aksik [14]

Answer:

Insertion

Explanation:

Mutation is a phenomenon in which the nucleotide sequence of a gene in DNA is changed into a new sequence due to insertion, deletion or  exchange of a gene segment.

Insertion is a type of  mutation in which one or more than pne base sequence in added into the DNA of an organism. This insertion may or may not be dangerous depending on the place of insertion and how it is causing adverse effects on the protein product of the gene.

Here is an example of insertion mutation:

Base sequence: AUG GCC TGC

Product:           met     ala      gln

Insertion:

Base sequence: AUG GCC   C TG     C

Product:              met     ala      Leu

So we can see that the product protein is changed because of insertion.

Hope it helps!

Which of the following situations or phrases most accurately describes the citric acid cycle?
Bond [772]

The correct answer is: B) "All roads lead to Rome"

Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.

Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
