Explain why sickle cell anaemia is a form of discontinuous variation

Biology

1 answer:

Jobisdone [24]3 years ago

Answer:

Sickle Cell Anaemia can be considered a form of discontinuous variation because the variation falls within definite groups. You either have sickle cell malaria (HsHs) or you do not (HaHa). There is nothing in between and so one cannot draw a continuum (continuous scale) for Sickle cell Anaemia.

Extinction happens when there is a major climate change, then some species are unable to adapt to those changes, so they become extinct. Extinction basically occurs when species are unable to adapt quickly enough to the environment

A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut

prohojiy [21]

Answer:

D. The two students who have two fragments have one restriction site in this region.

Explanation:

The DNA samples from the cheek cells were subjected to digestion with a restriction enzyme. This enzyme is an endonuclease and cuts the DNA at a specific sequence only. This sequence is called a restriction site. If the restriction site is not present in the sample DNA, the restriction enzyme cannot cut it. The presence of one restriction site in the sample DNA would cut it into two DNA fragments.

Similarly, the presence of two restriction sites in each DNA molecule would obtain a total of three DNA fragments per DNA molecule.

Body Type: DNA code- AGTGCCTTC RNA code- ___________ Amino Acid sequence (aka protein)- ___________________ Body Type?- ________

olga2289 [7]

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.
