How many amino acids could be specified if codons consisted of two nucleotides instead of three? What problem would this present for an organism making proteins using all 20 amino acids? I need help with the last part i dont undertsand

Answers

Answer 1

Answer:

This could result in a mutation.

Explanation:

A change in the DNA can affect the work of cells because it can cause a mutation; it can be a good mutation or bad. The three main mutations that occur are Insertion, Deletion and Substitution. Insertion is when DNA base(s) are added in, Deletion is when DNA base(s) are removed. Lastly, Substitution is when DNA base(s) are switched on. All of these mutations can have effects. These effects are Silent effect, Missence, and Nonsense. Silent effect is a mutation that does not change the sequence of amino acids in a protein. Missence is a mutation that causes the sequence of amino acids to change. This can cause incorrect protein folding and protein malfunction. Nonsense is a mutation that causes an early stop codon. This effect leads to a protein that is too small. Also a Frameshift can occur. Framshift is when the reading of a frameshift is moved over by one or more bases such that every subsequent amino acid changes. An example of a frameshift is THE CAT ATE THE RAT. If you insert an A at the Beginning this happens ATH ECA TAT ETH ERA T. IN Conclusion there are two Mutations that also play a role in this Point Mutation and Chromosomal Mutaion. Point Mutation is when a single DNA base is either substituted, inserted or deleted from the sequence. Chromocomal Mutation is when large pieces of a chromosome or an entire chromosome is either substituted, inserted or deleted.

Answer 2

16 amino acids could be specified if codons consisted of two nucleotides instead of three.

What do you mean by Codons?

Codons may be defined as an arrangement of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid.

A mutation may be responsible for such problems that would present for an organism making proteins using all 20 amino acids.

A synonymous mutation means that one base within the codon gets substituted for another. Even though the same amino acid is still produced.  

It changes the sequences of nucleotide bases within the codon, but ultimately the coded amino acids remain the same.

Therefore, it is well described above.

How can students in the photograph use the net to sample the invertebrates in the river.

Answers

Answer and Explanation:

Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.

There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.

Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.

Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.

Based on that appraisal and other representations by lending personnel, the Cassies elected to refinance their home with a $495,000 adjustable rate mortgage. Lending personnel told them their home would appreciate and they would be able to sell or refinance the home at a later date before having to make higher monthly loan payments.

The Cassies stopped making payments on the mortgage, which had a balance due of $625,000. Soon after, the fair market value of the house was $200,000.
