DNA is bound together by covalent bonds between different molecules. It also contains proteins, which again are held together in their specific structures by covalent bonds.
Covalent bonds may be broken when high temperatures are applied. The temperatures that a food encounters during the cooking cause the DNA to be denatured, meaning it cannot be extracted. The same occurs with other proteins such as enzymes and antibodies.
Answer: false
Explanation:
we can say that the genetic map has 2 options
A …12 mu …X35 …12 mu … p2
with the fact of knowing the location of a single gene we can define the distances that the genes have, as in the previous graph, however when the "A" gene is located in the middle of the map the distance of the X35 gene will no longer be 12 mu with respect to the locus p2 gene and the X35 gene will have 36mu with the locus p2 gene
X35 … 12 mu … A …24 mu …p2
When finding the gene "A" is in one of the genetic maps, we can affirm that the answer is correct
A …12 mu … X35 …12 mu …p2
Answer:
Uracil goes with Adenine, Guanine goes with Cytosine. Ie. A with U, G with C. Generally, Adenine goes with Thymine, but RNA uses uracil instead of thymine. Just make 9 of those.
Explanation:
Answer:
The statement true of all proteins, carbohydrates and fats is that human body is able to synthesize them all.
The statement unique to proteins is that proteins are made up of instructions according to DNA.
Explanation:
Carbohydrates, Proteins and fats are macronutrients and required by body in larger amounts. All these macromolecules are made up of building blocks like proteins are from amino acids, carbohydrates from monosaccharides and fats from triglycerides. Human body can also synthesize these macronutrients. Like proteins can be synthesized by central dogma. Glucose can be synthesized by gluconeogenesis from glycogen and fats can be synthesized from acetyl-CoA and NADPH.
The proteins are made up by a process known as central dogma. The first step of central dogma is replication in which a replicated copy of DNA is produced in a cell. The second step is transcription for the production of messenger RNA from DNA. At last mRNA is used for the production of proteins on ribosomes.
The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.
