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 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.
