DNA → RNA → Protein
This process copies genetic information from DNA into RNA, while this process uses that RNA to build a protein.
What are transcription and translation?
These cells produce keratin, while these cells produce melanin.
What are keratinocytes and melanocytes?
This is the loose, uncondensed form of DNA, while this is the condensed form of DNA.
What are chromatin and chromosomes?
This is the active form of vitamin D.
What is calcitriol?
A mutation changes the structure of a membrane protein involved in transport. This cellular function would most directly be affected.
What is membrane function/transport?
In a eukaryotic cell, transcription takes place here, while translation takes place at these structures.
What are the nucleus and ribosomes?
This process occurs when keratinocytes accumulate keratin and form protective layers.
What is keratinization?
These three-letter sequences are found on mRNA, while their complementary sequences are found on tRNA.
What are codons and anticodons?
Calcitriol increases absorption of this mineral, which is essential for maintaining normal body function.
What is calcium?
A mutation changes the structure of keratin. This important function of the skin could become weakened.
What is protection?
This molecule carries instructions from DNA to the ribosome, while this molecule carries amino acids to the ribosome.
What are mRNA and tRNA?
This superficial skin layer is avascular and primarily protective, while this deeper layer contains blood vessels, glands, and connective tissue.
What are the epidermis and dermis?
AUG serves as this during translation, while UAA serves as this.
What are the start codon and stop codon?
These proteins can act as channels or carriers to move substances, including calcium, across cell membranes.
What are membrane transport proteins?
Severe burns can cause dehydration and increase infection risk because they damage this body's protective structure.
What is the epithelial/skin barrier?
This sequence shows how genetic information can ultimately determine what a tissue does: gene → ______ → tissue → function.
What is a protein?
Epithelial cells are organized into tightly connected layers that form these structures, helping protect the body and regulate movement of substances.
What are protective barriers?
The mRNA sequence AUG–UUU–GGA–UAA produces this amino acid sequence.
What are methionine – phenylalanine – glycine?
A patient has decreased calcitriol production. This process would most directly decrease.
What is calcium absorption?
A mutation changes DNA, which changes a protein, which changes cell or tissue function. This explains why a change at the genetic level can eventually produce this.
What is a physiological change?
This pathway connects DNA to the final function of a tissue and includes transcription and translation.
What is DNA → RNA → protein → tissue → function?
This tissue is essential for homeostasis because it provides protection, regulates movement of substances, and helps maintain the body's internal environment.
What is epithelial tissue?
A change from UUU to UUG could affect this because changing a codon may change the amino acid incorporated into a protein.
What is the amino acid sequence and potentially the protein's structure or function?
Calcitriol promotes calcium absorption, while membrane transport proteins help control calcium movement at this cellular boundary; together, these processes contribute to maintaining this.
What is calcium homeostasis?
One mutation can produce large effects when it alters a protein that performs an important function; if the protein is improperly folded, this may also happen.
What is loss or alteration of protein function, potentially affecting multiple cellular and physiological processes?
