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.
Hydrogen bonds i hope that helps
Answer:
Prokaryotes do not have introns, eukaryotes have introns
Explanation:
Prokaryotes do not have introns, eukaryotes do. Introns are regions of DNA that are transcribed but not part of the final protein. They interrupt exons, which are the coding parts of the gene. These are only present in eukaryotes.
Introns need to be removed before the mRNA can be translated into the protein sequence. This occurs by a process called splicing. The splicing machinery binds the junction between introns and exons and excises the intron. The exons are then fused together to create the mRNA.
Other processing steps occur to the eukaryotic pre mRNA to prevent it from being degraded in the cell. This includes adding a cap to the 5' end of the protein, and adding a poly A tail to the 3' end. One these steps are complete, the eukaryotic mRNA is complete.
The prokaryotic mRNA undergoes transcription and translation simultaneously because it doesn't require these processing steps.
The appropriate response is Nitrogenous Base. It is just a nitrogen containing atom that has an indistinguishable concoction properties from a base. They are especially vital since they make up the building pieces of DNA and RNA: adenine, guanine, cytosine, thymine and uracil.
Answer:
If a group made up of 50% boys and 50% girls is asked to read a passage, then the girls will remember more of what they read than the boys because girls have better memories than boys.
Explanation:
A hypothesis is a statement that explains what you think will happen in an experiment and why. It is framed as "if...then...because." The "because" part should be based on research and not personal opinion. A good hypothesis will be more than a single sentence, and will cite research on the subject.
