Question

Are the following statements true or false?

Determine if the following statements are true or false.

1. For a gene to control the production of a polypeptide, it must direct the linking of amino acids.

2. The type of RNA that makes a direct copy of a gene sequence is known as messenger RNA, or mRNA.

3. Typically, tRNA (transfer RNA) is much larger than mRNA.

Answer 1

2 is true, and 3 is false.

There seems to be a bit of disagreement about the first statement.  To be accurate, the gene specifies the order of the amino acids in the protein.  However, the direct linkage of the amino acids happens in the ribosome.

Answer 2

1.False

2.True

3.False

Answer 3

1 - True

2 - True

3 - False

why false

Transfer RNAs are small molecules ranging in size from 73 to 93 nucleotides in length

mRNA must have at least 100 X 3= 300 nucleotides on the basis of the triplet code.
