Answer:
Energy drives the cycling of matter within and between systems. Energy drives the cycling of matter within and between systems in aerobic and anaerobic conditions. Photosynthesis and cellular respiration (including anaerobic processes) provide most of the energy for life processes.
Bacterial cells don’t have nucleus so they are prokaryotic. Eukaryotic cells have a nucleus.
Heritability describes a proportion of difference among people that is attributed to genetics.
Heritability is the static used in breeding and genetic works and generally, it is the ratio of variation due to the differences between genotypes to the total phenotypic variation for a character in a population
Answer:
If an mRNA strand is 6399 nucleotides long, it will code for 2132 amino acids, as the last triplet is the terminating codon.
Explanation:
Codons are found in the RNA chain and are made up of nucleotides trios, whose specific sequence determines the genetic code.
There are 4 nitrogenous bases in RNA - Adenine, Guanine, Cytosine and Uracil - which when combined in trios give rise to 64 possible codon combinations that code for 20 amino acids, so an amino acid can be formed by more than one codon.
Determining how many amino acids are encoded according to the amount of nucleotides in the mRNA would be as easy as <u>dividing the number of nucleotids in the chain by 3</u>, but considering that the last codon is not taken into account, since it is the termination codon.
- Amino acids = (amount of nitrogenous bases in mRNA / 3) - 1
- Amino acids = (6399 / 3) - 1
- Amino acids = 2133 - 1 = 2132
