Terms in this set (17)
A condition in which the blood is deficient in red blood cells, in hemoglobin, or in total volume
The pale yellow fluid portion of the whole blood that consists of water and its dissolved substances such as sugars, lipids, waste products, amino acids, hormones and vitamins
Erythrocytes (red blood cells)
Any of the hemoglobin-containing cells that carry oxygen to the tissues and are responsible for the red color vertebrate blood.
The percent of the volume of whole blood that's composed of red blood cells.
Leukocytes (White Blood Cells)
Any of the blood cells that are colorless, lack hemoglobin, and contain a nucleus.
Sickle Cell Disease
A genetic disorder caused by an uncommon form of hemoglobin. Cells are misshaped and cause a variety of symptoms including pain, blood clots and breathing problems.
Parts of the blood that helps the blood clot. They are smaller than red or white blood cells.
A triplet of nucleotide bases in transfer RNA that identifies the amino acid carried and binds to a complementary codon in messenger RNA during protein synthesis at a ribosome.
A three-nucleotide sequence of DNA or mRNA that specifies a particular amino acid or termination signal; the basic unit of the genetic code.
Messanger RNA (mRNA)
A type of RNA, synthesized from DNA, that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein.
A rare change in the DNA of a gene, ultimately creating genetic diversity.
The creation of a protein from a DNA template.
A type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis and as the genome of some viruses.
A cell organelle that functions as the site of protein synthesis in the cytoplasm; consists of ribosomal RNA and protein molecules and is formed by combining two subunits.
The synthesis of RNA on a DNA template.
Transfer RNA (tRNA)
An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and recognizing the appropriate codons in the mRNA
The synthesis of a polypeptide (protein) the genetic information encoded in an mRNA molecule. There is a change of language from nucleotides to amino acids.
