Answer:
The correct answer is A.
Explanation:
A mutagen changes the level of mutations that occur in the DNA either by affecting it physically or chemically. This helps researchers create different organisms with altered phenotypes according to what the research needs so that the genes can be investigated further under a controlled environment.
So the answer is A.
I hope this helps.
Answer:
The proteins will be transported through exocytosis; the carbon dioxide will diffuse through the membrane.
Explanation:
Diffusion is the passive transport of substances down their concentration gradient. The process moves the substances from the region of higher concentration to that of lower concentration. CO2 is a small molecule and does not have any charge. Small, uncharged molecules can diffuse through the lipid bilayer of the cell membrane. Therefore, CO2 can exit a cell by simple diffusion.
On the other hand, proteins are too large to be transported by diffusion across the cell membrane. The proteins are transported by exocytosis. During exocytosis of proteins, membrane-bound vesicles are formed inside the cell. These vesicles carry proteins in them and are called secretory vesicles. The membrane of the vesicles fuse with the cell membrane of cells and transport the proteins outside the cell.
Answer:
The Punnett square will look like this:
Rw Rw
Rw Rw
Explanation:
In order to have a white flower, both alleles must be recessive. A homozygous red flower must have two dominate alleles.
Well use (w) for white, and (R) for red.
The parent alleles are:
1 - ww
2 - RR
(see picture)
Answer:
1. Map-based genome sequencing: a; c; f; g
2. Whole-genome shotgun sequencing: b
3. Both sequencing methods: d; e
Explanation:
Map-based genome sequencing is a method that makes use of a reference genome sequence in order to determine the relative position of the DNA fragments before they are sequenced. This method is useful to determine the position of repetitive DNA fragments (for example, duplicated genes, repetitive non-coding regions, etc.) and Transposable Elements. Therefore, map-based genome sequencing is a suitable approach for large genomes (which are usually composed of repetitive sequences). On the other hand, in whole-genome shotgun sequencing, DNA sequences are obtained before the correct order of these DNA fragments is known. In this method, the genome is fragmented randomly into small DNA sequences (between 100 and 1000 base pairs), which are subsequently sequenced through the chain-termination sequencing approach (i.e., Sanger sequencing) and finally ordered by using bioinformatic tools that assemble overlapping reads.
