Describe the ways mutations can affect DNA and chromosomes.​
lozanna [386]
Mutations present permanent and heritable changes in the genome. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Deletion presents a loss of nucleotides which changes DNA sequence. When new nucleotides are embedded in the DNA chain, it is known as insertion. Substitution implies the process where new nucleotides are inserted while the ones that were present in that specific spot in a DNA molecule are deleted.
Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations - deletion, duplication, inversion, and translocation. In deletion, a whole or one part of a chromosome is lost. Duplication presents an extra copy of a whole or one part of a chromosome. In an inversion, parts of a chromosome change order, while in translocation a part of one chromosome detaches and then connects to another.

Which two molecules generated by the Krebs cycle pass their high-energy electrons to the electron transport
Sidana [21]

<u>Answer</u>:

The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and  FADH2

<u>Explanation:</u>

The kreb's cycle gives NADH and also the another hydrogen carrier which is termed as FADH2. During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, which has enough potential energy that can convert and produce 3 ATP molecules. Again in the electron transport chain the NADH and the FADH2 undergoes oxidation and releases energy in the form of the ATP. The process of generation of the ATP in the electron transport chain(ETC)  is also referred as the chemiosmotic phosphorolation.
