Thymine is only present in DNA, while cytosine is only present in RNA.

DNA and RNA are both double-stranded.
.

DNA has the sugar deoxyribose, while RNA has the sugar ribose.

Question 5
A) What role does tRNA play in the translation process?(1 point)

tRNA bonds the amino acids together to then form proteins.

tRNA converts DNA into mRNA.

tRNA holds the "stop" codon to alert ribosomes to end protein production.

tRNA carries amino acids to the ribosome and helps form proteins.
