The gene pool of the population will remain relatively constant.
Answer:
D. 4E-BP1 binding to elF4E prevents loading of the mRNA onto the ribosome.
Explanation
In eukaryotic organisms, the eIF4E translation initiation factor functions by directing the ribosomes to the 5'-terminal cap structure of the messenger RNA (mRNA) in order to start the translation. Moreover, phosphorylation is a posttranslational modification of specific amino acids on proteins that play diverse cellular functions by altering protein stability, location, and/or enzymatic activity. It has been shown that elF4E phosphorylation is increased in response to cellular stimuli that induce translation in the ribosomes (e.g., growth factors, hormones, etc). The eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) is a repressor of mRNA translation which is phosphorylated and inactivated by growth factors and hormones, thereby inhibiting 4E-BP1 binding to elF4E and consequently activating translation.
Answer:
64.
Explanation:
It is 64 because there are 20 amino acids with four bases ( A,T,C and G).
and genetic code can be read in triplets and also the four bases can occupy the positions. Eachh amino acid can be coded by the triplet codons. A triplet codon shows three nucleotides of the mRNA template that can code for amino acid
Therefore the number of codons is 4×4×4= 64.
Answer:
it may be:
C and D and B the longer the empty space the longer the sound well go
Answer:
1. Roots: anchor the plant in soil and absorb water and minerals
2: Stem: Holds the plant upright and bear leaves, branches and fruits.
3. Leaves: Carry out photosynthesis to make food for other plant parts.
4. Flower: serves as organ of reproduction to maintain the continuity of the species.
Explanation:
1. Roots: The cells of roots are specialized to penetrate the soil deep to anchor the plant and absorb water and minerals for nutrition of plants.
2: Stem: The cells of stem impart mechanical strength to keep the plant upright and bear leaves, branches and fruits.
3. Leaves: Cells of leaves have chlorophyll pigment to carry out photosynthesis to make food for other plant parts.
4. Flower: Some of the cells of flowers produce male and female gametes that fuse leading to seed formation. Seed germination maintains the continuity of the species.
