what are the metric prefixes? What are their values?
giga (1 billion), mega (1 million), kilo (1 thousand), hector(100), deka (10), deci (1/10) centi (1/100), milli micro (1/1million) pico (1/1billion)
How is a chromosomal mutation different from point mutation?
chromosomal mutations are mutations that involve changes in one or a few nucleotides known as point mutations because they occur at a single point in the DNA sequence.
How is cancer related to the cell cycle?
A cancer cell will divide uncontrollably due to the mutation of the DNA that produces a cell cycle controlling protein.
what is an adaptation?
The ability of living organisms to adjust themselves to their surroundings.
what are the different levels of organization in ecology?
organism, population, community, ecosystem, biome, and biosphere.
translate AGCCATTGCA into RNA
UCGGUAACGU
if we want to give a bacteria cell new genes, what four techniques can we do to try and encourage transformation.
1) Competent cell preparation, 2) transformation of cells, 3) cell recovery, and 4) cell plating.
what does metastasize mean?
the development of secondary malignant growths at a distance from a primary site of cancer.
Do individuals evolve?
Individual organisms don't evolve.
what is bio diversity?
the variety of all living things and their interactions.
what are three differences between DNA and RNA?
1. DNA is a double helix and RNA is a single stranded DNA.
2. DNA has Thymine and RNA has uracil.
3.RNA has the sugar ribose while DNA has the sugar deoxyribose.
How are florescent proteins useful to cell biologists?
they can serve as probes of environments within living cells.
what are 3 ways meiosis is different from mitosis?
meiosis: Maintenance of chromosome number (diploid)
Takes place in somatic cells/growth
No crossing over/no variations
mitosis:
Reduction/halving of chromosomes (haploid)
Occurs in reproductive cells/gonads/produces gametes
Crossing over takes place/variation occurs
why is Charles Darwin famous?
Charles Darwin is primarily known as the architect of the theory of evolution by natural selection
Define carrying capacity?
A species' average population size in a particular habitat
put the following things from biggest to smallest:
length of DNA, cell, chromosome.
Cell<chromosome<length of DNA
what information does a karyotype tell us?
helps identify chromosome abnormalities as the cause of malformation or disease
what's the difference between co dominant and incomplete dominant traits?
In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
Do all living things leave fossil evidence behind?
No, not all living things leave fossil evidence behind because the fossilization process is destructive and rare
what is one difference between primary and secondary succession?
The primary succession occurs following an opening of a pristine habitat. The secondary succession is a response to a disturbance
how many hydrogen bonds does Cytocine and Guanine have? adenine and thymine?
Guanine and cytosine have 3 hydrogen bonds and adenine and thymine have 2 hydrogen bonds.
what are homologous chromosomes?
Having inherited the same versions (alleles) of a genomic marker from each biological parent
what are vestigial structures?
features of an organism that are considered to have lost much or all of their original function through evolution.
