in the presence of a regulatory protein the lac operon is _____.
Answer:
The correct answer is : B. not transcribed
Explanation:
The regulatory protein of the lac operon is a repressor. A operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway. The genes of an operon are sequentially ordered after the promoter.

Which is the BEST statement about joint flexibility? A. It is constant for any joint type. B. It is constant within a family. C. It is consistent between an individual's joints. D. It varies from joint to joint. Please select the best answer from the choices provided. A B C D.
Which is the BEST statement about joint flexibility?
Answer : D
Explanation : It varies from joint to joint.
Hope this helps you!
The amount of flexibility can vary greatly from joint to joint and is affected by various factors such as joint structure, muscle strength and elasticity, age, and physical activity level. Hence option D is correct.
What is joint flexibility?Joint flexibility refers to the range of motion (ROM) of a joint or a group of joints. It is the ability of a joint to move through its full range of motion without causing any pain or discomfort.
Joint flexibility is an important aspect of physical fitness and is essential for performing daily activities and participating in sports and exercise.
Joint flexibility is determined by several factors, including the anatomy of the joint, the length and elasticity of the muscles surrounding the joint, and the presence of any injuries or medical conditions affecting the joint.
Some joints, such as the shoulder joint, are naturally more flexible than others, like the knee joint.
Flexibility can vary between individuals and between different joints in the same individual. For example, someone may have very flexible hip joints but limited flexibility in their shoulder joints.
Similarly, an individual's joint flexibility can also be influenced by age, gender, and activity level.
Hence option D, It varies from joint to joint. is correct.

The top strand of the DNA molecule was used as a template to transcribe the mRNA
Agree
Disagree
Why
Answer:
The upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA. The -35 region (TTGACA) and -10 region (TATATT) of the promoter sequence and the transcriptional start site (the A) is indicated on the coding strand.The primary electron acceptor in photosystem II is __________. Group of answer choices P700 P700 P680 P680
Answer:
680
Explanation:
When the P680 special pair of photosystem II absorbs energy, it enters an excited (high-energy) state. Excited P680 is a good electron donor and can transfer its excited electron to the primary electron acceptor, pheophytin.

what gives animal cells their shape and structure?
Answer: Animal cell's shape and structure are determined by the cytoskeleton.
What is the cytoskeleton?
The cytoskeleton is present in all animal cells, prokaryotic (bacterial) cells contain a very rudimentary version of it, while plant cells do not have one at all. It consists of several types of large molecules that provide physical support to the cell as well as internal transport along its length for organelles like endoplasmic reticulum (ER), mitochondria, vacuoles, etc. The three main components are microtubules, intermediate filaments and microfilaments which give rise to different structures within the cell. Microtubules are long cylindrical tubes made up of two protein subunits (alpha and beta tubulin) that form a hollow tube. These are the main components of the cytoskeleton, they provide support to the cell while also having transport capacity for organelles like endoplasmic reticulum (ER), mitochondria, vacuoles, etc. Microtubules are dynamic structures which means their state is constantly changing i.e., growing, shrinking or moving around depending on requirements of the cell.
In creating recombinant DNA, some restriction enzymes produce ______ ends in both the source DNA and plasmid DNA, and these ends can stick to each other by ______.
Answer: Single-stranded; complementary base pairing
Explanation:
Restriction enzymes are essential components of recombinant DNA technology because they can be extracted from bacterial cells and utilized in the lab to modify DNA fragments, including those that contain genes (genetic engineering).
What recombinant DNA produce by restriction enzymes?An isolated bacterial protein called a restriction enzyme breaks DNA at specific sequence-specific locations to produce DNA fragments with a known sequence at each end.
For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.
Therefore, In creating recombinant DNA, some restriction enzymes produce Single-stranded ends in both the source DNA and plasmid DNA, and these ends can stick to each other by complementary base pairing.
