3.mRNA

4.recombination

5.DNA and RNA are both made up of nucleotides. RNA is comprised of adenine, uracil, guanine, and cytosine. DNA is made up of adenine, thymine, guanine, and cytosine. DNA is a double-stranded chain of nucleotides comprised of base pairs that form a double helix. RNA is often a single-stranded chain of nucleotides.

6.The central dogma states that DNA contains the genetic code needed to make proteins—a process known as gene expression. Transcription and translation are the two steps involved in gene expression. In transcription, the DNA code is turned into RNA. In translation, the RNA sequence provides instructions to the cellular machinery to manufacture polypeptides, which become proteins.

7.Replication is the duplication of DNA, and it is important because, in cell division, each daughter cell must contain an exact copy of the original cell's DNA, since DNA contains the instructions required to make all of the cell's tissues. Recombination is the natural process for genetic sequences in a chromosome or between chromosomes to exchange genetic information. Recombination is important in nature because it produces genetic variations that may be preserved because of natural selection. Recombination also can be used in the laboratory to combine the genetic code of two different organisms.

Would vision and audition be considered "higher senses” in non-human animals? Why or why not?
Dimas [21]

Answer:

Not necessarily

Explanation:

There are animals in which vision and audition are more specialized than in humans, while in other species this relation fails. For example, in predatory birds, the vision clarity surpassing human eyesight, since this sense is required for effective prey capture. Conversely, in the European mole (<em>Talpa europaea</em>), which is a mammal that lives mostly underground, the vision is seriously short-sighted. These are clear examples that "the function makes the organ", ie., phenotypic features such as vision and audition are selected in the course of evolution depending on the fitness that they confer to the species in particular environmental conditions.

Which class of enzymes catalyzes reactions involving the formation of double bonds?
vodka [1.7K]

Lyases

Lyases are class of enzymes that catalyzes reactions involving the formation of double bonds.

Lyases are class of enzymes that catalyzes the joining of C-C ( carbon to carbon), C-O (carbon to oxygen), and C-N (carbon to nitrogen) bonds by hydrolysis or oxidation. These bonds are usually held by the process of elimination which leads to the formation of new double bonds or cyclical molecules. Examples of lyases include; aldolase and adenylate cyclase.

Proliferation of lymphocytes occurs immediately after __________.
melamori03 [73]
<span>Proliferation of lymphocytes occurs immediately after activation, as well as the encounter of antigen. First, these antigen are bound, after which activation begins. Activation immediately leads to proliferation, as well as differentiation. Proliferation is an increase in the number of something, in this case, in the number of lymphocytes, or white blood cells. </span>
