Your Name (Optional)

Q1 Beginner 1 pts

According to the video, what are the three parts that make up both DNA and RNA nucleotides? Video Reference:
"The nucleotides of both RNA and DNA have three parts: a phosphate, sugar, and a base..."

A phosphate, sugar, and a base A protein, sugar, and a base A phosphate, protein, and a base A sugar, base, and amino acid

Q2 Intermediate 2 pts

What specific difference in bases exists between DNA and RNA? Video Reference:
"The bases in DNA are adenine, thymine, guanine, and cytosine... The bases in RNA are adenine, uracil..."

RNA has uracil instead of thymine RNA has thymine instead of uracil RNA has adenine instead of guanine RNA has cytosine instead of adenine

Q3 Intermediate 2 pts

The video mentions three specific types of RNA. What does mRNA stand for and what is its role? Video Reference:
"mRNA, which stands for messenger RNA. mRNA's job is to carry a message based off of the DNA..."

Messenger RNA - carries a message based off of DNA Modified RNA - modifies DNA structure Multiple RNA - creates multiple DNA copies Micro RNA - controls small DNA segments

Q4 Advanced 3 pts

According to the video, if you have 8 DNA nucleotides, how many base pairs would you have? Video Reference:
"So 8 DNA nucleotides would have 8 bases. DNA bases pair like this- and that's 4 DNA base pairs..."

4 base pairs 8 base pairs 16 base pairs 2 base pairs

Q5 Beginner 1 pts

In eukaryotic cells, where is DNA typically located compared to RNA? Video Reference:
"In eukaryotic cells, DNA tends to be found in the nucleus while you can find RNA both in and out of ..."

DNA in nucleus, RNA both in and out of nucleus Both only in nucleus Both only outside nucleus DNA outside nucleus, RNA in nucleus

Q6 Beginner 1 pts

The video states that DNA is generally double-stranded while RNA is generally single-stranded. Video Reference:
"DNA is generally double stranded, and if focusing on these two strands of nucleotides here, you can ..."

True

False

Q7 Intermediate 2 pts

Which structural feature allows DNA to store more genetic information than RNA? Video Reference:
"DNA structure and information storage capacity..."

Select all correct answers

DNA's double helix structure DNA's deoxyribose sugar DNA's thymine base DNA's phosphate backbone

Q8 Intermediate 2 pts

According to the video, what is the specific sugar found in RNA? Video Reference:
"The sugar in DNA is deoxyribose and the sugar in RNA is ribose..."

Ribose Deoxyribose Glucose Fructose
