How many nucleotides are in 12 mRNA codons?<br><br> 12<br> 24<br> 36<br> 48
Mrrafil [7]

The correct answer is C. 36

Explanation:

In genetics, a nucleotide refers to the basic units that form genetical material. On the other hand, a codon refers to a sequence of three nucleotides in the mRNA or messenger RNA which are a set of molecules that take genetical information from ADN to the ribosome of the cell. This implies in the case of a 12 mRNA codons there are 36 nucleotides as each of the codons contains three nucleotides which means by multiplying the number of codons by three (number of nucleotides) it is possible to know the total number of nucleotides in an RNA sequence or in this case 12 (codons) x 3 (nucleotides) = 36 nucleotides.

Both cerebrum and cerebellum have gray matter in their surface cortex and deeper nuclei. True or False
worty [1.4K]

The cerebrum and the cerebellum are parts of brain:  

Cerebellum: lies under the cerebrum. Its purpose is to coordinate movements of the muscles, to maintain posture and balance.

Answer:

The correct answer is - aerial view of the fault line of San Andreas which represents a transform or strike-slip type of boundary.

Explanation:

The picture is given in the question is an aerial view of the fault line of San Andreas.

A fault is a planar break or intermittence in a volume of rock across due to rock-mass movement that leads to significant relocation or displacement. In San Andreas, the faultline represents the transform or strike-slip type of boundary.

Observation:

  1. A complex zone of crushed and broken rock
  1. Many smaller faults branch

Bezzdna [24]
It is d. If it was adaptation, the organism would have stayed in order to adapt. The species moved in order to not go extinct. It can not be speciation, because a new species was not made. It is stimulus. It experienced too much heat, so it left.
