Answer:
The correct answer is D sister chromatids;centromere
Explanation:
After DNA replication during s phase or synthesis phase of interphase of the cell cycle,each chromosome has a copy and the cell that is newly formed is now 4n.
We cal these identical pairs sister chromatids and they are held together by a centromere
Answer:
articulates with the temporal bone to form the temporomandibular joint
Explanation:
The mandible is the lower bone of the lower jaw of the human face which consists of the ramus and the front bones and teeth.
The mandible contains an articular structure for articulation called "condyle" which help in the formation of temporomandibular joints.
The temporomandibular joint is the joint formed between the lower jaw or mandible and the temporal bone of the skull. This allows the free movement of the lower jaw.
Thus, the selected option is the correct answer.
Answer: Precipitation I believe
Answer:
<em>The evidence that suggests RNA appeared before DNA is the fact that RNA can act as an enzyme to self-edit their own genetic code. </em>Moreover, it has the ability to store genetic information, while transfer and ribosomal RNA have the ability to translate genetic information into proteins.
Explanation:
RNA has a great capability as a genetic molecule, it once had to carry on hereditary process on its own. It is absolutely sure that RNA was the first molecule of heredity. However, a single stranded RNA is rather unstable and easily damaged by enzymes. By essentially multiplying the existing RNA molecule, and using deoxyribose sugar instead of ribose.
<em>The DNA evolved as a much more stable form to pass genetic information with accuracy. It shows a biological evolutionary purpose .</em>
