#38 Genetics Shorty

What is DNA? Choose all that apply.

• The molecule that carries hereditary information that codes for proteins

• It's what genes are made out of.

• It stands for Double Negation Assets

• It's a molecule that always stays in the nucleus

A subunit is what something is made from. Which one of the following is the subunit of a DNA molecule?

• phospate

• sugar

• nucleotide

• hydrogen bond

How many nitrogen bases are in all DNA?

• 2

• 4

• 6

• 8

The nitrogen bases each have long names, so they are referred to just by their first letter. Which letters represent the nitrogen bases in DNA?

• A U C G

• T A C G

• T H D Y

• D A C U

Which bases ALWAYS pair together in DNA?

• A -T and C - G

• A - G and C - T

What does protein synthesis mean?

• the process of digesting proteins

• the process of making proteins

Here is one side of a DNA strand. What are the DNA bases that match up with it in the right order?

A - A - G- A - T

• A - A - G- A - T

• T - T - C- T - A

• C - C - A - C - G

• G - G - T- G - C

How many different kinds of RNA are there?

• 2

• 3

• 4

• 5

RNA is similar to DNA but has some important differences. Choose all of the following that show the differences from DNA.

• RNA is single-stranded, but DNA is double stranded

• RNA has 5 bases but DNA has 4 bases

• RNA bases are A -U and C -G, but DNA bases are A -T and C- G

• RNA is named for its sugar called ribose, but DNA is named for its sugar, called deoxyribose

Transcription ...(choose all that apply)

• is when an mRNA strand is created to carry the DNA message out of the nucleus

• is the making of an mRNA complement (matching) sequence of bases to a sequence of DNA

• happens ONLY in the nucleus, because that's where the DNA is

• happens before translation
