Global climate change occurs because increasing concentrations of greenhouse gases in the Earth's atmosphere trap more of the sun's energy, causing the Earth's temperature to rise. The primary greenhouse gases responsible for this effect are carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), etc.
As these gases accumulate in the atmosphere, they absorb and trap more of the sun's energy, causing the earth's temperature to rise. This warming effect leads to a range of climate changes, including rising sea levels, more frequent and intense heatwaves, changes in precipitation patterns, more severe storms, and other weather-related events.

Genes that frequently cross over together are said to be {{c1::linked}}
Genes that frequently cross over together are said to be linked. Linked genes are often found on the same chromosome and tend to be inherited together, resulting in their traits being closely associated.
Genes that frequently cross over together are said to be linked. This means that they are located close to each other on the same chromosome and tend to be inherited together as a unit. Linkage is measured by the frequency of recombination between two genes, which is the process where genetic material is exchanged between homologous chromosomes during meiosis. If two genes are very close together, they are less likely to undergo recombination and will remain linked.
However, if they are far apart, they are more likely to undergo recombination and will segregate independently. Therefore, the degree of linkage between two genes can vary depending on their physical distance from each other on the chromosome.

What type of plasmid must a bacteria contain to undergo conjugation?
Bacteria must possess a type of plasmid called a conjugative plasmid in order to undergo conjugation. The presence of a conjugative plasmid is necessary for bacteria to engage in conjugation, which is an important mechanism of horizontal gene transfer that contributes to bacterial diversity and evolution.
Conjugative plasmids carry genes that encode for the machinery required for conjugation, including a sex pilus or other structure that allows for physical contact between donor and recipient cells. Once the cells are in contact, the plasmid is transferred from the donor cell to the recipient cell through a specialized mechanism that involves the formation of a conjugation bridge or mating bridge. Conjugative plasmids can carry a wide variety of genes, including antibiotic resistance genes, virulence factors, and metabolic pathways. Their ability to transfer these genes horizontally between bacteria makes them an important contributor to the spread of antibiotic resistance and other pathogenic traits.

how can a genetic disorder be dominant even if the deleterious sequence is only inherited from one parent, and there is still another normal allele?
A genetic disorder can be dominant if a single copy of the mutant allele is enough to cause the disease. This can occur if the mutant allele produces a protein that interferes with the normal function of the protein produced by the normal allele.
In the event of a dominant genetic illness, even if the other allele is normal, just one copy of the mutant allele is enough to result in the disease. This is due to the possibility that the mutant protein may impair the normal operation of the protein generated by the normal allele, which would result in illness symptoms. In contrast, for a genetic illness to be recessive, both copies of the gene must be altered. The person is a carrier but does not get sick if only one copy is altered. Gain-of-function mutations, in which the mutant protein acquires a new harmful activity, are the source of certain dominant genetic illnesses, whereas dominant-negative mutations, in which the mutant protein impairs the function of the normal protein, are the cause of others. In either case, the presence of a single copy of the mutant allele is enough to cause the disease.

The reasons why very few differences in DNA sequences between two people alter the amino acid sequences of proteins are mutations do not occur within coding sequences. a very small percentage of the human genome consists of codons within genes, all mutations within codons are repaired by dna repair machinery, many mutations within codons are silent, and natural selection might lead to the disappearance of deleterious mutations.
First, a small percentage of the human genome consists of codons within genes, which means that many mutations may occur in non-coding regions and not affect the amino acid sequences. Second, many mutations within codons are silent, which means they do not change the amino acid that is coded for, due to the redundancy of the genetic code, this phenomenon allows for variations in the DNA sequence without altering the protein's structure or function. Third, the DNA repair machinery is efficient at repairing mutations within codons, ensuring that most errors in DNA replication are fixed before they can cause changes to amino acid sequences.
Lastly, natural selection plays a role in the preservation of functional proteins. Deleterious mutations, which negatively impact the organism's fitness, are likely to be removed from the population over time. This selective pressure helps maintain the integrity of amino acid sequences in proteins and limits the impact of DNA sequence differences between individuals.

sucralose or better known as splenda is the chlorinated form of sucrose, but it is not metabolized through glycolysis like sucrose which can be broken down into glucose and fructose. provide a reasonable explanation for this. hint: look up the structure of sucralose and sucrose and consider how sucrose is metabolized through glycolysis. this may require you to look up material on your own that is not explicitly covered in lecture.
Sucralose, better known as Splenda, is the chlorinated form of sucrose, and it is not metabolized through glycolysis like sucrose, which can be broken down into glucose and fructose. The reason for this lies in the molecular structure of sucralose compared to sucrose.
Sucrose is a disaccharide composed of glucose and fructose units, connected by a glycosidic bond. During metabolism, the bond is cleaved by the enzyme sucrase, releasing glucose and fructose. These monosaccharides then enter glycolysis, a series of enzymatic reactions that generate energy in the form of ATP.
Sucralose, on the other hand, is synthesized by replacing three hydroxyl groups in sucrose with chlorine atoms. This modification significantly changes its structure, making it resistant to the action of sucrase. As a result, sucralose remains intact and is not broken down into glucose and fructose. Consequently, it does not enter glycolysis, and the body does not metabolize it for energy.
In summary, the structural differences between sucralose and sucrose prevent sucralose from being metabolized through glycolysis. Sucralose's chlorinated structure makes it resistant to enzymatic breakdown, allowing it to pass through the digestive system without being utilized for energy.
