Question
DNA is a double helix made of two [blank_start]anti[blank_end]parallel strands of [blank_start]nucloe[blank_end]tides linked by [blank_start]hydrogen[blank_end]-bonding between [blank_start]comple[blank_end]mentary [blank_start]base[blank_end] pair.
Answer

  • nucleo
  • hydrogen
  • comple
  • base

Question 4

Question

Answer
  • 46

Question 5

Question

Answer
  • 5
  • 8
  • 13
  • 24

Question 6

Question
Only a purine will fit with a pyrimidine between the sugar-phosphate backbones, when base pairing occurs.
Answer
  • True
  • False

Question 7

Question
The lagging strand goes in a 3 prime to 5 prime direction.
Answer
  • True
  • False

Question 8

Question
The decoding of mRNA into a protein is called [blank_start]translation[blank_end].
Answer
  • translation
  • transcription
  • initiation
  • elongation
  • termination

Question 9

Question
[blank_start]DNA[blank_end] is too large to leave the nucleus, but [blank_start]RNA[blank_end] can. Therefore [blank_start]DNA temporarily unzips[blank_end] and is used as a template to assemble [blank_start]complementary[blank_end] nucleotides into [blank_start]mRNA[blank_end].
Answer
  • DNA
  • RNA
  • mRNA
  • tRNA
  • DNA temporarily unzips
  • RNA temporarily unzips
  • complementary

Question 10

Question
Which of the following unzips DNA?
Answer
  • RNA polymerase
  • DNA polymerase
  • RNA primer
  • DNA primer

Question 11

Question
Who was responsible for creating the endosymbiotic theory?
Answer
  • Pasteur
  • Rosalin Franklin
  • Watson and Crick
  • Miller and Urey

Question 12

Question
In eukaryotic chromosomes, replication can be initiated at several different points whilst in prokaryotes the entire genome is replicated at once.
Answer
  • True
  • False

Question 13

Question
At the leading strand, DNA [blank_start]helicase[blank_end] splits the [blank_start]DNA[blank_end] into its two anti-[blank_start]parallel[blank_end] strands, creating a replication [blank_start]fork[blank_end].
Answer
  • helicase
  • DNA
  • parallel
  • fork

Question 14

Question
Genetic information is copied from [blank_start]DNA to RNA[blank_end] because [blank_start]DNA[blank_end] is too large to leave the nucleus, but [blank_start]RNA[blank_end] can. Therefore [blank_start]a part of the DNA[blank_end] is temporarily unzipped by [blank_start]RNA polymerase[blank_end] and is used as a [blank_start]template[blank_end] to assemble complementary nucleotides into [blank_start]mRNA[blank_end]. The [blank_start]messenger RNA[blank_end] then goes through the pores of the [blank_start]nucleus[blank_end] into the cytoplasm to attach to a [blank_start]ribosome[blank_end]. This process is called transcription.
Answer
  • DNA to RNA
  • RNA to DNA
  • DNA
  • RNA
  • a part of the DNA
  • a part of the RNA
  • RNA polymerase
  • RNA primase
  • DNA polymerase III
  • DNA polymerase I
  • ligase
  • template
  • mRNA
  • tRNA
  • messenger RNA
  • transfer RNA
  • nucleus
  • ribosome

Question 15

Question
A codon is a series of [blank_start]3[blank_end] adjacent bases in a [blank_start]mR[blank_end]NA molecule that codes for a specific [blank_start]amino[blank_end] [blank_start]acid[blank_end].
Answer
  • 3
  • mR
  • amino
  • acid

Question 16

Question
Label the following diagram of translation
Answer
  • anticodon
  • tRNA amino acid
  • mRNA
  • tRNA

Question 17

Question
The mRNA that is released at the end of transcription is called pre-[blank_start]mRNA[blank_end]. [blank_start]pre-mRNA[blank_end] needs to undergo changes before it is [blank_start]exported out of[blank_end] the [blank_start]nucleus[blank_end] to protect it from the cytoplasmic environment.
Answer
  • exported out of
  • imported into
  • nucleus
  • cytoplasm
  • membrane
  • mRNA
  • tRNA
  • pre-mRNA
  • pre-tRNA

Question 18

Question
The anticodon goes in a [blank_start]3[blank_end]' -> [blank_start]5[blank_end]' direction.
Answer
  • 3
  • 5

Question 19

Question
Ribosomes are the site of which of the following processes?
Answer
  • protein synthesis
  • meiosis
  • mitosis

Question 20

Question
A ribosome alone cannot synthesize a polypeptide chain.
Answer
  • True
  • False

Question 21

Question
The intitial pre-MRNA contains [blank_start]intr[blank_end]ons that are removed from the pre-mRNA by [blank_start]spliceo[blank_end]somes, while the [blank_start]ex[blank_end]ons are spliced together.
Answer
  • spliceo
  • intr
  • ex

Question 22

Question

Helicase - [blank_start]Unwinds DNA double helix strands[blank_end] DNA Polymerase III - [blank_start]produces complementary strands[blank_end] Ligase - [blank_start]connects the Okazaki fragments[blank_end] DNA Polymerase - [blank_start]replaces RNA primers with DNA[blank_end]
