Question

Not sure where I am going wrong.

Each type of pre-mRNA processing has one or more important functions. Match the function with the appropriate type of processing XAddition of 5' cap Addition of poly(A) tail RNA splicing enables movement of mRNA out of the nucleus increases mRNA stability through addition of many non-DNA-templated nucleotides facilitates binding of ribosome to beginning of mRNA involves cleavage of RNA downstream of AAUAAA consensus sequence removes non-coding regions from pre-mRNA increases mRNA stability through addition of a single modified nucleotide allows for production of more than one protein from a gene Incorrect. Whereas other statements may also be misplaced, you have specifically misplaced the statement regarding binding of the ribosome to the beginning of the mRNA. Translation begins at the 5' end of the message

Answer 1

Addition of 5' cap:

Increases mRNA stability through addition of a single modified nucleotide.

Enables movement of mRNA out of the nucleus.

Facilitates binding of ribosome to beginning of mRNA

Addition of poly (A) tail:

Increases mRNA stability through addition of many non-DNA-templated nucleotides.

Enables movement of mRNA out of the nucleus.

Involves cleavage of RNA downstream of AAUAAA consensus sequence.

RNA splicing:

Removes noncoding regions from pre-mRNA

Allows production of more than one protein from a gene
