What is the major difference between bacterial chromosomes and eukaryotic chromosomes?.
Sphinxa [80]

The major difference between bacterial chromosomes and eukaryotic chromosomes is that bacteria have a single circular chromosome whereas eukaryotes have several linear chromosomes.

Eukaryotic chromosomes are present within the nucleus while prokaryotic chromosomes are found in the nucleoid (a region of the cytoplasm). The nucleoid does not have a membrane.

In eukaryotic chromosomes, DNA is wrapped around histone proteins, which is further compacted by supercoiling and folding. However, in prokaryotic chromosomes, DNA is supercoiled and held together by nucleoid-associated proteins.

Prokaryotic chromosome is very simple in comparison to the eukaryotic one. Prokaryotic chromosome lack telomeres and centromeres sequences which is found in the eukaryotic chromosomes.

Which of the following statements is true?
Paraphin [41]

Functionality of Genes and chromosomes is described below.

Explanation:

  • Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.
  • Genes are contained in chromosomes, which are in the cell nucleus.
  • A chromosome contains hundreds to thousands of genes.Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
  • A trait is any gene-determined characteristic and is often determined by more than one gene.Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
  • The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
  • the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
  • The phenotype is the actual structure and function of a person’s body. The phenotype is how the genotype manifests in a person—not all the instructions in the genotype may be carried out (or expressed). Whether and how a gene is expressed is determined not only by the genotype but also by the environment (including illnesses and diet) and other factors, some of which are unknown.
  • A karyotype is a picture of the full set of chromosomes in a person’s cells.

The cells that respond to changes in blood gas concentration and generate the respiratory rhythm are found in several nuclei in
levacccp [35]

The answer is; medulla oblongata and pons.  

In this region of the brain, there are chemoreceptors that can detect changes in the pH of the blood. These are called central chemoreceptor. There are also chemoreceptors in the arteries called peripheral chemoreceptors. When these chemoreceptors detect a drop in the blood PH (due to increased dissolved carbon dioxide in the blood), the depth and rate of breathing is increased in the lungs.

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing what?
Mashutka [201]

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing "an influx of Cl-".

<u>Explanation:</u>

The neurotransmitters which have inhibitory influence on the neuron are termed as "Inhibitory neurotransmitters". The major inhibitory neurotransmitters involve serotonin and gamma-aminobutyric acid (GABA) in the brain and brain stem (spinal cord) respectively.

GABA uptake is temperature and ion-dependent as require both N a^{+} and C l^{-}. Even glycine transporters are also members of the large family of N a^{+} / C l^{-} dependent neurotransmitter transporters. Both of them with the GABA transporters share approximately 50% sequence identity.
