If a DNA template strand had a base sequence of G-G-A-T-C-A; a) what are the codons of the mRNA produced; b) what are the antico

dons for the appropriate tRNA molecule; and c) what amino acids will be placed in the right order at the ribosome? Identifying DNA at crime scenes is a vital tool in forensics. Do you feel confident that DNA analysis is always correct? Explain your position.

Answer: a). The codons on the mRNA strand 5' C-C-U-A-G-U 3' produced are CCU and AGU.

b). The anticodons for appropriate tRNA molecules are 3'-GGA-5' and 3'-UCA-5'.

c). The amino acids that will be placed in the right order at the ribosome are Proline-Serine

DNA analysis is always correct except in cases the collected tissue samples are contaminated. DNA analysis is always correct because every individual is unique with a unique DNA code. This means that no two individuals have exactly the same DNA code, therefore there is no chance having an analyzed DNA that have the exact sequence as that of another individual.

Explanation:

a). mRNA is a type of ribonucleic acid that is used as templates for protein synthesis. It is always complementary to the parent DNA except that like other RNAs it contains Uracil base instead of Thymine. Therefore the strand is 5' C-C-U-A-G-U 3'.

b). An anticodon is a three-base sequence on the tRNA with which it base pairs with mRNA codons. In base pairing of the mRNA codon with tRNA anticodon, the first base of the mRNA codon in the 5'->3' direction pairs with the third base of the anticodon. Therefore the anticodons are 3'-GGA-5' and 3'-UCA-5'.

c). Codons are three-base sequence on an mRNA molecule that codes for amino acids. There are 64 codons, three of which codes for no known amino acid. 61 codons code for the 20 amino acids. In the genetic code, CCU codes for the amino acid proline while AGU codes for the amino acid Serine.

Answer:

A Template strand runs from 3' to 5' end. therefore, it will be:

template DNA : 3' G-G-A-T-C-A 5'

a) mRNA : 5 'C-C-U-A-G-U 3'

codons of mRNA will be : CCU and AGU

b) anticodons of mRNA will be UCA and GGA

c)AMINOACIDS will be serine and proline

Dna testing might not be accurate always, as it is likely that samples collected from crime sites will be contaminated. It is also likely that mistakes are made while sequencing the DNA sample in laboratories.

The amplitude of a wave is related to what wave characteristic?
natka813 [3]
Wavelength<span> is the distance between one point on a wave to a point on the same part of the next wave. </span>Wavelength<span> is usually measured from crest to crest or trough to trough. The crest is the highest point of the wave, and the trough is the lowest point. Amplitude is the maximum displacement of the wave.</span>

How do earth's spheres interact to cause weather/climate?
miss Akunina [59]
The atmosphere transfers heat energy and moisture across the Earth. Incoming solar radiation (insolation) is redistributed from areas in which there is a surplus of heat (the equator) to areas where there is a heat deficit (the North and South Pole). This is achieved through a series of atmospheric cells: the Hadley cell, the Ferrel cell and the Polar cell (Figure 2). These operate in a similar way to, and indeed interact with, the ocean conveyor.

For example, as the oceans at low latitudes are heated, water evaporates and is transported poleward as water vapour. This warm air eventually cools and subsides. Changes in temperature and CO2 concentrations can lead to: changes in the size of atmospheric cells (in particular, the Hadley cell is susceptible to these alterations); warming in the troposphere; and disproportionately strong warming in Arctic regions. The strong interactions between ocean and atmospheric dynamics, and the significant feedback mechanisms between them, mean that climate researchers must consider these Earth components as interlinked systems. The necessity to assess ocean-atmospheric changes at the global scale has implications for the way in which research is conducted. It is only by integrating palaeo evidence of past changes, with present day monitoring, and projected models,
