Answer:
True
Explanation:
DNA packaging in chromatin and the modifications are fundamental to the genetic expression.
Structure and modifications of chromatin regulate DNA metabolic processes, including transcription, recombination, reparation, etc.
Modifications that affect the way in which the DNI is packaged and used, but do not affect DNI sequences, are known as epigenetic modifications, and different enzymes are in charge of them.
Modifications might function by interfering between nucleosomes contact, or interacting with effector, or translating proteins.
Effector proteins initiate biological responses such as the activation or repression of transcription.
Packaging in chromatin has a big influence on genetic transcription. Genetic expression requires transcription factors that, once joined to genes regulatory sequences, initiate modification cascades that result in a gene expression or silence. Some of the chromatin modifications have been associated with genic activation or repression.
Answer: Enzymes are made out of amino acids, and they are proteins.
Explanation: When an enzyme is formed, it is made by stringing together between 100 and 1,000 amino acids in a very specific and unique order. The chain of amino acids then folds into a unique shape.
Answer:
See explanation
Explanation:
In a situation whereby a plant is in an environment where light is not totally absent, the plant continues to photosynthesize at a slower rate.
Recall that photosynthesis is the process by which green plants make their own food in the presence of sunlight, chlorophyll, carbon dioxide and water.
In a low light, plants are forced to stretch towards the low light source. This is known as etiolation of plants.
Bacteria is the correct answer
Must contain producers, consumers, decomposers and dead inorganic matter
