Exam 3: Cell Structure and Genetic Control

One possible reason that the proteome is so much larger than the genome is that mRNAs can be spliced in alternative ways thereby increasing the number of products produced from a particular gene.

The spooling of DNA around histones creates particles called

How are the phospholipids arranged to form the plasma membrane?

The organelle involved in the production of energy is the

The division of the cytoplasm in mitosis is called

Receptor-mediated endocytosis would allow cells to selectively remove molecules from the extracellular fluid.

The process of gene expression occurs as

How many genes does it appear that humans have?

Regulatory proteins are degraded outside of lysosomes by binding to ___ and then broken down by the proteasome.

The folded inner membrane of a mitochondrion is called

RNA strands such as siRNA and miRNA can prevent gene expression in mRNA.

In the nucleus of a diploid cell,the amount of cytosine would equal the amount of

The process of cell death in which cell membranes remain intact but become bubbled and the nuclei condense is known as

Proteins that will be secreted by the cell are made on the granular endoplasmic reticulum.

Cyclins are a group of proteins which promote different phases of the cell cycle.

The organelle that acts as enzymes for protein synthesis is the

Membrane enclosed organelles containing oxidative enzymes that form hydrogen peroxide are

Pseudopods can be used for both amoeboid movement and phagocytosis.

DNA replication is

Folds of the plasma membrane that increase surface area are called
