The statement that is true is active transport moves against the concentration gradient.

<h3>WHAT IS ACTIVE TRANSPORT</h3>

Active transport is one of the two types of cellular transport that involves the movement of molecules against a concentration gradient.

This moves that movement occurs from a region of lower concentration to a region of higher concentration. Since movement is against a concentration gradient, it involves input of energy (ATP).

Therefore, the statement that is true is active transport moves against the concentration gradient.

What are cells that produce new cartilage matrix called?.
Nastasia [14]

Answer:

The stem cells differentiate into chondroblasts. 3. These chondroblasts, located at the periphery of the old cartilage, begin to produce and secrete new cartilage matrix. As a result, they push apart and become chondrocytes, each occupying its own lacuna.

When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference
REY [17]

Answer:

The best answer to the question: What is the most likely explanation for this observation, would be, B: RNA processing removes the different segments from the mRNA molecules of each person prior to translation.

Explanation:

In order for cells to work, they depend on one of the four major macromolecules; proteins. These proteins are the messengers that carry out genetic commands from the DNA and they will ensure that all processes, including transcription and translation of new proteins, are carried out correctly. In order to produce proteins, the first step is for the DNA to be transcribed into mRNA, a nucleic acid that carries out the information on the DNA for protein generation. Once transcription stops, mRNA undergoes a series of clipping and reorganizing steps that will ensure that when it is decoded for protein formation, the process will be successful. These control steps are all part of the RNA processing mechanism that enures mRNA will successfully be translated into working proteins.

The reason why from genes of different people, a very similiar protein chain may result, is also explained from the fact that codons (a grouping of three nucleotides present in mRNA), when read by ribosomes, and coupled by tRNA, can pair these codons with similar amino acids. Thus, one codon, or similar codons, may code for a singular amino acid. However, mechanisms in the cells prevent these kinds of anomalies, by repairing the mRNA sequence before it is translated into protein.
