DNA and RNA are made up of monomers called nucleotides. - DNA and RNA both have 3 nitrogenous bases: Adenine, Cytosine and Guanine. - DNA and RNA both have a phosphate groups in their nucleotides. Sometimes called phosphoric acid
<span>Structurally, DNA and RNA are nearly identical. However, there are fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine. DNA is usually double-stranded (double helix) and most cellular RNA is single-stranded (single helix). In DNA, the common organic bases are adenine, guanine, cytosine, and thymine. In RNA on the other hand, the common organic bases are adenine, guanine, cytosine, and uracil. Transcription is the process of converting DNA into a correlative RNA code, or in other words, making an RNA copy of a gene sequence. This copy is called a messenger RNA molecule, or mRNA. It is basically a large group of RNA molecules that transport genetic information from the DNA to the ribosomes. The mRNA does this by leaving the cell nucleus and entering the body of the cell, which is the cytoplasm. During translation, protein is assembled when the ribosomes translate the sequence in the arriving mRNA. They then bring in the appropriate amino acids needed to complete the protein synthesis. Together, transcription and translation are referred to as gene expression. RNA consists of three major types: mRNA (messenger), tRNA (transfer), and rRNA (ribosomal). As said before, mRNA serves as temporary copies of DNA information. tRNA on the other hand, are the ones that transfer the amino acids to ribosomes in order that they can be assembled into protein. Finally, there is rRNA, which has an entirely different function altogether, as a molecular component of the ribosome. In short, rRNA is essentially the cell’s main protein factory. While it does not make proteins directly, it does produce and link together assemblies of amino acids (polypeptides) that have the job of making them. * Sorry I just had a paper on this and feel like spouting a whole bunch of info</span>
a. New Orleans, because pressure increases as you get deeper in the atmosphere and closer to the center of Earth
Explanation:
Low altitudes: There is more atmospheric pressure in comparison with higher altitudes. When closer to the Earth core, the more pressure and temperature there is.
High Altitudes: As high increases, atmospheric pressure, and temperature, decreases, leading to a lower oxygen partial pressure in the environment.
At sea level, the atmosphere pressures the earth's surface with approximately 1-kilogram per square centimeter strength. This means that at sea level, there is one ton of air making pressure over us. But this air pressure decreases with altitude.
At high level there is less air making pressure from above, and there is less gravity acting. Molecules are more separate from each other, and the density decreases.
Incomplete dominance will produce the most pink flowered plants.
<u>Explanation:</u>
Incomplete dominance means when an allele from two homozygous parents combine in the offspring. This offspring contains one allele from one parent and another allele from another parent.
Incomplete dominance doesn’t allow just one allele or trait to dominate rather produces a combination of both
. The Red flower has RR allele and the white flower has WW allele.
When two flowers are crossed there is probability of RR, WW or RW allele to be formed. The RW heterozygous allele forms the pink flower. The two alleles are expressed as Red and White.
Continental collision is a phenomenon of the plate tectonics of Earth that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountainsproduced, and two continents sutured together. Continental collision is known only to occur on Earth.
Continental collision is not an instantaneous event, but may take several tens of millions of years before the faulting and foldingcaused by collisions stops. The collision between India and Asia has been going on for about 50 million years already and shows no signs of abating. Collision between East and West Gondwana to form the East African Orogen took about 100 million years from beginning (610 Ma) to end (510 Ma). Collision between Gondwana and Laurasia to form Pangea occurred in a relatively brief interval, about 50 million years long.
