What are the chromosomes called when they look like Xs​

Biology
1 answer:
Marina86 [1]3 years ago
6 0

Answer:

I think you're referring to the Metaphase...

Explanation:

During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".

These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.

This "Zipping Up" makes the chromosomes more visible.

As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....

Why do sugar nucleotides, such as udp-glucose, play a role in glycogen synthesis, rather than sugar phosphates, such as glucose-
HACTEHA [7]

Glucose binds to the glycogenin protein to form the glycogen polymer. Glycogen synthase uses UDP glucose as the substrate for polymerization via (1-4) bonds. The branching enzyme has two distinct functions: it breaks the linear chain and forms a branch using a (1-6) linkage.

<h3>What are nucleotides?</h3>

A nucleotide is the primary component of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA), a phosphate group, and a nitrogen-containing base. DNA nucleotides include adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the nucleotide uracil (U) replaces thymine. Polymeric DNA and RNA molecules are composed of long strands of nucleotides.

Water-storing plants and deeply rooted shrubs are plants that characterize?
Nady [450]

Desert vegetation or xerophytes includes bushes with deep roots and plants that store water.

Another name for desert plant:

A plant species known as a xerophyte has evolved to live in environments with little fluid water, like a desert or an area surrounded by ice or frost in the Mountains or the Polar regions. Cacti, pineapples, and various Gymnosperm species are a few well-known instances of xerophytes.

  • Xerophytes have different adaptations to their morphological characters (morphology) and basic physiological functions (physiology) that allow them to store significant amounts of water and save it during dry seasons. During prolonged periods of severe dehydration or evaporation of their organs, some creatures can live, and at those times, their biochemical function may cease. Xeromorphic flora has such biological and morphological modifications.
