Approximately what percentage of the human genome is composed of repetitive sequences?

Biology
1 answer:
Arturiano [62]4 years ago
4 0
Approximately 50% of human genome is composed of repetitive sequences. It contains approximately 3 billion of these base pairs that reside with 23 pairs of chromosome within the nucleus or our cells or called nucleotides. Genes in the genomes of invertebrates such as Drosophila is not like the human genes because the human genes contain more and larger introns than the genes in the genomes. The human genes are larger than the genes in the genomes. The genome sequence is ~99.9% similar in individuals of all nationalities. Complete set of deoxyribonucleic acid of a single cell of an organism or sequence for humans (Homo sapiens) is called Genome. It includes both protein-coding deoxyribonucleic acid genes and noncoding deoxyribonucleic acid.

Explanation:

The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:

They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.

In terms of ATP, how much more energy does the aerobic respiration process produce?
andrew-mc [135]

Answer:

Aerobic respiration process produce either 36 ATP or 38 ATP depending on the amount of NADH moles while Anaerobic produces 2 ATP. Aerobic respiration produces 32-34 ATP more

Explanation:

Aerobic respiration has 3 steps which includes; Glycolysis which produces 2ATP; Krebs cycle which produces 2 ATP and Electron Transport Chain which produces 32 - 34 ATP depending on the molecule of NADH introduced into the reaction from the kreb cycle

Gennadij [26K]
<span>1. Protozoa are single celled, eukaryotic organisms that exhibit animal-like behaviour. 2. Viruses consists only of genetic material and a protein coat, and they are known to cause a wide variety of diseases such as AIDS. 3. Fungi have characteristics similar to plants, but they do not have root systems like plants do and they also do not rely on chlorophyll to photosynthesize. 4. Bacteria make up this category. 5. Rickettsiae is a genus of bacteria that are intracellular parasites.</span>

A student analyzed a viral genome and found that the genome had the following nucleotide composition.
lapo4ka [179]

Answer:

Option A) Double-stranded DNA

Explanation:

Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.

Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.

Thus, the structure of the viral genome is Double-stranded DNA.
