DNA Quiz Biology 30

Which cell does NOT have DNA in its nucleus?

Which enzymes take part in DNA replication?

What did the first photo of DNA help scientists conclude?

A double helix structure means that there are objects that look like ladder-rungs.

[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.

Label the enzymes required for DNA replication.

Which of the following are characteristics of RNA?

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.

Protein Synthesis takes place in the nucleus.

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

The order of the bases determine the order of amino acids.

The strand of DNA that is copied is called the:

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