This is the force of attraction between an object and the earth due to gravity.
weeeeeb [17]

Answer:

Gravitational force

Explanation:

Gravitational force is the force that attracts an object down to the earth. It’s also the reason why we don’t float on this planet. This force is also why anything that isn’t thrown up must come down.

In space and other planets with little or no gravitational force ,organisms float over there which makes its inhabitation by organisms very difficult.

Why is RNA polymerase a good name for the enzyme that carries out transcription
KATRIN_1 [288]

Answer:

RNA Polymerase plays an important role in the process called transcription which result in the in the synthesis of RNA from DNA molecule.

Explanation:

RNA polymerase helps in the addition of ribonucleotides in the growing RNA strans that is synthesized from template DNA .

      one ribonucleotide is joined to the adjacent ribonucleotide by the formation of phosphodiester bond.

      RNA polymerase is named so because this enzyme helps in the polymerization of ribonucleotides leading to the formation of a Primary RNA transcript.

Several organisms have a homologous protein (inherited from a common ancestor) that is highly similar at the amino acid level. Y
8_murik_8 [283]

Answer:

The correct answer is: C. third nucleotide position.

Explanation:

  • Genes located on the chromosomes encodes for proteins.
  • A Gene is made up of a  Deoxyribonucleotide (DNA) sequence which is transcribed into the messenger Ribonucleotide (mRNA) sequence by the help of RNA polymerase.
  • This mRNA sequence is further translated into the amino acid sequence, that folds to form the functional protein, by the help of the Ribosome.
  • The Ribosome reads the mRNA sequence in the form of triplets (three nucleotide together) and each such triplet nucleotide codes for an amino acid.
  • Each such triplet nucleotide is known as a Codon.
  • The Genetic Code is a table which represents the  amino acid encoded by each codon.
  • However, the Genetic Code is degenerate in nature. This means that one amino acid can be coded by more than one codon.
  • This is because, among the the three nucleotide positions in a codon only the first two determine the specificity of the amino acid while the third nucleotide, also called the wobble nucleotide, is not specific. Presence of any nucleotide in the third position of the codon will not alter the amino acid encoded by the codon.
  • In the given question, organisms producing homologous protein have similar amino acid sequence but they vary in the corresponding nucleotide sequence of the gene which codes for the homologous protein.
  • This is because at the nucleotide level the variation lies in the wobble nucleotide position that occupies the third position in the codon.

Which assisted reproductive technology involves the maturation and fertilization of the egg within laboratory glassware, followe
son4ous [18]
It is in vitro fertilization (IVF).
IVF is a type of assisted reproductive technology used for infertility treatment. It includes the steps like removing an ovum from the woman's ovaries, fertilisation (sperm cell from is injected using a microscopic needle, directly into each harvested ovum from the woman) outside the body, embryo transfer to the same or another woman's uterus after a few days.
