What is the mechanism that allows for more gene products than genes?
Group of answer choices Addition of poly A tail Signal recognition particles Alternative RNA splicing Frameshift mutations
Homework Answers
Answer-- Alternate RNA splicing
Explanation: mRNA contains introns and exons. Introns are basically junk sequence which are not get transcribed. These introns play a vital role in mRNA expression. It get spliced alternatevely to connect different exons together which produce a new combination of exons with every splicing leading to a different product in each case.

What is the function of the TATA binding protein (TBP)? Group of answer choices aids in the removal of introns from eukaryotic pre-mRNA allows prokaryotic RNA polymerase to bind to the promoter of genes allows eukaryotic RNA polymerase II to bind to the promoter of genes helps termination factors bind and terminate transcription. All of the answer options are correct.

Why would changes in the genes for transcription factors be expected to generate major phenotypic differences?...
Why would changes in the genes for transcription factors be expected to generate major phenotypic differences? They are extremely powerful genes. They can affect the expression of small numbers of other genes. Their gene products are remarkably stable. Their gene products normally denature more rapidly than other gene products. They can affect the expression of large numbers of other genes. Which enzyme, also responsible for siRNA formation, carves miRNAs from their double-stranded, fold- back RNA precursor (pre-miRNA)? Dicer ribonuclease RNA...
