Biology

Answer:

The correct answer is: a. A single mRNA can be translated simultaneously by several ribosomes.

Explanation:

Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.

To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a <u>polysome </u>and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.

Can someone please help me with 1 evolution question ?
geniusboy [140]
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

A population of cheetahs has a birth rate of 5 and a death rate of 15. Immigration is 2, and emigration is 4. What is its popula
kirill115 [55]
Since the death rate is higher than the birth rate we can assume that it will be negative. 5-15 is -10 for their life. immigration is also lower than the emigration. 2-4 is -2. adding -2 and -10 will give us -12, hope this helps.

A dna replication bubble forms at a specific sequence of bases called the ___________. see section 15.3 (page 321) .
julsineya [31]

The answer is the origin of replication. This is where the replication bubble is formed. Two opposite replication forks (Y-shaped regions) of DNA are formed when the double helix is unzipped by DNA helicases. Transcription factors, polymerase III and primer then bind to the region to begin transcription.

Fluid shift from vascular to interstitial can cause the water in blood is decreased, causing the other component level in blood seems to be increased(hemoconcentration).
In this case, hematocrit is one of the marker in laboratory that can be used for assessing hemoconcentration.
