Traits included physical features such as flower color. Today, these factors are called <u>alleles</u>. Mendel developed the hypothesis that some factors could be dominant, while others were <u>recessive</u>. According to his theory, a dominant factor is expressed when <u>only one factor is presen</u>t in the offspring. On the other hand, a <u>recessive</u> factor expresses its <u>phenotype</u> when <u>both factors are present</u> in the offspring. Today, the term<u> genotype </u>refers to the combination of factors possessed by an organism.

Chromosomal deletion is the loss of genetic code, caused by a segment of chromosome breaking away during DNA replication. The best answer is the third one, "when part of a chromosome breaks off and does not reattach."
The correct answer is proteins.
Proteins have four structures; (1) primary, (2) secondary, (3) tertiary, and (4) quaternary. Primary structures of proteins are formation of peptides and the peptide bonds between amino acids. Secondary structures of proteins involves the amino acid composition leading to hydrophobic interactions forming either alpha helices or beta sheets. Interactions between secondary structures of proteins will make the tertiary structure which is either soluble (globular) or insoluble (fibrous) proteins. Quaternary structures are the combination of two or more tertiary structures and these are called subunits.
Servicing the interrupt
An interrupt is the signal to the processor from the hardware which say something about the problem that needs attention. This alerts the processor to respond and command an appropriate action to the problem. This can be done by suspending activities, saving current state and executing the interrupt handler. The interruption is just temporary after finishing the problem the processor will start again the normal activities.
