Cumulative Flashcards
The healthy human body responds to foreign substances (this includes the protein coats on viruses) by producing antibodies and by rapid production of white blood cells, these are aka
leukocytes
The largest organ of your body is the _______ and is involved in ______
skin, combating pathogens
3.What is a karyotype?
a picture of ones individual chromosomes
His phrase “survival of the fittest” was incorrectly attributed to Charles Darwin. He advocated letting “nature take its course” rather than helping those less fortunate, a concept specifically repudiated by Charles Darwin. His name was
C. Lyell
The deductive method (by contrast with the inductive method)
requires the investigator to make his/her biases explicit in the form of a hypothesis
darwin’s major contribution to the field of science was in explaining one of the mechanisms by which evolution operates. this mechanism is
natural selection
the father of anthropology and originator of the 4-field approach to the study of anthropology was
F. Boaz
For a theory to be accepted the following steps must be followed first
generation of a hypothesis, testing of the hypothesis by multiple observers, failure to reject the hypothesis
the effet on your body of an error in transcription or translation may be
a non functional protein only as a result of that one cycle in which the error occurred
a nucleotide
is a complex form of a base, a sugar, and the bond between them
in the process of transcription what is happening?
mRNA is copying a message from DNA
the substitution of a different single nucleotide pair during translation may result in no change to the protein product. Why?
there are several diff codons with RNA sequences that may produce the same protein
A group of three tRNA nucleotides is called a ______ because they code for a particular ______.
codon…amino acid
immediately after DNA replication in either mitosis or meiosis, how many chromatids are there?
92
the two major purposes of meiosis are
to produce variation in offspring and to halve the diploid number of chromatids
new variation in a species is produced by
mutation
an allele is
a slightly altered form of a gene
two different alleles may code for exactly the same protein because:
of redundancy of codons for most amino acids
it would code for the same amino acid, even though because of mutations, it may have a different sequence of DNA. What is it?
an allele
chromatids are composed of
dna
three functions of mitosis
creating new cells for repair
contributing to the growth of an organism
producing new cells to replace the dead ones
where do the chromatids in the zygote’s nucleus come from?
the mother and father
a change in allele frequency over generations is
the neo-darqinian definition of evolution
if both alleles at one locus in a person have the same DNA sequence, that person is
homozygote
