Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.
Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.
Answer:
Has the genetic disorder
Explanation:
Recessive gene are genes that are expressed phenotypically only in the homozygous condition. Homozygous is a condition where an organism contains identical alleles in homologous chromosomes. When a person is homozygous recessive for a recessive genetic disorder, then this genotype means that person has the genetic disorder since they have the identical allele.
Answer:
The thoracic cavity is "Superior" to the abdominopelvic cavity. Superior ... If an incision cuts the heart into right and left parts, a "Sagittal" plane of section was used
Explanation:
The thoracic cavity is mainly located in the chest region which also have neck and the diaphragm in it. In the thoracic cage the thoracic organs are safely placed. The thoracic cavity lies above the abdominopelvic region. The sagittal plane is the vertical plane which runs from the front to back of the body. The sagittal plane helps in splitting of two equal halves like the left and right one.
The phase contrast microscope uses out-of-phase and in-phase light rays that produce contrast areas allowing scientists to detect even a minute number of protein molecules and focus on the minute internal structures of a particle.
