nucleus function correct answers Stores hereditary material and coordinates the cells activities (growth, intermediary metabolism, protein synthesis, and reproduction) Endoplasmic Reticulum (ER) function correct answers folding and transport of proteins in vesicles to Golgi apparatus. Ribosome...

Describe the function of the following cellular structures: - Nucleus - ER - Ribosomes - Peroxisomes - Lysosomes - Mitochondria - Golgi Apparatus - Plasma Membrane correct answers Nucleus: Contains DNA that codes for proteins Rough ER: Has ribosomes, site of protein synthesis, transports ...

Where does translation always start? correct answers cytoplasm Do proteins destined for the nucleus (eg TF) also get translated in the cytoplasm? correct answers Yes, they must exit the nucleus to get translated and then get transported back into the nucleus What strategies do you think the ce...

Why is it important that proteins get targeted to the right cellular location? (11) correct answers Each protein has a specific function at its intended destination in the cell and failing to complete that task can result in the cell not functioning properly. Ex. in cystic fibrosis the CFTR protein ...

What are the three main components of the cytoskeleton and what are their main functions? correct answers Microtubules, microfilaments and intermediate filaments that help form the cytoskeleton to create stability, structure, and allow movement What are the main similarities and differences betwe...

Describe endocrine, paracrine, and autocrine signaling. correct answers Endocrine: An endocrine cell releases a hormone into the blood stream to target a receptor on the target cell. Paracrine: A signaling cell releases a local mediator to target cells (neighboring cells). Autocrine: A cell re...

Cytoskeleton: A) 3 main components B) main functions correct answers A) actin filaments, microtubules, and intermediate filaments B) actin - sense the environment and direct movement microtubules - for transport intermediate - help keep the cell shape, to anchor organelles What are th...

What are the main organs affected by cystic fibrosis? correct answers Lungs, any organ that has epithelial cells, mucus, and secretory system which requires regulation of that mucus Describe the main function of the CFTR protein and how it is regulated. correct answers responsible for regulating ...

What are the three main components of the cytoskeleton and what are their main functions? correct answers Microfilaments: movement microtubules: transport of cellular materials intermediate: support What are the main similarities and differences between the three components of the cytoskeleton?...

Gene correct answers The sequence of genomic DNA that codes for a functional product and all necessary elements to properly regulate its expression What is the most likely type of biochemical change in a protein that results in a recessive and dominant mutation correct answers recessive: Changes ...

describe the signals and mechanisms required for import into the peroxisome correct answers peroxisomal matrix proteins have targeting sequences which are recognized by Pex5 receptor and brought to peroxisomal matrix what is a peroxisome? correct answers organelles that carries out redox reaction...

what is the central dogma or molecular genetics? correct answers every cell has the same genomic DNA -> transciption (DNA-mRNA) -> translation (RNA-proteins) -> offspring List exceptions to central dogma correct answers 1. RNA/retroviruses 2. noncoding DNA 3. Prions (proteins that cha...
