Answer:
The correct answer is - Methionine, serine, histidine, aspartate, glycine
Explanation:
The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.
New DNA strand: 3'-TACAGGGTGCTACCCACT-5'
mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'
The translation of this mRNA would be on the basis of chart
AUG - Methionine (start codon)
UCC - serine
CAC - histidine
GAU - aspartate
GGG - glycine
UGA - stop codon
The peptide chain would be - Methionine, serine, histidine, aspartate, glycine
Answer:
polar bears begin to eat goose
Explanation:
A) Taiga
This is shown by the cold winters and the animal life in the example.
Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
