. The outer nuclear membrane is continuous with the endoplasmic reticulum, hence giving a shorter pathway for proteins to enter the nucleus; inner nuclear membrane contains proteins acting as binding site for nuclear lamina, indirectly providing support for the NPC as the primary function of nuclear lamina is to structurally support the nuclear envelope. NPC is made up of approximately 30 different proteins known as nucleoporins. There are three types of nucleoporins: 1. Transmembrane ring proteins, which anchor NPC onto nuclear envelope; 2.…
Eukaryotes have much larger genomes than prokaryotes, and therefore, must condense their DNA into chromatin. Chromatin is composed of histone proteins that help to condense and organize the DNA forming chromosomes. The basic unit of this chromatin is a nucleosome, which contains about 150 base pairs of DNA that are wrapped 1.7 times around the core histone proteins.…
They both have similar masses. Surrounding the nucleus are electrons. These are arranged in shells, or…
