Recombinant DNA is constructed by mixing DNA from two different sources.

The gene of interest from donor organism is NOT isolated

Recombinant DNA Technology has been widely used in IMPROVING CROP varieties.

Genetic modification is LIMITED to plants only.

Recombinant bacterial cells with human genes can be used in order to produce human proteins. One example is human insulin.

The Building blocks of nucleic acids are____.

A nucleotide of DNA may contain ______.

Which of the following Period is the earliest during which animals may have appeared?

The ______ is very unlikely because during "young" Earth time, there is still not enough oxygen on its surface and UV rays are too strong for molecular bonding occur and make life possible

A _________ is a bit likely because it is full of organic materials and when evaporated, the organic materials present in it will have a higher concentration that will lead to more favorable conditions for organic materials to combine

This is also termed as Selective breeding

_____ is a mechanism that may bring change to the gene frequency in a population because of "chance" events.

This occurs when a group or individual specie migrated from one place to another affecting the gene pool of the place that they left and the place where they arrive.

It is the process which is also known as " Survival of the Fittest.

The founder of the theory: " The principle of use and Disuse"

An English Naturalist, as we have already learned, had theorized on how species came from a common ancestor and how these species may also give birth to another species.

These are body structure from different organisms that may look somewhat similar to each other.

These are body structure that are still present in life forms but have no clear function.

These are body Structures that look the same and have the same function but different structure or features

Technological Advancement provided a new line of knowledge and evidence to prove common descent or evolution.
