Answer:
During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.
I hope it's helpful!
Answer:
multidimensional
Explanation:
Development is multidimensional
By multidimensionality, we mean a complex and dynamic interaction of factors that control development all through the lifespan, it as to do it biological, cognitive, and socioemotional changes.
Let's take for instance, in adolescence, puberty comprises of physiological and physical variations with variations in hormone levels, the formation of primary and secondary sex characteristics, changes in height and weight, and varying other bodily alterations. The cognitive changes (increment in thinking- abstractly), emotional and social changes (controlling emotions and relationships with equals, falling in love).
Puberty deals with a wide range of domains that exemplifies the multidimensionality component of development.
During the process of shedding their exoskeleton, called molting, insects can become very vulnerable because they lack a protective layer on their bodies.
Recent studies have also shown that the molting in aquatic insects can remove a layer of tracheids, the structures that these insects use to breathe.
They all are unicellular ;)
Answer :Enhanceosome<span>
Protein complex that binds enhancer elements and directs DNA bending into loops that bring the protein complex into contact with RNA polymerase and transcription factors bound at the core promoter or with protein complexes bound to proximal promoter elements.
</span>Answer: enhanceosome
<span>
a large protein complex formed by the aggregation of multiple proteins, a few binding enhancer sequences and others binding other proteins.
They direct DNA bending into loops that bring the enhanceosome into contact with RNA polymerase and transcription factors bound at the core promoter or with protein complexes bound to proximal promoter elements.
The DNA loops can be small or large, in keeping with the observation that enhancers many be close to or quite distant from the genes they regulate.
