Dive Biology Terms Lesson 1

molecular genetics – study of DNA structure and function on the molecular level.
marrow cavity – The hollow central cavity that extends the length of the diaphysis.
7.1.4 – Distinguish between unique or single-copy genes and highly repetitive sequences in nuclear DNA. – The 'gene coding region' (about 1.5 % of our DNA) codes for a polypeptide (around 25, 000 proteins).
Around 3% of the human genome is regulatory coding for genetic switches which control development.
The non-coding region function remains unclear but can be as much as 5-45% of the total genome.
These regions are often made of highly repetitive sequences of bases each some 5-300 bases long. These are referred to as satellite regions. These are the parts of DNA used in finger print technologies.
Species – A group of individuals that generally only interbreed with other members of the same group due to physical, behavioral, or geographical differences
annelid – A segmented worm. Annelids include earthworms, polychaetes, and leeches.
Product – a chemical substance formed as a result of a chemical reaction
photosynthesis – a way autotrophs get energy from the sun; process by which plants use the sun's energy to convert water and carbon dioxide into sugars or straches
3.3.3 Outline how DNA nucleotides are linked together by covalent bonds into a single strand. – Nucleotides a linked into a single strand via a condensation reaction
The phosphate group (attached to the 5'-C of the sugar) joins with the hydroxyl (OH) group attached to the 3'-C of the sugar
This results in a phosphodiester bond between the two nucleotides and the formation of a water molecule
Successive condensation reactions between nucleotides results in the formation of a long single strand
mitosis – A nuclear division resulting in the production of two somatic cells having the same genetic complement as the original cell.
Cell theory – "The theory that all living things are made of cells, that cells are the basic units of organisms, and that cells come only from existing cells"
Which of the following statements is TRUE about B-1 B cells and MZB cells?
abiotic factors – Nonliving components of environment.
Commensalism – A symbiotic relationship between two organisms of different species where one benefits and the other is neither harmed nor benefited
Nucleus – Structure near the center of a cell that contains the cell's DNA
Species – A unit of one or more populations of individuals that can reproduce under normal conditions, produce fertile offspring, and are reproductively isolated from other such units
important function of carbohydrates, Carbohydrates – primary fuel source of cells
Regulatory – adjective. Refers to the body's mechanisms for maintaining homeostasis.
Which оf the fоllоwing stаtements is TRUE аbout B-1 B cells аnd MZB cells?
ureters – carry urine from kidneys to urinary bladder
6 CO2 + 6 H2) –> C6H12O6 + 6O2 – carbon dioxide plus water interacts with light energy and enzymes to produce glucose and oxygen
cohesion – the attraction of molecules of the same type (ex surface tension in water)
Biennial Plants – Plants that live for two years
movement – The ability to move that all cells have, whether on a large or small scale.
