Which letter in the picture below depicts the lagging strand in DNA replication?

Letter B since it is copied from 3' to 5

Letter A since it is copied from 5' to 3'

Letter A since it is copied from 3' to 5'

Letter B since it is copied from 5' to 3'

Where does mRNA transcription occur?

In the nucleus where the DNA is

What are the 4 RNA nitrogen bases?

adenine, uracil, cytosine, and guanine

adenine, thymine, cytoplasm, and guanine

adenine, thymine cytosine, and guanine

adenine, uracil, cytoplasm, and guanine

provides information from DNA to ribosomes

transfers amino acids to the ribosomes

Which phrase best describes translation?

converts mRNA into a polypeptide

catalyzes bonds between amino acids

produces RNA from DNA molecules

recycles tRNA molecules for reuse

Which statement is true about RNA?

RNA is usually single stranded and contains the base uracil

RNA is usually double stranded and contains the base thymine

RNA is made in the nucleus and stays there to carry out its function

Which of the following correctly describes transcription

MRNA is made from a DNA template

proteins are made from amino acids

What best explains the interaction between tRNA and mRNA during translation?

anticodons on the tRNA line up with complementary codons on the mRNA

anticodons on the mRNA line up with complementary codons on the tRNA

tRNA attach amino acids to the complementary mRNA sequence

mRNA attach amino acids to the complementary tRNA sequence

A mutation is defined as:

A change in the cell's structure

Anything that changes in an embryo

Any change in the physical features of a human

Why are insertion and deletion (frameshift) mutations so harmful?

They change all of the codons from the mutation on down the line, which changes the amino acid sequence

They insert things that an organism doesn't need.

They often delete things that organisms need.

Insertion and deletions are not any more harmful than substitution mutations.
