Answer 8

generation of a hypothesis, testing of the hypothesis by multiple observers, failure to reject the hypothesis

Question 9

the effet on your body of an error in transcription or translation may be

Answer 9

a non functional protein only as a result of that one cycle in which the error occurred

Question 10

a nucleotide

Answer 10

is a complex form of a base, a sugar, and the bond between them

Question 11

in the process of transcription what is happening?

Answer 11

mRNA is copying a message from DNA

Question 12

the substitution of a different single nucleotide pair during translation may result in no change to the protein product. Why?

Answer 12

there are several diff codons with RNA sequences that may produce the same protein

Question 13

A group of three tRNA nucleotides is called a ______ because they code for a particular ______.

Answer 13

codon…amino acid

new variation in a species is produced by

Answer 16

mutation

Question 17

an allele is

Answer 17

a slightly altered form of a gene

Question 18

two different alleles may code for exactly the same protein because:

Answer 18

of redundancy of codons for most amino acids

Question 19

it would code for the same amino acid, even though because of mutations, it may have a different sequence of DNA. What is it?

Answer 19

an allele

Question 20

chromatids are composed of

Answer 20

dna

Question 21

three functions of mitosis

Answer 21

creating new cells for repair
contributing to the growth of an organism
producing new cells to replace the dead ones

a change in allele frequency over generations is

Answer 23

the neo-darqinian definition of evolution

Question 24

if both alleles at one locus in a person have the same DNA sequence, that person is

Answer 24

homozygote

Question 25

one of the ways in which new alleles enter a population is when those carrying them join and mate with the “host” population that didnt have those alleles.

Answer 25

gene migration/flow

Question 26

Native americans had never experience smallpox, measles, or influenza until these diseases were introduced into the Americas by infected eurpoeans. and estimated precontact north american population of approximately 12-15 million was subsequently reduced to less that two million.

Answer 26

genetic drift/population bottleneck
