Answer:
One amino acid
Explanation:
This question is describing the occurrence of the process of mutation, which is the alteration in the genetic sequence of a gene. In this question, a DNA sequence was given as follows: TAC-ATC-CAT-CAG-TTA-CGC. However, a SUBSTITUTION MUTATION took place in such a way that the thymine base was replaced by a guanine base to have mutated sequence: GAC-ATC-CAT-CAG-TTA-CGC.
Since the mutation is a kind of substitution mutation, only the codon affected by that mutation will change. This DNA sequence will be transcribed into a mRNA sequence. The mRNA will be read codon by codon (a group of hree nucleotides) to produce amino acid. Since one codon will be involved, one amino acid will be affected.
Answer:
Hemophilia
Explanation:
This is a disorder in which a blood coagulation factor is missing from the blood, so if the person with the disorder gets even a small injury, he'll bleed a lot due to absence of proper blood coagulation.
It's more common in males than females because females have two X chromosomes. If they have one recessive allelle on one X chromosome, while the other has the dominant allele, they're going to be asyptomatic carriers of the recessive allele.
However, since males have only one X chromosome, having the recessive allele means that they'll suffer from hemophilia. There's no chance of them being just carriers unlike the females.
A baby animal knows what to do after birth just from natural instinct. Human babies do not get taught how to breath or cry, they know to do so because they would die otherwise.
Answer:
RNA
Explanation:
Transcription is the first process of protein synthesis and it involves copying the information encoded in the genetic material (DNA) to a RNA molecule. It involves making a complementary strand of mRNA from a DNA template.
The process of transcription commences when an enzyme called RNA polymerase binds to the promoter region of a gene on the DNA, signalling the unwinding of its double-stranded structure. The RNA polymerase then adds nucleotides to the growing RNA molecule, complementary to the ones it reads on the DNA. The RNA synthesized during transcription is called messenger RNA (mRNA).
The mRNA is then used as a template for amino acids synthesis during translation.

What are the techniques of cutting flowers?
Custom-cutting the flower stem in open air and immediately placing it in the vase of water is usually fine. Cut all flowers and foliage about one inch from the bottom of a main stem. Make the slice at an angle of about 45 degrees. Cutting at an angle provides a larger exposed area for the uptake of water
