Answer:

Chromatin helps regulate DNA replication.

Explanation:

Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).

Yuliya22 [10]

Answer:

B) a signal-recognition particle that brings ribosomes to a receptor protein in the ER membrane.

Explanation:

Each synthesized protein has to be targeted to the specific location and transported to that location. There are two possible ways for that transport: post-translational transport or co-translational transport.

• Co-translational transport occurs during the process of translation, and proteins transported this way are proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome), plasma membrane proteins or proteins for the exterior of the cell. They have an amino sequence called a signal peptide which sends them to ER first.

• Proteins that do not have a signal peptide stay in the cytosol so, their transport is after the translation (post-translational).

lorasvet [3.4K]

A hormone released in the small intestine that stimulates the pancreas to release digestive enzymes and the gallbladder to release bile is known as Cholecystokinin.

Hormones play a huge position for your normal functioning. They manage heart rate, sleep cycles, sexual feature, and replica. Your metabolism, urge for food, growth and development, temper, strain, and body temperatures are all suffering from hormones.

Cholecystokinin is secreted by using cells of the upper small gut. Its secretion is stimulated by using the advent of hydrochloric acid, amino acids, or fatty acids into the belly or duodenum. Cholecystokinin stimulates the gallbladder to settlement and launch stored bile into the gut. Cholecystokinin (CCK) is produced more often than not inside the duodenum and the jejunum. The physiological roles of CCK are the stimulation of pancreatic secretion and the contraction of the gall-bladder. Secretin and CCK are peptide hormones secreted via the endocrine cells inside the gastrointestinal tract. Secretin stimulates the secretion of water and bicarbonate ions from the pancreas, while CCK stimulates the synthesis and secretion of bile juice and pancreatic enzymes.
