Answer:

Lower gravitational force due to lower mass.

Explanation:

Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.

aleksklad [387]

Full Question (figure attached):

Nucleic acid segments and ar

DNA and RNA are nucleic acids that can store biological information based on the sequence of their nucleotide monomers. Figure 1 shows a short segment of each of the two types of nucleic acids. Which of the following best describes a structural difference between DNA and RNA?

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups

Answer:

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.

Explanation:

A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases - this is false. Both contain four types of nitrogenous bases. DNA contains cytosine, guanine, adenosine and thymine, whereas RNA contains cytosine, guanine, adenine, and uracil.

B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose. - this is true, each nucleotide in DNA contains a deoxyribose sugar, whereas each nucleotide in RNA contains a ribose sugar

C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand - this is false. DNA is composed of 2 strands, and RNA is composed of one, but the DNA strands run in an anti-parallel configuration (one runs 5'-3', the other runs 3'-5')

D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups - this is false, both DNA and RNA nucleotides contain phosphate groups

A part of an mRNA has the sequence CCG. Which change to this sequence
Flauer [41]

Answer:

A single nucleotide changes in CCG which will result in missense mutation can be many possibilities.

Explanation:

Missense mutations  

CCG codes for Proline amino acid

• Mutation in first nucleotide codes for  

 UCG specifically encodes Serine

 ACG specifically encodes Threonine  

 GCG specifically encodes Alanine                              

                                                                                      Missense mutation  

• Mutation in second nucleotide specify for coding

 CUG specifically encodes Leucine

 CAG specifically encodes Glutamine  

 CGG specifically encodes Arginine

• Mutation in Third Nucleotide will not result in missense mutation because any point mutation in third nucleotide of codon will encode same amino acid i.e Proline.
