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.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.

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.

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.

how will you explain the importance of it in completeness of the biological organization?
The importance of biological organization is that it allows the study of natural balance between all organisms in a simple way.
The biological organization is a biological term that refers to the hierarchy of complex biological structures and systems that define life through a reductionist approach.
In this form of organization, the traditional hierarchy begins in the atom, this being the lowest level, and ends in the biosphere as a superior system.
The integrality of this organization focuses on the reciprocal relationships between each level, because the higher levels are more complex, but contain each of the organisms and parts that make up the lower levels. This type of organization must be understood as a whole.

What part of a plant cell responds to turgor pressure? *
Answer:
Cell wall. The plant cell wall accounts for the turgidity and the rigidity in plants. The cell wall protects the plant cell from bursting due to the influx of water. Rather than bursting, the cell is able to withstand the osmotic pressure exerted by the water molecules.

The comparison between the number of human genes and those of other animal species has led to many conclusions, including that _____.
Answer:
We have a lot of similar genes to those of animal kin.
Explanation:
The genes of humans and animals show more than 50% similarity and conclude the same ancestral origin.
What are genes?The gene can be described as the hereditary unit that results in the make-up of proteins for the functioning of the body.
The genes are hereditary and evolution there results in the change in the genotype and thereby phenotype with mutations.
The genes of humans and animals result in the similarity of more than m 50%. This concludes that there has been the presence of the same ancestral origin for the animal and humans.
The genetic similarity between humans and the animal species results in the conclusion of humans belong to the animal kingdom and have the same ancestral origin.
