Answer:
Hello! Here are the answers:
- Chromosomes are a highly condensed form of a combination of DNA and protein called chromatin. DNA strands (negatively charged) are tightly wound around these proteins called histones (positively charged) to form chromosomes.
- Mechanism genes code for for proteins that govern life processes. These genes or portions of DNA are called exons. DNA segments between these exons are called introns that strictly code for regulatory proteins and also contain genetic regulatory elements (DNA sequences that control gene expression).
- Gene expression is the process of translation of DNA sequences into proteins. The genetic code is the nucleotide sequence in the DNA itself that codes for different amino acids that combine together to form a functional protein.
Explanation:
* 2. The intronic regions are misleadingly referred to as "junk DNA" but introns code for crucial regulatory elements that control gene expression.
* 3. The genetic code determines the sequence of amino acids in various proteins.
Answer:
1) About 8.7 million.
2) They are being found everywhere.
Which of the following statements about natural selection is true? A. Natural selection favors individuals that reproduce more than others. B. Natural selection occurs in opposition to evolution. C. Natural selection can be used by farmers to generate organisms with desirable traits.
It would be A. True. I hope this helped you. Have a good afternoon
Answer:
The correct answer would be:
- mRNA sequence - UCACGGAAG,
- amino acid sequence - Ser-Arg-Lys, and
- body type - dwarf
By central dogma, we know that nucleotide sequence of deoxyribonuceic acid (DNA) form the amino acid sequence of a polypeptide chain.
Nucleotide sequence of DNA is first decoded in the form of nucleotide sequence of mRNA (messenger ribonucleic acid) under the process of transcription. The sequence of RNA is complementary to the nucleotide sequence of template strand of DNA. In addition, uracil is present in RNA in place of thymine.
tRNA (transfer RNA) then deciphers the codon sequence of mRNA into amino acid sequence of polypeptide sequence by the process of translation.
Now, given DNA sequence is AGTGCCTTC.
so, the mRNA sequence would be UCACGGAAG.
Codon sequence is UCA CGG AAG.
So, the amino acid sequence would be Ser-Arg-Lys.
Hence, the trait of showman performer would be dwarfism.
Codon sequence chart is attached for reference.
