Nuclear envelope: how does the nuclear envelope protect the nucleus? What is the function of the nucleus? Describe the structure of the nuclear envelope and explain how it supports the roles of the nucleus, nuc
DNA is our genetic code, whereas RNA has multiple functions, including being a messenger of the genetic code, a site of protein synthesis, and a transporter of amino acids.Answer and Explanation: The nucleic acids DNA and RNA are polymers composed of many individual nucleotides. Each nucleotide ...
Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one...
During the cell cycle, replication and mitosis are the stages at which epigenetic memory is most likely to be erased. Each stage presents a different molecular challenge to memory. During replication, newly assembled chromatin is acetylated and may favour an active PRE but challenge a silent one....
What is a nucleus for? The nucleuscontrols and regulates the activities of the cell (e.g., growth and metabolism)and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. ...
Many of the hrp–hrc genes encode structural components of theT3SS. Exopolysaccharide (EPS). High-molecular-mass polymers that are composed of sugar residues and are secreted by a microorganism into the surrounding environment. T3SS effector (T3E). Virulence proteins that are produced in many Gram...
In this process, genetic traits are passed on from parents to child. You might inherit your father’s nose, or your mother’s curly hair. But this doesn’t mean we are exact clones of our parents.Gametes(the chromosome-containing cells we get from our mom, an egg/ovum and dad, a spe...
internal structures and external appendages. Unlike mammals and other eukaryotes, bacteria do not possess a nucleus; instead, the chromosomal DNA is found in a dense region of cytoplasm known as the nucleoid. Extra ring-shaped DNA is also found in some bacteria and these are known as plasmids ...
The controlled degradation of cellular components that occurs during apoptosis is regulated by caspases, which are a family of proteases activated during apoptosis (more details here: Caspase family). In healthy cells, caspases exist as proenzymes in their inactive forms. Apoptotic signaling activates ...
