Answer:
In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy .
In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid). For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).
Explanation:
All living things are made up of cells. All non-living things are not.
A dill pickle is technically "living" since it was once growing as a plant. Therefore, the dill pickle has cells.
However, the rest of the items do not, as they are non-living things.
Answer:
#19 = The cell is an animal cell because it's missing the organelles required in plant cells(chloroplast, vacuoles, and the cell wall)
#20 = The mitochondria would be most likely to be affected because it's the powerhouse of the cell, provides energy, and imports proteins. I hope this helps.
Explanation:
Answer: You can add neutral solutions with a pH of 7, like water. Water will dissolve the alkaline/acidic pH to near 7 and 8, which are safe to drink.
Hope this helps you!
Answer:
b. mRNA from DNA
Explanation:
Transcription is the process of synthesis of RNA using a DNA template strand. The process of transcription occurs inside the nucleus in eukaryotes as their DNA is present in the nucleus.
The process includes unwinding of DNA double helix to expose the DNA template strand. The enzyme RNA polymerase binds to the specific start sites on the DNA template strand and starts making its RNA copy.
The newly formed RNA undergoes modification in eukaryotes before serving as a template for protein synthesis. However, in prokaryotes, the process of transcription and translation can occur simultaneously.
