The answer is A. Fertilizer
The other answer choices don't make sense Herbicide is a poison that kills plants, Pesticide is an insect killer, while a Growth Hormone is designed to help the plant grow not to put nutrients into the soil.
Answer:
There are many points at which eukaryotic gene expression can be controlled, through pretranscriptional control, transcriptional control, and posttranscriptional control
Explanation:
The pretranscriptional control determines the accessibility of chromatin to the transcription machinery. It is affected by supercoiling and methylation. It is also known as epigenetic regulation, and it does not depend on the sequence but on the conformation of the DNA.
While transcriptional control determines the frequency and / or speed of transcription initiation through the accessibility of the start sites, the availability of transcription factors and the effectiveness of promoters.
The post-transcriptional control is the one that is exercised once the transcript has finished synthesizing. It can be of several types:
• Maturation control: As the RNA adjustment can be made.
• Transport control: Most RNA has to go out to the cytoplasm to perform its function. For this they have to cross the pores of the nuclear membrane, where you can select the RNAs that will be transported and those that will not.
• Stability control: The half-life of RNA can be regulated by the expression of RNAs or mRNA stabilizing proteins in the cytoplasm.
• Translational control: It is exercised on the frequency with which the mRNAs begin to be translated. It can also affect the frequency with which proteins mature and the availability of enzymatic effectors.
Answer: this is because with triplet sequences, diversities would be generated and the possibility of overlapping is minimal
Explanation:
Answer:
(D) Z
Explanation:
Cellular respiration is a catabolic process by which cells produce energy by oxidising respiratory substrates such as glucose. It is a multistage process occurs in cytoplasm and in mitochondria of a cell. The first stage of cellular respiration is called glycolysis or EMP (Embden, Meyerhof and Parnas) pathway. This stage occurs in the cytoplasm of a cell which is labeled by Z in the given image.
