Resumo de Recurso

Questão 1

Questão
Which cell does NOT have DNA in its nucleus?
Responda
  • Gamete Cells
  • Red Blood Cells
  • Muscle Cells
  • Enzymes

Questão 2

Questão
Which enzymes take part in DNA replication?
Responda
  • Lipase
  • Ligase
  • Helicase
  • DNA Primase

Questão 3

Questão
What did the first photo of DNA help scientists conclude?
Responda
  • The helix structure

Questão 4

Questão
A double helix structure means that there are objects that look like ladder-rungs.
Responda
  • True
  • False

Questão 5

Questão
[blank_start]Adenine[blank_end] is an example of a purine because it has [blank_start]two rings[blank_end], and [blank_start]cytosine[blank_end] is an example of a pyrimidine because it has [blank_start]one ring[blank_end]. This means that purines are a [blank_start]larger[blank_end] molecule and that pyrimidines are a [blank_start]smaller[blank_end] molecule.
Responda
  • Adenine
  • Guanine
  • two rings
  • one ring
  • cytosine
  • thymine
  • one ring
  • two rings
  • larger
  • smaller
  • smaller
  • larger

Questão 6

Questão
Label the enzymes required for DNA replication.
Responda
  • DNA Polymerase (Leading Strand)
  • RNA Primase
  • DNA Polymerase (Lagging Strand)
  • Primer
  • Helicase
  • Ligase

Questão 7

Questão
Which of the following are characteristics of RNA?
Responda
  • Is a longer strand than DNA
  • Is single stranded
  • Uses uracil instead of adenine
  • Contains ribose as its sugar
  • Uses RNA Ligase
  • Is a shorter strand than DNA

Questão 8

Questão
Protein Synthesis begins by copying a strand of [blank_start]DNA[blank_end] using [blank_start]RNA[blank_end] Polymerase in a process called [blank_start]transcription[blank_end]. The second step is to transport the strand of mRNA from the [blank_start]nucleus[blank_end] to the [blank_start]cytoplasm[blank_end]. After that, the tRNA connects to the mRNA with an [blank_start]amino acid[blank_end]. A cycle begins with the tRNA that eventually forms a [blank_start]polypeptide[blank_end]. In this way, protein is synthesized.
Responda
  • DNA
  • RNA
  • transcription
  • translation
  • nucleus
  • cytoplasm
  • mitochondria
  • cell wall
  • amino acid
  • protein
  • enzyme
  • polypeptide
  • amino acid chain
  • protein molecule

Questão 9

Questão
Protein Synthesis takes place in the nucleus.
Responda
  • True
  • False

Questão 10

Questão
The function of [blank_start]ligase[blank_end] is to glue together okazaki fragments.
Responda
  • ligase

Questão 11

Questão
The order of the bases determine the order of amino acids.
Responda
  • True
  • False

Questão 12

Questão
The strand of DNA that is copied is called the:
Responda
  • Leading Strand
  • Lagging Strand
  • Coding Strand
  • Start Codon

Questão 13

Questão
A gene is a section of [blank_start]DNA[blank_end] that codes for a [blank_start]polypeptide[blank_end].
Responda
  • DNA
  • polypeptide

Questão 14

Questão
Label the image with the parts used in protein synthesis.
Responda
  • DNA Strand
  • RNA Polymerase
  • Messenger RNA
  • Ribosome
  • Polypeptide

Responda
  • Transcription
  • Translation
  • Cytoplasm
  • Nucleus
  • Cell
  • Mitochondria
  • Ribosome
