Darwin's "Origin of Species" and Lamark's "Theory of Inherited Characteristics"
<span>It may be safe to say that we can rule out a concussion for this patient. The CT scan is negative for trauma to the skull, brain bleed and negative for tumors. However, there is a slight abnormality regarding the smaller size of the ventricles but otherwise unremarkable.</span>
<u>Answer</u>:
1. C. Process one describes cloning and process two describe artificial selection
Through cloning a genetically identical individual is obtained from a single individual. Through artificial selection a hybrid between two individuals with desirable traits is obtained.
2. C. Polygenic
A trait that has a continuous variation has a polygenic inheritance pattern as it is controlled by multiple genes.
3. C. The BW mice would have black and white patches
Codominant genes will produce an individual with an intermediate phenotype as both alleles are simultaneously expressed in the heterozygote.
4. D. Polygenic
Polygenic inheritance occurs when two or more genes determine a trait that has a continuous variation. Each gene has a small effect, but all together have a cumulative effect. Examples of such patterns are height, sking color, eye color, weight etc.
The answer is mRNA (messenger-RNA). In most eukaryotes, transcription occurs by firstly creating a primary
transcript. This primary transcript is
processed into a pre-mRNA that later becomes a mRNA
by removing introns. Processing of the RNA also includes
polyadenylation and 5’ capping.
