(vacuole)
vacuola
a cell organelle in plants, fungi, and some protists that stores nutrients, manages waste, and helps maintain cell pressure
(centrioli)
centriolo
a pair of small cylinders near the nucleus in animal cells, organizing cell division by forming the mitotic spindle
(proteina istonica)
istone
a type of protein that plays a structural role in the packaging of DNA into nucleosomes, fundamental units of chromatin
(telomeri)
telomero
a repetitive DNA sequence at the end of a linear chromosome, protecting it from deterioration during replication, and playing a role in cellular aging and cancer development
(fenotipia)
fenotipo
the observable physical and behavioral characteristics of an organism, resulting from the interaction of its genotype (genetic makeup) with the environment
(equilibrio interno)
omeostasi
the tendency of an organism or cell to regulate its internal environment and maintain a stable, balanced condition, despite external changes
(traslazione)
traduzione
the process by which the information encoded in the sequence of nucleotides in DNA is converted into a functional product, typically a protein
(trascrizione genetica)
trascrizione
the process by which a segment of DNA is used as a template to synthesize a complementary RNA molecule
(duplicazione)
replicazione
the process by which an organism duplicates its genetic material, particularly the copying of DNA in cell division
(codone di mRNA)
codone
a sequence of three adjacent nucleotides in mRNA that codes for a specific amino acid during protein synthesis or serves as a start or stop signal in the translation process
(simbiosi mutualistica)
simbiosi
a close and often long-term interaction between two different species living in close physical association, typically to the advantage of both
(amebe)
ameba
a single-celled, microscopic organism belonging to the group of protozoa, characterized by a flexible cell membrane and the absence of a fixed body shape
Informazioni Grammaticali:
(procarionte)
procariote
a simple, single-celled organism that lacks a true nucleus and membrane-bound organelles, such as bacteria and archaea
clorofilla
a green pigment found in all green plants and cyanobacteria that is responsible for the absorption of the sunlight needed for the photosynthesis process
(involucro virale)
capside
the protein coat of a virus that encases its genetic material and helps it attach to and enter host cells during infection
(eucarioti)
eucariote
a type of living thing with cells that have a nucleus and other structures enclosed in membranes, like plants, animals, fungi, and some microorganisms
(uovo)
ovocita
a mature, female reproductive cell or egg, typically larger than a sperm cell, capable of fusing with a sperm cell during fertilization to form a zygote
(enzima digestivo)
pepsina
an enzyme produced in the stomach that helps in the digestion of proteins by breaking them down into smaller peptides
Pepsin is a digestive enzyme that plays a crucial role in the human body's digestion of proteins. It is produced in the stomach and acts to break down large protein molecules into smaller peptides. Pepsin works optimally in the acidic environment of the stomach, where it helps initiate the process of protein digestion, enabling the body to absorb essential amino acids for various biological functions.
(ATP)
adenosina trifosfato
a molecule that carries energy within cells, composed of adenine, a ribose sugar, and three phosphate groups
Informazioni Grammaticali:
(sistema di filamenti proteici)
citioscheletro
a network of protein fibers in a cell that gives it shape, supports its structure, and aids in movement
