Answer:
E
Explanation:
I think bcuz arises as the result of total nondisjunction of chromosomes during mitosis or meiosi
Answer:
DNA = Genetic material of cell
RNA = Transcribed from DNA
Protein synthesis= mRNA is translated into functional protein to perform different functions
Answer:
Correct choice should be:
"SGSG"
Explanation:
The cell cycle consists of G1, S, G2 and M phase. The former three phases include the interphase and M phase is the dividing phase of cell . G1 prepares cell for DNA synthesis. S phase is the phase where DNA replication takes place. G2 phase prepares cell for cell division or M phase.
G1 phase preceeds replication or S phase and G1 phase licences DNA replication.
During other phases of cell cycle, ORC complex masks origin of replication. ORC phosphorylation takes place at S phase, which removes this omplex and unmasks origin of repication site so that replication machinery can bind to it.
DNA helicase activation: S phase
DNA helicase deposition on DNA at the replication origins: G phase (actually G1)
ORC phosphorylation: S phase
Licensing of replication origins : G phase (actually G1)
Hence correct choice should be:
SGSG
The correct choice from given option is "D", "Lactobacillus"
It seems proper to explain a bit about the types of cells here. Two type of cells are:
1) Prokaryotic: these cells have no nucleus and they are small and simple.
2) Eukaryotic: These cells have a nucleus and are large and complex as opposed to prokaryotic.
"Lactobacillus" belong to first stated category here.
Answer:
The correct answer is option B, The gametophytes grow directly from the sporophyte
Explanation:
Conifers are gymnosperm which reproduce through the exposed seeds (seeds not included in fruits) found in the cones. The trees or plant on which these conifers grow are called sporophytes. In the sporophyte, the male and female gametes fuse together to form zygote which further develops into a seed. At the right time, these seeds get dispersed into wind and they grow into new plants known as sporophytes.
