A branch of biology dealing with the ultimate physicochemical organization of living matter and especially with the molecular basis of inheritance and protein synthesis
What is molecular biology?
100
This refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations. Sometimes, individuals inherit new characteristics that give them a survival and reproductive advantage in their local environments; these characteristics tend to increase in frequency in the population, while those that are disadvantageous decrease in frequency.
What is evolution?
100
the basic physical and functional unit of heredity.
What is a gene?
100
a distinguishing quality or characteristic, typically one belonging to a person.
What is a trait?
100
the evolutionary process whereby an organism becomes better able to live in its habitat or habitats
What is adaptation?
200
a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
What is DNA?
200
1859 in his book with compelling evidence.
What year did Darwin's theory come out?
200
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
What is a molecule?
200
The passing of genetics from one generation to another.
What is heredity?
200
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
What is natural selection?
300
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes
3 kinds of proteins that all living things have in common
What is DNA replication, DNA transcription, and DNA translation
300
A protein that inhabits a gene transcription.
What is DNA?
300
a change or difference in condition, amount, or level, typically with certain limits; a different or distinct form or version of something.
What is variation?
400
the study of the chemical substances and vital processes occurring in living organisms.
What is biochemistry?
400
The female scientist screwed out of the discovery of DNA.
Who is Rosalind Franklin?
400
the haploid set of chromosomes in a gamete or microorganism, or in each cell of a multicellular organism.
What is a genome?
400
A natural process that changes RNA and DNA sequence(s).
What is a mutation?
400
Organisms produce more offspring then they need to survive, organisms have to struggle in order to survive, there is variations within species, some of those variations allow members of a species to reproduce better than others, and the organisms that survive reproduce and their offspring get their traits and the species continues to grow stronger and evolve.
How does evolution occur?
500
in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
What is mitosis?
500
copying the DNA, or a code of DNA getting erased
What are some errors in replication?
500
Scientists suggested that we started out as this organism
What is bacteria
500
Are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance.
What is a protein?
500
individuals in a population who are well-adapted to a particular set of environmental conditions have an advantage over those who are not so well adapted. The advantage comes in the form of survival and reproductive success. For example, those individuals who are better able to find and use a food resource will, on average, live longer and produce more offspring than those who are less successful at finding food. Inherited traits that increase individuals' fitness are then passed to their offspring, thus giving the offspring the same advantages.
