Compare and contrast p-dependent and p-independent termination of transcription in prokaryotes.

iVinArrow [24]

Compare and contrast two mechanisms for transcriptional termination in bacteria.

(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid

(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination

The graphs below show the changes in crab color at one beach.

vazorg [7]

Answer:

C. Both light tan and dark tan body color provided an advantage to the crabs on this beach, but not necessarily in other crab habitats.

Explanation:

The changes in the number of light tan and dark tan body color of crabs that occured can be described as a diversifying or disruptive selection.

This disruptive selection occurs when individuals with extreme traits on both ends of the spectrum become selected against individuals of ntermediate or medium traits.

In the case of the crab, their environment favors the selection of both extreme values as against those intermediate individuals, as both light tan and dark tan body color of the crabs gives them advantage over others in this particular environment. This may only be obtainable in this environment or similar beach environment with the same settings and conditions.

Few ways animals use air

GrogVix [38]

Answer:

they use to live

Explanation:

As they breath out carbon dioxide the plants take in the carbon dioxide and make air with it. Animals also use air to do their day to day things like eat.

What is the purpose of RNA

valina [46]

RNA, in one form or another, touches nearly everything in a cell. RNA carries out a broad range of functions, from translating genetic information into the molecular machines and structures of the cell to regulating the activity of genes during development, cellular differentiation, and changing environments.

Can you identify the class of organic molecule to which these molecular structures and examples belong? Part A Sort these items

sattari [20]

There are four classes of organic molecules that are essential to all living organisms.

1. Carbohydrates:

Components: monosaccharides. Functions: energy for cell, raw material, energy storage, and plant cell support Ex: glucose, starch, glycogen, cellulose

2. Lipids (dont form polymers): Components: glycerol, fatty acid, components of a fat molecule Functions: energy storage, cell membrane components, and hormones Ex: fats, phospholipids, and steroids

3. Proteins:

Components: amino group, carboxil group, R group, and amino acid Function: enzyme, structural protein, movement, transport, communication, defense, storage, receive signals Ex: lactose, hair, tendons, muscles, hemoglobin, signal proteins, antibodies, egg albumin, receptor protein

4. Nucleic acids:

Components: phosphate group, nitrogeneous base, ribose or deoxyribose, nucleotide Functions: heredity, DNA

Ex: code for proteins, DNA and RNA
