Why could your secret message include only 20 of the 26 letters of the alphabet?
Did you find that it was difficult to work with only these letters?
Answers
Answer:
1. You could tell whether a given sequence was DNA or mRNA because of Uracil and Thymine base differences in both
2. Answers may vary up to you, but messages are easier to decode written in DNA
3. You are imitating RNA polymerases.
4. You are imitating RNA polymerase once again
5. The RNA strand is delivered to start the process of translation; RNA>>Protien
6. Different mutations affect different amino acid sequences because they alter the code which makes it un-easy to decode the sequence
7. Some single nucleotide mutations affect an amino acid sequence depending on what mutation it is causing. Some single nucleotide mutations do not do this because they aren't as severe and they don't cause codons to mix up.
Answer:
1
ADNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.
B It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.
2
A The cellular enzyme that carries out transcription is RNA polymerase.
B The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.
C In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.
3
A Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.
B If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.
C Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.
4
A There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.
B It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.

B. What are two reasons that this layer can contain so much water vapor? (2 points)
Answers
The two reasons that this layer ( Troposphere ) will contain much water vapor are :
AltitudeAir compressibility The layer of the atmosphere with the most water vaporThe troposphere contains so much of the water vapor present in the atmosphere due to gravity and the compressibility air. As we move higher above the earth surface, the density of the atmosphere decreases rapidly. causing the majority of water vapor to be retained at the troposphere. which is lowest part of the atmosphere closest to the earth surface.
Hence we can conclude that The two reasons that this layer ( Troposphere ) will contain much water vapor are : Altitude and Air compressibility.

An interaction that contributes to the stability of this ecosystem is: B. Species B returns compounds to the environment that may later be used by species C.
What is an ecosystem?An ecosystem simply refers to a biological community that is made up of species of living organisms (biotic factors) and the physical environment (abiotic factors) in which they exist and all interact.
Based on the schematic diagram shown in the image attached below, we can logically deduce that an interaction which contributes to the stability of this ecosystem is that Species B returns chemical compounds to the environment that may later be used by species C.

Explain why clouds are more likely to form at higher elevations. (Use the terms relative humidity and dewpoint in your answer)

Answer & Explanation:
At higher elevations, water condenses from the air and produces clouds, which often blanket lofty peaks and completely obscure them. As the clouds get saturated with moisture, rain and snow fall. The precipitation, when combined with the strong winds, results in frequent stormy weather.

Answers
Answer:
1. d.water comes "out of" or "exits" the reaction
2. a.energy goes "into" or "enters" the reaction
3. Path A
Explanation:
1) Peptide bond synthesis is dehydration reaction which means water is "dehydrated" meaning released when the reaction occurs.
2) Anytime we want to join things together we gotta use energy, these processes are anabolic reactions such as making sugars, proteins, lipids, in our cell. Since we are making protein here, we need to put energy into the reaction.
3) Path A is hydrophobic b/c they directly diffuse thru cell membrane to attach to intracellular receptor.
