Resumo de Recurso

Questão 1

Questão
What is a gene?
Responda
  • A "recipe" for how to make a protein.
  • A sequence of DNA nucleotides that provide a chemical message for printing a protein.
  • Denim pants

Questão 2

Questão
What is a locus?
Responda
  • A "fixed address" on a chromosome
  • A cicada
  • A "street map" for where certain genes are on the chromosomes

Questão 3

Questão
What is an allele?
Responda
  • A group of genes that determine a trait
  • One of different versions of a gene
  • Variations of a protein recipe

Questão 4

Questão
Blood Type A alleles
Responda
  • A101
  • C3PO
  • A201

Questão 5

Questão
Blood Type B allele
Responda
  • Type B only has one allele
  • B101
  • All about that bass

Questão 6

Questão
Blood Type O allele
Responda
  • O01
  • O02
  • O03

Questão 7

Questão
Why are the "O" allele blood-type proteins non-functional?
Responda
  • Because they are the wrong sequence of amino acids.
  • A nucleoide has been deleted from the 258th position on the gene.
  • Every amino acid after the deletion is wrong!

Questão 8

Questão
Varied alleles lead to....
Responda
  • Varied proteins
  • The same proteins
  • Both functional and non-functional proteins

Questão 9

Questão
What is a phenotype?
Responda
  • A record player
  • An inherited physical characteristic
  • What you look like, based on your genes

Questão 10

Questão
One-gene phenotypes are
Responda
  • The physical characteristics resulting from an allele at a single locus
  • For example, what color socks you buy
  • For example, blood type

Questão 11

Questão
Poly-genic phenotypes are...
Responda
  • Alleles at two or more loci
  • Produce proteins that interact to produce a physical trait
  • For example, skin color, hair color, and eye color

Questão 12

Questão
We inherit
Responda
  • 1 set of chromosomes
  • 2 sets of chromosomes
  • 3 sets of chromosomes

Questão 13

Questão
What is a recessive allele?
Responda
  • An allele that is only expressed when there are no dominant alleles around.
  • An allele that is always expressed
