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.

Why are marriages between blood relatives prohibited in the united states and other countries?
HACTEHA [7]
Marriages or any form of sexual relations between blood relatives is incest and is completely prohibited in the United States and most other countries of the world.

There are two reasons for this:

1. Religious: Most major world religions prohibit marriages between blood relatives. In countries where church and other religious institutions had a strong following, incest remains a crime.

2. Biological: Medical Science has proven that off-springs of close relatives e.g. brother-sister, first cousins and even second cousins have a high chance of genetic mutation which can lead to various health issues. This is the main reason why modern societies prohibit incest

Can someone please explain the difference between DNA and RNA and mRNA, worth 1️⃣5️⃣ points
Blababa [14]
Temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled

I just need a bit of help answering this one. (:

If we take the wolf as a species, then we can easily find its place and evolutionary path through this cladogram of chordates. The wolf is a vertebrate, so we start from vertebrae. It is an animal that has jaws and paired appendages. Continuing further up the cladogram we reach the development of lungs, and the wolfs have lungs for breathing. Then we come to the development of four limbs, and the wolfs have four limbs. Next comes the endothermy, meaning that the animal is able to regulate its own body temperature, thus it is warmblooded, and the wolfs are warmblooded animals. As last we come to the mammals, and the wolfs are part of the mammals, so we can classify them in that branch of the chordate cladogram.
