The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.
<h3>What are restriction enzymes?</h3>
They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.
The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

This statement is true.
In the case of autosomal dominant disease, the person is either homozygous (which is very rare) or heterozygous. On the molecular level, either the mutation produced a new deleterious protein for the organism, or the mutation affected an existing protein in the physiological state and that a 50% activity is not enough to compensate for the needs. of the body.
In case of autosomal recessive disease, the sick person is always homozygous. If the two loci each have a different mutant allele, it is called a "composite heterozygote". People with autosomal recessive inheritance disorder have "mandatory heterozygote" parents.
The answer is d. <span>animals with transmissible diseases separated from healthy animals.

Answer:
There are many things that can be read from ripple marks in sedimentary rocks. To start, a geologist looks at: the types (sizes, composition, shapes) of grains in the rock, the height of the “waves”, the distance between peaks (highs) and troughs (lows), whether the rock seems to be lying in its original position, and the internal shapes of the ripples (by looking at the edges of broken pieces). They also seek to determine the age of the rock and information about other rocks lying below and above the specific rock.
