Answer:
Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function. Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.
Explanation:
Ginkgos have many angiosperm-like features
Explanation:
The DNA contains many regulatory sequences that are very important, even though they do not code for proteins.
For example, the expression of every gene is regulated by a region called the Promoter. The promoter sequence, located close by the coding region of the gene, usually binds the RNA polymerase (the enzyme that transcribes genes into mRNA) as well as other proteins necessary for transcription,
The promoter sequence, thus, does not itself code for proteins, but is essential for transcription and must be highly conserved so that the RNA polymerase can find it.
Answer:
The correct answer is C) It catalyzes the lengthening of telomeres, compensating for the shortening that could occur during replication without telomerase activity.
Explanation:
While replicating, the ends of the chromosomes always lose a part of the ends, therefore, the telomerase catalyzes this growing process, somehow compensating the information that will be lost.
Digestion takes place inside Iysosomes containing digestive enzymes. Hope I helped!
